TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic
TA7376P
Audio Power Amplifier
TA7376P
The TA7376P is dual audio power amplifier for portable
products.
Features
· Low operating supply voltage: VCC = 1.8~6V (Ta = 25°C)
· Low quiescent current: ICCQ = 5.3mA
(VCC = 4.5V)
· Including ripple filter circuit: RR = −42dB
(CRIP = 10µF, fr = 100Hz)
· Voltage gain: GV = 39.5dB (typ.)
· Very few external parts and small package. (SIP−9pin)
Weight: 0.92g (typ.)
