FDA803Q

1 channel class D digital input automotive power amplifier with diagnostics,

wide voltage operation range for car audio and telematic

Data brief

 2 Ω loads driving

 Amplitude limiter function (configurable

through I C)

 I C bus diagnostics:

– Short to V /GND

– Short load and open load detection (also in

play mode)

GAPGPS03203

VFQFPN 7x7x1.0 48L

(Exposed pad down)

– Four thermal warnings

 DC offset detector (also in play) and 'hot spot'

detection

Features

 Clipping detector

 AEC-Q100 qualified

 Integrated thermal protection

 Integrated 108 dB D/A conversion

 Legacy mode ('no I C' mode), 4 configurable

settings

 I S and TDM digital input (4/8/16CH TDM)

 Short circuit and ESD integrated protections

 Package: VFQFPN48 exposed pad down

 Input sampling frequency: 44.1 kHz, 48 kHz,

96 kHz, 192 kHz

 Full I C bus driving (3.3/1.8 V)
