30 W BTL audio power amplifier

The AN7164 is an integrated circuit designed for 30 W (V CC = 21 V, 8 W ) output power amplifier. High power output (BTL 30 W), low distortion and low noise are re- alized. High reliability is obtained due to various kinds of protectors built in. Furthermore, on-off of output is possible from standby terminal. n Features

• 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) n Applications
• Stereo, Karaoke, TV n Block Diagram HSIP012-P-0000A Unit : mm 7.7±0.3 (12.5) 19.1±0.3 21.9±0.3 (1.2) (10.0)(10.0) 29.6±0.3 20.0±0.3 0.6 28.0±0.3 29.75±0.30 f3.6 R1.8 121 +0.15 –0.052.540.25 1.45±0.151.80±0.15 1.2±0.1 3.5±0.3 +0.10 –0.05 3GND 9GND 4 2 Input circuit Ripple filter Input circuit Driver circuit Protection circuits for Temp.

ICs for Audio Common Use AN7164 n Usage Notes Standby-on (i.e. an application of 5 V to pin 6) under a high temperature may cause no-output due to the malfunction of rapid discharging circuit of the ripple filter. To avoid this, it is necessary to forcibly flow a current of 1 mA into pin 1 at standby-on. n Technical Information
