特性 Features

 AEC-Q100 (rev. G) qualified

 Integrated 110 dB D/A conversion

 I2S and TDM digital input (3.3/1.8 V)

 Input sampling frequency: 44.1 kHz, 48 kHz, 96

kHz, 192 kHz

 Full I2C bus driving (3.3/1.8 V) with 8 different

I2C bus addresses

 EMI control for FM/AM compatibility

 EMI compliance evaluated following normative

IEC61967-4 and IEC62132-4

 Low radiation function (LRF)

 Very low quiescent current

 Output low-pass filter included in the feedback

allowing outstanding audio performances

 Wide operating supply range: target 5.5 V-50 V

 MOSFET power outputs allowing high output

power capability under step-up voltage:

– 2 x 120 W /4 Ω @ 35 V, 1 kHz THD = 1

(2 x150 W /4 Ω @ 35 V, 1 kHz THD =10)

– 2 x 140 W /8 Ω @ 50 V, 1 kHz THD = 1

(2 x180 W /8 Ω @ 50 V, 1 kHz THD =10)

– 2 x 270 W /8 Ω @ 50 V max output power

 Operation under standard car battery with high

output power:

– 2 x 22 W /4 Ω @ 14 V, 1 kHz THD = 1

(2 x 28 W /4 Ω @ 14 V, 1 kHz THD = 10)

– 2 x 37 W /2 Ω @ 14 V, 1 kHz THD = 1

(2 x 46 W /2 Ω @ 14 V, 1 kHz THD = 10)

 Possibility to drive 2 Ω loads (until 18 V)

 Independent channel operation

 I2C bus diagnostics:

– Short to Vcc/GND diagnostic (including soft

shorts up to 1k Ω)

– DC load diagnostic

– AC load diagnostic (working both with

internally generated and externally

generated tone)

 Integrated fault protection

 Input and output offset detector

 Clipping detector

 Legacy mode ('no I2C' mode)

 Short circuit and ESD integrated protections

 Package: LQFP64 exposed pad up
