Introduction
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. The TAS5028 also provides a high performance
differential output to drive an external differential input analog headphone amplifier (such as the TPA112).
The TAS5028’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 5th order noise shaper provides a broad flat noise floor and excellent
dynamic range from 20 Hz to 20 kHz.
The TAS5028 is clock slave only device. The TAS5028 receives MCLK, SCLK and LRCLK from other system
components. The TAS5028 accepts master clock rates of 128, 192, 256, 384, 512, and 768 Fs. The TAS5028
accepts a 64-Fs bit clock.
