  • 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.
    The possibility of having the D/A conversion on board allows the performance to reach an outstanding 115 dB S/N ratio with more than 105 dB of dynamic range.
    This device is equipped with a full diagnostics array that communicates the status of each speaker through the I2C bus. The possibility to control the configuration and behavior of the device by means of the I2C bus makes TDA7801 a very flexible machine.

    Key Features

    • Integrated 110 dB D/A conversion
    • I2S digital input (3.3/1.8 V) with TDM option
    • Selectable input sampling frequency: 44.1 kHz, 48 kHz, 96 kHz, 192 kHz
    • MOSFET power outputs
    • High output power capability 4x28 W/ 4 Ω @ 14.4 V, 1 kHz, 10 % THD
    • Max. output power 4x72 W/2 Ω
    • Full I2C bus driving (3.3/5 V):
      • Independent front/rear soft play/ mute
      • Selectable gain (four levels) for very low noise line-out function
      • I2C bus digital diagnostics (including DC and AC load detection)
    • Two I2C bus addresses and 8-ch TDM mode (only in PowerSO package)
    • Optional non I2C bus mode
    • 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
    • Linear thermal protection (four thermal warnings)
    • ESD protection
