TA7769P Stereo Power Amplifier IC 14V DIP-16

Description

TA7769P Stereo Power Amplifier IC 14V DIP-16 The TA7769P is a compact dual audio power amplifier integrating two matched channels in a single IC. Optimized for portable audio applications, it provides reliable audio output with low distortion and low turn-on pop noise. With a wide operating supply range and modest quiescent current, the TA7769P is suitable for battery-powered equipment such as portable radios, tape recorders, small speaker systems and other consumer audio products. Features: Dual audio power amplifier for portable radio / cassette applications (stereo). Built-in thermal shut-down protection (T.S.D.) to protect the IC from overheating. Soft-clip / small pop noise at power-on designed to minimize power-on pop noises. Wide operating supply range (designed to operate from low voltages typical of portable equipment). Input stage with PNP differential pair + emitter follower allowing DC referencing of the input to ground (eliminates mandatory input coupling capacitor in many cases). Fixed high voltage gain inside the IC (nominal 56.5 dB) gain may be reduced externally by adding a feedback resistor. Anti-oscillation recommendations provided recommended use of polyester film capacitors for certain bypass/stability caps to avoid oscillation. Compact DIP-16 package (suitable for through-hole mounting in consumer portable electronics).
