The TAS5504A is a four-channel digital pulse-width modulator (PWM) that provides both advanced performance and a high level of system integration. The TAS5504A is designed to interface seamlessly with most audio digital signal processors. The TAS5504A automatically adjusts control configurations in response to clock and data-rate changes and idle conditions. This enables the TAS5504A to provide an easy-to-use control interface with relaxed timing requirements.

The TAS5504A can drive four channels of H-bridge power stages. Texas Instruments power stages are designed to work seamlessly with the TAS5504A. The TAS5504A supports either the single-ended or bridge-tied-load configuration. The TAS5504A also provides a high-performance differential output to drive an external differential-input analog headphone amplifier, such as the TPA112.

The TAS5504A uses AD modulation operating at a 384-kHz switching rate for 48-, 96-, and
192-kHz data. The 8× oversampling combined with the 5th-order noise shaper provides a broad, flat noise floor and excellent dynamic range from 20 Hz to 20 kHz.

The TAS5504A is a clocked, slave-only device. The TAS5504A receives MCLK, SCLK, and LRCLK from other system components. The TAS5504A accepts master clock rates of 128, 192, 256, 384, 512, and 768 fS. The TAS5504A accepts a 64-fS bit clock.

The TAS5504A allows for extending the dynamic range by providing a power-supply volume-control (PSVC) output signal.
