Technical content

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 real- ized. High reliability is obtained due to same kinds of pro- tectors built in. Furthermore, ON/OFF is enabled even if power is supplied to power supply pin by stand-by circuit. n Features

  • High output power
  • Low distortion, low noise
  • Low shock noise from power ON/OFF operation
  • Incorporates stand-by circuits
  • Incorporates protection circuits (Temperature, Overcurrent, Load Short, Output – GND Short) AN7164N BTL 47W Audio Power Amplifier Circuit 2 11 12 3 4 8 9 V CC GNDGND Input Circuit Driver Circuit Output Circuit Ripple Filter Protection Over Temp.
