TDA7801 - Digital input quad power amplifier

General Description

The TDA7801 is a new BCD technology quad bridge amplifier for car audio applications.

Thanks to the BCD6 technology it is possible to integrate a high performance D/A converter together with powerful MOSFET outputs.

Key Features

  • Datasheet - production data.
  • Two I2C bus addresses and 8-ch TDM mode (only in PowerSO package).
  • Optional non I2C bus mode '!0'03 PowerSO36 (slug-up) '!0'03 Flexiwatt27 (horizontal).
  • Offset detector (play or mute mode).
  • Clipping detector (selectable level) and diagnostics pin.
  • CMOS compatible enable pin (3.3/5 V).
  • Full fault protection.
  • Four independent short circuit protections '!0'03 Flexiwatt27 (vertical) '!0'03 Flexiwatt27 (SMD).
