la4815m notes on using the ic 1. voltage gain settings (pins 1 and 8) the voltage gain of the power amplifier is fixed by the internal resistors. ? pins 1 and 8 be left open : approximately 26db ? pins 1 and 8 connected to gnd : approximately 39.5db note that the voltage gain can be changed using two resistors. (see fig. 1) ? voltage gain setting : according to the resistor connected between pin 8 and pin 2 (gnd1) * voltage gain = 20log (20 (625 + rvg1)/(125 + rvg1)) ? output dc voltage setting : according to the resistor connected between pin 1 and pin 2 (gnd1) * rvg1 = rvg2 must be satisfied. in addition, the voltage gain can also be lowered to appr o ximately 20db (when using 5v or 6v power supply) by an application such as shown in fig. 2 below. ? voltage gain setting : according to the resistor connected between pin 8 and pin 5 (out) * voltage gain = 20log (20 (125 + rvg3)/(10,125 + rvg3)) ? output dc voltage setting : according to the resistor connected between pin 1 and pin 6 (v cc ) * set the resistor values so that the pin 5 (out) dc voltage is approximately half the supply voltage. example : when rvg3 = 10k , rvg4 = 22k (when v cc = 6v) however, note that using this method to greatly lower the voltage gain deteriorates the characteristics, so the voltage gai n should be lowered only to approximately 20db. in addition, when using a high supply voltage (7v or more), the clipped waveform may invert, so this voltage gain reduction method must not be used in these cases. la4815m rvg1 rvg2 gain2 gain1 gnd1 v cc out la4815m rvg3 rvg4 gain2 gain1 gnd1 v cc out 1 2 3 4 8 7 6 5 1 2 3 4 8 7 6 5 fi gure 1 figure 2 2. signal source impedance : rg the signal source impedance value rg affects the ripple rejecti o n ratio together with input coupling capacitor cin, so rg should be as small as possible. therefore, when attenuating the signal at the cin front end as shown in fig. 4, the constants should be set in consideration of these characteris tics. using the smallest resistor rg1 value possible is recommended. in addition, when setting the signal level, the voltage gain sh ould be set on the la4815m side and the input front-end should be configured using only the input coupling capacitor, cin, as shown in fig. 5 in order to maximize the ripple rejection ratio. vbias 100k + - pre-amp rg2 cin rg1 rg out other ic ro la4815m in cin other ic ro la4815m cin in 3 3 out in 3 figure 4 fi gure 3 figure 5 no.a1373-6/14
la4815m 3. mute control pin (pin 7) the internal power amplifier circuit can be disabled and audio mute is turned on by controlling the voltage applied to pi n 7. control can be performed directly using the cpu output port, but digital noise from the cpu may worsen the la4815m noise floor. therefore, inserting a series resistor, rm1 (1 to 2.2k ) as shown in fig. 6, is recommended. ? mute on : low ? mute off : high or open in addition, the pin 7 dc voltage is dependent on the su pply voltage, so a reverse current flows to the cpu power su pply line when the pin 7 voltage is higher than the cpu su pply voltage. in these cases, connect a resistor, rm2 (see fig. 7) between pin 7 and gnd to lower the pin 7 dc voltage as shown in fig. 6. note that when not using the mute function, pin 7 must be left open. rm1 * for reverse current prevention 1k rm2 v dd v ss cpu i/o port la4815m gnd v cc 30k 30k 40k 10k 7 figure 6 reverse current prevention resistor value : rm2 (reference value) when v7 is set to approximately 2.5v rm2 ? v cc 10 100 7 5 3 2 7 5 3 2 1000 71 1 1 3 91 supply voltage, v cc ?v impedance, rm2 ? k 5 figure 7 4. mute control timing when performing mute control, exercise control at the timing shown in fig. 8. during power-on : twu = 0 to 50ms * pins 6 and 7 can also rise simultaneously. during power-off : twd = 100 to 200ms pin 6 (v cc ) pin 7 (mute) twd twu figure 8 no.a1373-7/14
