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.
