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
, 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.

Point of Application Board Design
1. Notes on Application board's pattern design
For increasing stability, the connected line of V
CC
and OUTGND is better to be made wider and
lower impedance.
For increasing stability, it is better to place the capacitor between V
CC
and GND (0.1 F) close to
IC.
For increasing stability, it is better to place C1 to C8 and R1 to R8, which are for stopping
oscillation, close to IC.
It is better to place the grounding of resistor (Rg), between input line and ground, close to INGND
(Pin 12) because if OUTGND is connected to the line between Rg and INGND, THD will become
worse due to current from OUTGND.

2. How to reduce the popping noise by Muting circuit
At normal operating circuit, Muting circuit operates at high speed under 1 s.
In case popping noise becomes a problem, it is possible to reduce the popping noise by connecting
capacitor, which determines the switching time constant, between pin 10 and GND. (Following
figure 2)
We recommend value of capacitor greater then 1 F.
Also transitional popping noise can be reduced sharply by muting before V
CC
and Standby are
ON/OFF.
