TA7630P

TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic TA7630P Dual. Volume/Balance/Tone (Bass/Treble) DC Control IC The TA7630P is DC controlled dual volume, balance, tone (Bass, treble) IC. As these dual channels are constructed on one chip, this IC is excellent in pair characteristic. It is suitable for automobile stereo, radio cassette, music center, TV multiplex sound receiver and remote controlled applications. Features · Wide power supply voltage range: Single supply VCC (opr) = 8~14 V (Ta = 25°C) Dual supply VCC − VEE (opr) = ±4~±7 V (Ta = 25°C) · Wide volume control range: VR = 80dB (typ.) · Excellent cross talk: C.T. = 70dB (typ.) · Stable for temperature drift. · Wide tone control range Control range: VB = 10dB (typ.) (f = 1 kHz → 100 Hz) VT = 12dB (typ.) (f = 1 kHz → 20 kHz) Block Diagram Weight: 1.00 g (typ.)
