HA13150A

21 W × 4-Channel BTL Power IC

ADE-207-107 1st. Edition

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 mV (muting off) or 0.1 mV (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.
