Texas Instruments TAS5548DCA

The TAS5548 is an 8-channel Digital Pulse Width Modulator (PWM) with Digital Audio Processing and Sample Rate Converter that provides both advanced performance and a high level of system integration. TAS5548 is designed to support DTS-HD specification Blu-ray HTiB applications. The ASRC consists of two separate modules which handle 4 channels each. Therefore, it is possible to support up to two different input sampling rates.

Texas Instruments Power Stages are designed to work seamlessly with the TAS5548. The TAS5548 also provides a high-performance, differential output to drive an external, differential-input, analog headphone amplifier.

The TAS5548 supports AD, BD, and ternary modulation operating at a 384-kHz switching rate for 48-, 96-, and 192-kHz data. The external crystal used must be 12.288 MHz. The TAS5548 also features power-supply-volume-control (PSVC), which improves dynamic range at lower power level and can be used as part of a Class G power supply when used with closed-loop PWM input power stages.
