Product Description

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
