The TAS5508C is an 8-channel digital pulse-width modulator (PWM) that provides both advanced performance and a high level of system integration. The TAS5508C is designed to interface seamlessly with most audio digital signal processors. The TAS5508C automatically adjusts control configurations in response to clock and data rate changes and idle conditions. This enables the TAS5508C to provide an easy-to-use control interface with relaxed timing requirements.

The TAS5508C can drive eight channels of H-bridge power stages. Texas Instruments H-bridge parts TAS5111, TAS5112, or TAS5182 with FETs are designed to work seamlessly with the TAS5508C. The TAS5508C supports both single-ended or bridge-tied load configurations. The TAS5508C also provides a high-performance, differential output to drive an external, differential-input, analog headphone amplifier (such as the TPA112).

The TAS5508C uses AD modulation operating at a 384-kHz switching rate for 48-, 96-, and 192-kHz data. The 8× oversampling combined with the fifth-order noise shaper provides a broad, flat noise floor and excellent dynamic range from 20 Hz to 20 kHz.

The TAS5508C is a clocked slave-only device. The TAS5508C receives MCLK, SCLK, and LRCLK from other system components. The TAS5508C accepts master clock rates of 128, 192, 256, 384, 512, and 768 Fs. The TAS5508C accepts a 64-Fs bit clock.

The TAS5508C allows for extending the dynamic range by providing a power-supply volume control (PSVC) output signal.
