High-Performance Applications
Adjustable Modulation Limit
The TAS5508 is an 8-channel digital pulse-width modulator (PWM) that provides both advanced
performance and a high level of system integration. The TAS5508 is designed to interface seamlessly with
most audio digital signal processors. The TAS5508 automatically adjusts control configurations in
response to clock and data rate changes and idle conditions. This enables the TAS5508 to provide an
easy-to-use control interface with relaxed timing requirements.
The TAS5508 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 TAS5508. The
TAS5508 supports both single-ended or bridge-tied load configurations. The TAS5508 also provides a
high-performance, differential output to drive an external, differential-input, analog headphone amplifier
(such as the TPA112).
The TAS5508 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 TAS5508 is a clocked slave-only device. The TAS5508 receives MCLK, SCLK, and LRCLK from
other system components. The TAS5508 accepts master clock rates of 128, 192, 256, 384, 512, and
768 Fs. The TAS5508 accepts a 64-Fs bit clock.
The TAS5508 allows for extending the dynamic range by providing a power-supply volume control (PSVC)
output signal.
