Introduction
The TAS5028A is an eight channel digital pulse width modulator (PWM) that provides both advanced
performance and a high level of system integration. The TAS5028A is designed to interface seamlessly with
most audio digital signal processors. The TAS5028A automatically adjusts control configurations in response
to clock and data rate changes and idle conditions. This enables the TAS5028A to provide an easy to use
control interface with relaxed timing requirements.
The TAS5028A 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 TAS5028A. The TAS5028A
supports both single-ended or bridge tied load configurations. The TAS5028A also provides a high
performance differential output to drive an external differential input analog headphone amplifier (such as the
TPA112).
The TAS5028A’s uses an AD modulation operating at a 384-kHz switching rate for 48-, 96-, and 192-kHz data.
The 8x oversampling combined with the 5
th
order noise shaper provides a broad flat noise floor and excellent
dynamic range from 20 Hz to 20 kHz.
The TAS5028A is clock slave only device. The TAS5028A receives MCLK, SCLK and LRCLK from other
system components. The TAS5028A accepts master clock rates of 128, 192, 256, 384, 512, and 768 Fs. The
TAS5028A accepts a 64-Fs bit clock.
