High-Performance Applications
The TAS5508B is an 8-channel digital pulse-width modulator (PWM) that provides both advanced
performance and a high level of system integration. The TAS5508B is designed to interface seamlessly
with most audio digital signal processors. The TAS5508B automatically adjusts control configurations in
response to clock and data rate changes and idle conditions. This enables the TAS5508B to provide an
easy-to-use control interface with relaxed timing requirements.
The TAS5508B can drive eight channels of H-bridge power stages. Texas Instruments power stage parts
TAS5111, TAS5112, or TAS5182 with FETs are designed to work seamlessly with the TAS5508B. The
TAS5508B supports either the single-ended or bridge-tied-load configuration. The TAS5508B also
provides a high-performance, differential output to drive an external, differential-input, analog headphone
amplifier (such as the TPA112).
The TAS5508B 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 TAS5508B is a clocked slave-only device. The TAS5508B receives MCLK, SCLK, and LRCLK from
other system components. The TAS5508B accepts master clock rates of 128, 192, 256, 384, 512, and
768 fS. The TAS5508B accepts a 64-fS bit clock.
The TAS5508B allows for extending the dynamic range by providing a power-supply, volume-control
(PSVC) output signal.
