The TAS5504 is a four channel digital pulse width modulator (PWM) that provides both advanced performance and a high level of system integration. The TAS5504 is designed to interface seamlessly with most audio digital signal processors. The TAS5504 automatically adjusts control configurations in response to clock and data rate changes and idle conditions. This enables the TAS5504 to provide an easy to use control interface with relaxed timing requirements.

The TAS5504 can drive four channels of H-bridge power stages. Texas Instruments H-bridge parts TAS5111, TAS5112, or TAS5182 + FETs are designed to work seamlessly with the TAS5504. The TAS5504 supports both single-ended or bridge tied load configurations. The TAS5504 also provides a high performance differential output to drive an external differential input analog headphone amplifier (such as the TPA112).
