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. 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.
●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/ 4Ω@ 14.4 V, 1 kHz, 10 % THD
●■ Max. output power 4x72 W/2Ω
●■ 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 independent front/rear) and diagnostics pin
●■ CMOS compatible enable pin (3.3/5 V)
●■ Full fault protection
●■ Four independent short circuit protections
●■ Thermal protection (four levels)
●■ ESD protection
