AN7164N
BTL 47W Audio Power Amplifier Circuit
s Overview
The AN7164N is an integrated circuit designed for 47W (VCC = 26.4V, 8Ω) output power amplifier. High power output (BTL 47W), low distortion and low noise are realized. High reliability is obtained due to same kinds of protectors built in. Furthermore, ON/OFF is enabled even if power is supplied to power supply pin by stand-by circuit.
