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. T o simplify assembly, the gain is fixed, so external ne ga­tive-feedback components are not required.
