Description

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-, 44.1-, 48-, 88.2-, 96-, 176.4-, and 192-kHz data. The 8× oversampling, combined with the 4th-order noise shaper, provides a broad, flat noise floor and excellent dynamic range from 20 Hz to 20 kHz.

The TAS5086 is only an I²C slave device, which always receives MCLK, SCLK, and LRCLK from other system components. The TAS5086 accepts clock rates of 128, 192, 256, 384, and 512 f_S. The TAS5086 accepts a 64-f_S master clock for 176.4-kHz and 192-kHz data.

The TAS5086 accepts a 64-f_S bit clock for all data rates. The TAS5086 also can accept a 48-f_S SCLK rate for MCLK ratios of 192 f_S and 384 f_S.

The TAS5086 is composed of five functional blocks.
