| POWER&RF Low profile audio power amplifier IC IC TK17119F DESCRIPTION The TK17119F is an audio power amplifier IC capable of low voltage operation. The coupling capacitors to the speaker are not required, because of BTL (Bridged Tied Load) configuration. Its very small SON3024-8 package is useful for space mounting space. Built-in stand-by function can reduce supply current at stand-by mode. Therefore, it is suitable for any battery-powered portable equipment. TK17119F BTL SON30248 FEATURES Low Operating Voltage Range: VOP=2.0 to 16V Low Supply Current: ICC=2.7mA Standby Function: ICCS<1A Maximum Output Power: PO.MAX=400mW(typ.) @VCC=6.0V, RL=32 Low Total Harmonic Distortion: THD=0.5%@VCC=6.0V, RL=32 : VOP=2.0 to 16V : ICC=2.7mA : ICCS<1A : POMAX=400mW (typ.) @VCC=6.0V, RL=32 : THD=0.5%@VCC=6.0V, RL=32 APPLICATIONS Speaker drive DC motor drive(forward, reverse) Other general use DC PACKAGE OUTLINE Part name Package Marking Pin configuration See Next Page ORDERING INFORMATION Ordering information TK17119FTL TK17119F SON3024-8 AAA Package code F: SON Storage direction TL: Left type ABSOLUTE MAXIMUM RATINGS Parameter Operating Voltage Range Operating Temperature Range Power Dissipation Operating Frequency Range Symbol VOP TOP PD fOP Rating 2.0 to 16.0 -40 to +85 600 20 to 200 Unit Remarks V C mW kHz 9-4 2005 WINTER POWER&RF ELECTRICAL CHARCTERISTICS Parameter Supply Current Stand-by Supply Current Amp1 Voltage GainAmp1 1 Amp2 Voltage GainAmp2 2 Output Power 2 2 Total Harmonic Distortion 2 2 Power Supply Rejection Ratio 1 1 Output Voltage 2 2 Output Offset Voltage Output Voltage High Level Output Voltage Low Level Input Bias Current VST Input Voltage High LevelVST H VST Input Voltage Low LevelVST L Symbol ICC ICCS AV1 AV2 PO2 THD2 PSRR1 VO2 VO VOH VOL IIB VSTH VSTL 50 -30 2.55 0 4.9 0.2 30 30 MIN Value TYP 3.4 0.1 90 0 MAX 5.0 1.0 0.35 1.0 VCC=6.0V, VST=6.0V, RL=32, TA=25C Units Conditions mA RL= A VST=0V dB Amp-A dB Amp-B mW VCC=6V, RL=32, THD<10% VCC=6V, RL=32, % PO=125mW, Gv=34dB dB C1=, C2=0.01F, DC V VCC=6V mV RFB=75k, RL=32 V ISO=75mA V ISI=75mA nA 4pin at operating mode V at stand-by mode V 77 -0.35 250 0.5 2.0 0 16 0.8 BLOCK DIAGRAM VST Standby on C1 5F C2 1F VIN CIN RIN 1F 3k 620 RFB 75k Vo2 1 VREF GND 8 7 +VIN VCC Vcc 2 3 Vcc Vo1 RL 32 6 5 -VIN 10F 4 2005 WINTER 9-5 |
