特性 Features

 AEC-Q100 qualified

 Integrated 108 dB D/A conversion

 I2S and TDM digital input (4/8/16CH TDM)

 Input sampling frequency: 44.1 kHz, 48 kHz,

96 kHz, 192 kHz

 Full I2C bus driving (3.3/1.8 V)

 CISPR 25 - Class V (Fourth edition)

 Very low quiescent current

 Output lowpass filter included in the feedback

allowing outstanding audio performances

 Wide operating supply range from 3.3 to 18 V,

suitable for car radio, telematics and e-call

 MOSFET power outputs allowing high output

power capability

– 1 x 25 W /4 Ω @ 14.4 V, 1 kHz THD = 1

– 1 x 30 W /4 Ω @ 14.4 V, 1 kHz THD = 10

 2 Ω loads driving

 Power limiting function (configurable through

I2C)

 I2C bus diagnostics:

– Short to VCC/GND

– Short load and open load detection (also in

play mode)

– Four thermal warnings

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

detection

 Clipping detector

 Integrated thermal protection

 Legacy mode ('no I2C' mode), 4 configurable

settings

 Short circuit and ESD integrated protections

 Package: PowerSSO-36 exposed pad down
