HA13150A Datasheet | Hitachi Semiconductor

Description HA13150A is a four-channel BTL amplifier IC designed for car audio, featuring high output and low distortion, and applicable to digital audio equipment. It provides 21 W output per channel, with a 14.4 V power supply and at 10% distortion. Functions - Built-in standby circuit - Built-in muting circuit - Built-in protection circuits (surge, TSD, and ASO) Features - - - - - Requires few external parts Low distortion (total harmonic distortion = 0.01% at 3 W) Low noise (at Rg = 620 Ω, noise is 0.15 m V (muting off) or 0.1 m V (muting on)) Popping noise minimized Highly reliable current-limiting ASO protector keeps speakers safe from all kinds of trouble. Reliability is further enhanced by a fast-acting thermal shutdown protection circuit with on/off hysteresis.
