The BA5152F is a dual-channel power amplifier designed for 1.5V headphone stereos. The circuit consists of a power supply circuit, mute circuit, bias circuit, and two amplifier circuits. To simplify assembly, the gain is fixed, so external negative-feedback components are not required.

Features
1) High output. POUT = 15mW (RL = 16Ω).
2) Small “pop” noise.
3) Mute circuit terminal provided.
4) Terminals provided for radiation countermeasures.
5) Good ripple rejection ratio.
6) Few external components required.
7) Good low-voltage characteristics.
8) Built-in power switch circuit.

Applications
