TAS5508C 8 通道 PWM 处理器
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
