Single Chip 25 Watt Mono Class-D Audio Power Amplifier Circuit

This class-D audio ability amplifier is acceptable for TV and home stereo set. TDA7882 IC dent provides class-D audio ability amplifier solution. Since this dent has alone address channel, you charge two pieces of this ambit for stereo application. The ability accumulation voltage is flexible, acquire (+-)10V to (+-)25V. This ambit needs a breach accumulation (symmetric ability supply). Here are the capital appearance of this class-D amplifier:





















  • 25W OUTPUT POWER: RL = 8 ohm/4 ohm; THD = 10%
  • HIGH EFFICIENCY
  • WIDE SUPPLY VOLTAGE RANGE (UP TO ±25V)
  • SPLIT SUPPLY
  • OVER-VOLTAGE PROTECTION
  • ST-BY AND MUTE FEATURES
  • SHORT CIRCUIT PROTECTION
  • THERMAL OVERLOAD PROTECTION
