Audio Amp Speaker 1-CH Mono/2-CH Stereo 20.9W Class-AB 48-Pin HTQFP EP T/R, TAS5731PHPR, Texas Instruments

The TAS5731 is a 20-W, efficient, digital-audio stereo power amplifier for driving stereo bridge-tied speakers. One serial data input allows processing of up to two discrete audio channels and seamless integration to most digital audio processors and MPEG decoders. The device accepts a wide range of input data and data rates. A fully programmable data path routes these channels to the internal speaker drivers.The TAS5731 is a slave-only device receiving all clocks from external sources. The TAS5731 operates with a PWM carrier between a 384-kHz switching rate and a 352-kHz switching rate, depending on the input sample rate. Oversampling combined with a fourth-order noise shaper provides a flat noise floor and excellent dynamic range from 20 Hz to 20 kHz.

  • 2-Ch I2S Input; 8-kHz to 48-kHz fS
  • 20-W Stereo, 8 O/18 V (THD+N = 10%)
  • Up to 90% Efficient Operation
  • Wide 8-V to- 21-V Supply Range;
    3.3-V Digital Supply
  • Single-Device 2.1 Support (2 × SE + 1 × BTL)
  • 70-mO RDS(on) Device That Can Support
    2-O SE and 4-O BTL Modes
    • 12 V / 2 O / 8 W With SE mode
    • 12 V / 4 O / 15 W With BTL mode
  • Speaker EQ (8 BQ per Channel), 2× DRCs
  • P2P Compatible With the TAS5727
  • Benefits
    • Direct Connect to Digital Processor
    • High Output Power From a Standard Supply
    • Eliminates Need for Heat Sink
    • Advanced Processing Improves Audio Experience
