Support for Enhanced Dynamic Range in
Adjustable Modulation Limit
High-Performance Applications
The TAS5518C is an 8-channel digital pulse-width modulator (PWM) that provides both advanced
performance and a high level of system integration. The TAS5518C is designed to interface seamlessly
with most audio digital signal processors. The TAS5518C automatically adjusts control configurations in
response to clock and data rate changes and idle conditions. This enables the TAS5518C to provide an
easy-to-use control interface with relaxed timing requirements.
The TAS5518C 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 TAS5518C. The
TAS5518C supports either the single-ended or bridge-tied-load configuration. The TAS5518C also
provides a high-performance, differential output to drive an external, differential-input, analog headphone
amplifier (such as the TPA112).
The TAS5518C 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 TAS5518C is a clocked slave-only device. The TAS5518C receives MCLK, SCLK, and LRCLK from
other system components. The TAS5518C accepts master clock rates of 128, 192, 256, 384, 512, and
768 fS. The TAS5518C accepts a 64-fS bit clock.
The TAS5518C allows for extending the dynamic range by providing a power-supply, volume-control
(PSVC) output signal.
