ICs for Audio Common Use AN7164 30 W BTL audio power amplifier s Overview The AN7164 is an integrated circuit designed for 30 W (VCC = 21 V, 8 ) output power amplifier. High power output (BTL 30 W), low distortion and low noise are realized. High reliability is obtained due to various kinds of protectors built in. Furthermore, on-off of output is possible from standby terminal. 7.70.3 Unit : mm 12 (10.0) 3.6 29.750.30 28.00.3 20.00.3 (1.27) (1.3) R1.8 * High power output * Low distortion, Low noise * Low shock noise when power supply is turned-on, off * Built-in standby function * Built-in protection circuits (Temperature, Overcurrent, Load short circuit, Output GND short circuit) 0.6 s Features +0.10 0.25 -0.05 2.54 1 0.6 -0.05 (1.27) (10.0) +0.15 (12.5) 1.450.15 1.20.1 (1.2) 19.10.3 21.90.3 HSIP012-P-0000A s Applications * Stereo, Karaoke, TV s Block Diagram 11 12 2 VCC 6 Input circuit Driver circuit SEPP output circuit 10 1 Ripple filter Protection circuits for Temp.

To avoid this, it is necessary to forcibly flow a current of 1 mA into pin 1 at standby-on. s Technical Information * PD Ta curves of HSIP012-P-0000A PD T a 65 62.5 60 55 50 Infinite heat sink Rth (j-c) = 2C/W Rth (j-a) = 42C/W Power dissipation PD (W) 45 41.7 40 35 31.3 30 25 20 17.9 15 10.4 10 5 3.0 0 0 1C/W heat sink 2C/W heat sink 3C/W heat sink 5C/W heat sink 10C/W heat sink Without heat sink 25 50 75 100 125 150 Ambient temperature Ta (C) s Application Circuit Example 2 k 100 F VCC = 21 V 1 000 F 2 0.047 F 220 100 F 4 1 F VIN 12 1 11 10 100 F 2.2 5 0.1 F 7 8 100 F 2.2 0.1 F 8 3 6 0V 5V 9 3 |
