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.
