TAS5028APAGRG4

Audio Special Purpose Overview

The Texas Instruments TAS5028APAGRG4 is an 8-channel digital audio PWM processor within the PurePath Digital series. It integrates a digital audio processor, input/output crossbar mixers, and PWM modulation logic in a 64-TQFP package (10x10 mm). The device operates on a 3V to 3.6V supply with an industrial temperature range of 0°C to 70°C. It supports serial data formats including I2S, Left Justified, and Right Justified at sample rates from 32kHz to 192kHz. Control is managed via an I2C interface using slave address 0x36.
