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

1.5V headphone Hi-Fi stereos
