Texas Instruments announces 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 cost.
They stream 20-W continuous power per channel without a heatsink, and deliver the industry’s best performance specifications, including THD+N of 0.03 percent at 1 W, crosstalk of -92 dB, and 66-uV idle channel noise.
The TAS5760xx are available in four pin-compatible, 48-pin versions: the TAS5760MD and TAS5760LD with headphone amplifiers/line drivers, and the TAS5760M and TAS5760L non-headphone versions. For customers that need a smaller footprint, the TAS5760M and TAS5760L are also offered in 9-mm by 6-mm, 32-pin packages.
Key features and benefits of the TAS5760xx:
Tools and support
The TAS5760xxEVM can be purchased today for a suggested retail price of US$99. This evaluation module includes an easy-to-use ControlConsole graphical development suite to simplify the evaluation, configuration and debug of audio products. The ControlConsole’s graphical user interface reduces product development time by enabling quick evaluation of all TAS5760xx stereo amplifier functions. IBIS models are also available for verifying board signal integrity requirements.
Technical support is available on the Audio Forum in the TI E2ECommunity, where engineers can ask questions and get answers from TI experts.
