Pre / power amplifier for 1.5V headphone stereos
BA3632K
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. FApplications 1.5V headphone stereos. FFeatures 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 RL = 32Ω).
