TAS5086 8 通道数字音频 PWM 处理器

The TAS5086 is a six-channel digital pulse-width modulator (PWM) that provides both advanced performance and a high level of system integration. The TAS5086 is designed to interface seamlessly with most audio digital signal processors and MPEG decoders, accepting a wide range of input data and clock formats.

The TAS5086 drives six channels of speakers in either single-ended or bridge-tied load configurations that accept a 1N + 1 interface format. The TAS5086 also supports 2N + 1 power stages with the use of some external logic (e.g., TAS5112). Stereo line out in I2S format is available with either a pass-through signal (SDIN4) or an internal downmix.

The TAS5086 uses AD modulation operating at a 384-kHz switching rate for 32-, 44
