Description

The TAS5508B is an 8-channel digital pulse-width modulator (PWM) that provides both advanced performance and a high level of system integration. The TAS5508B is designed to interface seamlessly with most audio digital signal processors. The TAS5508B automatically adjusts control configurations in response to clock and data rate changes and idle conditions. This enables the TAS5508B to provide an easy-to-use control interface with relaxed timing requirements.

The TAS5508B can drive eight channels of H-bridge power stages. Texas Instruments power stage parts TAS5111, TAS5112, or TAS5182 with FETs are designed to work seamlessly with the TAS5508B. The TAS5508B supports either the single-ended or bridge-tied-load configuration.
