TA7769P Stereo Power Amplifier 14V IC 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 stereo audio power amplifier (two channels).
- High output power: POUT ≈ 1.0 W at VCC = 6 V, RL = 4 Ω, THD = 10%.
- Wide operating supply range: VCC ≈ 4.5 – 9.0V.
- Built-in thermal shutdown protection.
- Low power-on pop noise and soft-clip characteristic.
- Low quiescent current (CMOS-style low ICCQ).
- Low external parts count.
