KA2206B - 2.3W DUAL AUDIO POWER AMP

Key Features

  • High output power Stereo : PO = 2.3W(Typ) at VCC = 9V, RL = 4Ω . Bridge : PO = 4.7W (Typ) at VCC = 9V, RL = 8Ω.
  • Low switching distortion at high frequency.
  • Small shock noise at the time of power on/off due to a built-in muting circuit.
  • Good ripple rejection due to a built-in ripple filter.
  • Good channel separation.
  • Soft tone at the time of output saturation.
  • Closed loop voltage gain fixed 45dB (Bridge : 51dB) but availability wit.
