Introduction
The TAS5504 is a four channel digital pulse width modulator (PWM) that provides both advanced performance
and a high level of system integration. The TAS5504 is designed to interface seamlessly with most audio digital
signal processors. The TAS5504 automatically adjusts control configurations in response to clock and data
rate changes and idle conditions. This enables the TAS5504 to provide an easy to use control interface with
relaxed timing requirements.
The TAS5504 can drive four channels of H-bridge power stages. Texas Instruments H-bridge parts TAS5111,
TAS5112, or TAS5182 + FETs are designed to work seamlessly with the TAS5504. The TAS5504 supports
both single-ended or bridge tied load configurations. The TAS5504 also provides a high performance
differential output to drive an external differential input analog headphone amplifier (such as the TPA112).
The TAS5504’s uses an AD modulation operating at a 384-kHz switching rate for 48-, 96-, and 192-kHz data.
The 8x over sampling combined with the 5th order noise shaper provides a broad flat noise floor and excellent
dynamic range from 20 Hz to 20 kHz.
The TAS5504 is clock slave only device. The TAS5504 receives MCLK, SCLK and LRCLK from other system
components. The TAS5504 accepts master clock rates of 128, 192, 256, 384, 512, and 768 Fs. The TAS5504
accepts a 64-Fs bit clock.
The TAS5504 allows for extending the dynamic range by providing a power supply volume control (PSVC)
output signal.
