Closed-Loop I2S Audio Amplifiers
- Created: Friday, 18 October 2013
Texas Instruments (TI) (Dallas, TX) has introduced a family of four digital-input, closed-loop I2S amplifiers for mid-power stereo audio applications including TVs, soundbars, portable docking stations, Bluetooth® speakers, and aftermarket automotive audio products. The TAS5760xx devices feature high switching frequency, allowing designers to use smaller output filter components to reduce overall solution size and bill of materials (BOM) cost. They stream 20W continuous power per channel without a heatsink, and deliver superior performance specifications, including THD+N of 0.03 percent at 1 W, crosstalk of -92 dB, and 66-uV idle channel noise.
