1.5V / 15mW dual power amplifier
BA5152F
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 nega-
tive-feedback components are not required.
FApplications
1.5V headphone Hi-Fi stereos
FFeatures
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.
