TAS5028 8 通道数字音频 PWM 处理器

The TAS5028 is an eight channel digital pulse width modulator (PWM) that provides both advanced performance and a high level of system integration. The TAS5028 is designed to interface seamlessly with most audio digital signal processors. The TAS5028 automatically adjusts control configurations in response to clock and data rate changes and idle conditions. This enables the TAS5028 to provide an easy to use control interface with relaxed timing requirements.

The TAS5028 can drive eight channels of H-bridge power stages. Texas Instruments H-bridge parts TAS5111, TAS5112, or TAS5182 + FETs are designed to work seamlessly with the TAS5028. The TAS5028 supports both single-ended or bridge tied load configurations
