The BA3632K is a dual-channel pre / power system IC designed for 1.5V headphone stereos. There is no need for DC/DC conversion, and the system can operate off a single battery. The IC draws low current (ICC = 2.6mA) to allow long set life.

Features
1) Dual pre-amplifiers with auto reverse compatibility.
2) Dual power amplifiers.
3) Bass boost circuit (variable bass boost).
4) AMS circuit (on chip comparator).
5) Ripple filter.
6) Low power consumption (ICC = 6.8mA, 0.5W
2ch, RL = 32Ω).

Applications
    1.5V headphone stereos.
