HA13158A Datasheet | Hitachi Semiconductor

Description The HA13158A is four-channel BTL amplifier IC designed for car audio, featuring high output and low distortion, and applicable to digital audio equipment. It provides 34 W output per channel, with a 13.7 V power supply and at Max distortion. Functions - 4 ch BTL power amplifiers - Built-in standby circuit - Built-in muting circuit - Built-in protection circuit (surge, T.S.D and ASO) Features - Low power dissipation - Soft thermal limiter - Requires few external parts (C:3, R:1) - Popping noise minimized - Low output noise - Built-in high reliability protection circuit - Pin to pin with HA13153A/HA13154A/HA13155/HA13157/HA13158 Block Diagram C2 0.1 µ/16 V C1 4400 µ/16 V 14 2 1 STBY IN-1 Buffer & Mute-1 Amp-1 VCC 13.2 V 18 PVCC2 6 PVCC1 3 4 5 IN VCC 7 IN-2 11 Buffer & Mute-2 Amp-2 8 9 15 IN-3 13 Buffer & Mute-3 Amp-3 16 17 19 IN-4 23 MUTE 10 R1 7.5 k Buffer & Mute-4 Protector (ASO, Surge, TSD) 12 C3 10 µ/10 V 22 TAB Unit R: Ω C: F Amp-4 20 21 Notes: 1. Standby Power is turned on when a signal of 3.5 V or 0.05 m A is impressed at pin 2. When pin 2 is open or connected to GND, standby is turned on (output off). 2. Muting Muting is turned off (output on) when a signal of 3.5 V or 0.2 m A is impressed at pin 10. When pin 10 is open or connected to GND, muting is turned on (output off). 3.
