BA3632K

Audio ICs 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). 2ch, FAbsolute maximum ratings (Ta = 25_C) FRecommended operating conditions (Ta = 25_C) 849 Audio ICs FBlock diagram BA3632K 850 Audio ICs FPin descriptions BA3632K 851 Audio ICs BA3632K 852 Audio ICs BA3632K 853 Audio ICs BA3632K 854 Audio ICs BA3632K 855 Audio ICs BA3632K 856 Audio ICs BA3632K FElectrical characteristics (unless otherwise noted, Ta = 25_C, VCC = 1.2V, f= 1kHz, RL = 10kΩ (pre-amplifier), RL = 32Ω (power amplifier), L.BOOST OFF, 0dBm = 0.775Vrms) 857 Audio ICs BA3632K 858 Audio ICs FMeasurement circuit BA3632K 859 Audio ICs FMeasurement circuit switching table BA3632K 860 Audio ICs BA3632K 861 Audio ICs FApplication example BA3632K 862 Audio ICs FElectrical characteristics curves BA3632K 863 Audio ICs BA3632K FExternal dimensions (Unit:s mm) 864 ...