la4815m 5. popping noise reduction during power-off the power supply line can be directly controlled on and off without using the mute function. however, when using a hi gh supply voltage, the shock noise and aftersound during power-off tends to worsen. one method of coping with this is to connect a capacitor between pin 6 (v cc ) and pin 7 (mute) as shown in fig. 9 so that the auto mute function operates during power-off. recommended value = 1 f + + cmt 1f cv cc la4815m v cc mute 6 7 figure 9 6. input coupling capacitor (cin) cin is an input coupling capacitor, and is used for dc cutting. however, this capacitor is also used to improve the ripple rejection ratio, which changes according to the capacitance value (recommended value = 1 f). in addition, this capacitor also affects the transient respon se characteristics during power-on and wh en mute is canceled, so the constant should be set in considerati on of these characteristics. design reference value = approximately 0.33 to 3.3 f ? ripple rejection ratio : increasing the capacitance value in creases t he rate, and reducing the value reduces the rate. ? rise response speed : increasing the capacitance valu e reduces the speed, and reducing the value increases the speed. ? popping noise : increasing the capac i tance value reduces the noise, and reduc ing the value increases the noise. 7. output coupling capacitor (cout) cout is an output coupling capacitor used for dc cutting. however, this capacitor, cout, in combination with load im pedance r l forms a high-pass filter and attenuates the low frequ ency signal. take into account the cutoff frequency when determining the capacitance value. in addition, norma lly a chemical capacitor is used for this capacitor, but the capacitance value of chemical capacitors d ecreases at low temperatures, so the va lue should be set in accordance with this characteristic. the cutoff frequency is expressed by the following formula. fc = 1/(2 r l co ut) 8. output phase compen sation capacitor (cosc) the cosc capacitor is used to prevent output oscillation. use a ceramic capacitor (recommended value = 0.1 f) with good high frequency char acteristics, and locate this capacitor as close to the ic as possible. 9. power supply capacitor (cv cc ) the cv cc capacitor is used t o suppress the ri pple component of the power supply line. normally a chemical capacitor (recommended value = 10 f) is used for this capacitor. however, ch emical capacitors have poor high frequency characteristics, so when using a cpu, ds p or other ic that generates digital noise in the set, it is recommended that a power supply bypass capacitor (ceramic cap acitor, recommended value = approximately 0.1 f) be added to reject high-frequency components. locate this bypass capacitor as close to the ic as possible. no.a1373-8/14
la4815m 10. signal mixing methods the following methods can be used to mix a beep, key tone or other signal into the audio signal. note that when input to pin 8 is sele cted, amplification of signals input from pin 3 changes according to impedance z8 connected to pin 8. 10-1. mixing method using resistors in the pin 3 input front end vbias 100k + - pre-amp rg2 rg1 signal-2 signal-1 other ic ro rg3 vout2 vout1 ro la4815m cin vin pin 3 input impedance : zin = 100k in out1 out2 3 figure 10 10-2. method using input to pin 8 ? first signal system (signal-1) voltage gain : vg1 vg1 = 20log (vout/vin1) = 20log (4 (125 + z8) (500 + (125 z8/(125 + z8)))/(25 z8)) * z8 = r1 + ro ? seco nd signal system (signal-2) voltage gain : vg2 vg2 = 20log (vout/vin2) = 20log (10000/(125 + r1)) * fc2 = 1/(2 cin 2 (r1 + 125)) vbias 100k + - + - pre-amp rg2 rg1 signal-2 signal-1 other ic ro r1 vin2 ro la4815m cin cin2 vin1 + 125 10k pwr - amp 500 out1 out2 in gain2 3 8 5 vout out figure 11 11. short-circuit between pins turning on the power supply with some pins short-circuited may cause deterioration or breakdown. therefore, when m ounting the ic on a board, check to make sure that no short-circuit is formed between pins by solder or other foreign substances before turning on the power supply. 12. load short circuit leaving the ic for a long time in the condition with a lo ad short circuit may cause deterioration or breakdown. therefore, never short-circuit the load. 13. maximum ratings when used under conditions near the maximum ratings, even a slight fluctuation in the conditions may cause the maxi mum ratings to be exceeded, possibly resulting in a br eakdown or other accidents. therefore, always provide enough margin for fluctuations in the supply voltage and other conditions, an d use within a range not exceeding the maximum ratings. no.a1373-9/14
