TAS5731M 2 30-W Digital Audio Power Amplifier With DSP and 2.1 Mode1 Features 3 Description
The TAS5731M is a 30-W, efficient, digital-audio1 2-Ch I2S Input; 8-kHz to 48-kHz fS stereo power amplifier for driving stereo bridge-tied 30-W Stereo, 8 /24 V (THD+N = 10%) speakers. One serial data input allows processing of Up to 90% Efficient Operation up to two discrete audio channels and seamless
integration to most digital audio processors and Wide 8-V to- 24-V Supply Range; 3.3-V DigitalMPEG decoders. The device accepts a wide range ofSupplyinput data and data rates. A fully programmable data Single-Device 2.1 Support (2 SE + 1 BTL) path routes these channels to the internal speaker
80-m RDS(on) Device That Can Support 2- SE drivers.and 4- BTL Modes
The TAS5731M is a slave-only device receiving all 12 V, 2 , 8 W With SE mode clocks from external sources. The TAS5731M 12 V, 4 , 15 W With BTL mode operates with a PWM carrier between a 384-kHz
switching rate and a 352-kHz switching rate, Speaker EQ (8 BQ per Channel), 2 DRCsdepending on the input sample rate. Oversampling Pin-to-Pin Compatible With the TAS5727 and combined with a fourth-order noise shaper provides a
TAS5731 flat noise floor and excellent dynamic range from Benefits: 20 Hz to 20 kHz.
