TAS5508A
8-Channel Digital Audio PWM Processor
SLES119A – FEBRUARY 2004 – REVISED JULY 2009

– Power-Supply Volume Control (PSVC)
Support for Enhanced Dynamic Range in
1.2
Overview
The TAS5508A is an 8-channel digital pulse-width modulator (PWM) that provides both advanced
performance and a high level of system integration. The TAS5508A is designed to interface seamlessly
with most audio digital signal processors. The TAS5508A automatically adjusts control configurations in
response to clock and data rate changes and idle conditions. This enables the TAS5508A to provide an
easy-to-use control interface with relaxed timing requirements.
The TAS5508A can drive eight channels of H-bridge power stages. Texas Instruments H-bridge parts
TAS5111, TAS5112, or TAS5182 with FETs are designed to work seamlessly with the TAS5508A. The
TAS5508A supports both single-ended or bridge-tied load configurations. The TAS5508A also provides a
high-performance, differential output to drive an external, differential-input, analog headphone amplifier
(such as the TPA112).
The TAS5508A uses AD modulation operating at a 384-kHz switching rate for 48-, 96-, and 192-kHz data.
The 8 oversampling combined with the fifth-order noise shaper provides a broad, flat noise floor and
excellent dynamic range from 20 Hz to 20 kHz.
The TAS5508A is a clocked slave-only device. The TAS5508A receives MCLK, SCLK, and LRCLK from
other system components. The TAS5508A accepts master clock rates of 128, 192, 256, 384, 512, and
768 f
. The TAS5508A accepts a 64-f
S
The TAS5508A allows for extending the dynamic range by providing a power-supply volume control
(PSVC) output signal.
