Introduction
The TAS5518 is an eight channel digital pulse width a modulator (PWM) that provides superior dynamic range
performance and a high level of system integration. The typical dynamic range in a well-designed system is
110 dB and the power supply volume control (PSVC) feature provides up to 24 dB of additional dynamic range
at normal listening levels.
The TAS5518 is designed to interface seamlessly with most audio digital signal processors. This device
automatically adjusts control configurations in response to clock and data rate changes and idle conditions.
This enables the TAS5518 to provide an easy to use control interface with relaxed timing requirements.
The TAS5518 can drive eight channels of H-bridge power stages. Texas Instruments H-bridge devices
TAS5111, TAS5112, and TAS5182 + FETs are designed to work seamlessly with the TAS5518. The TAS5518
supports both single-ended or bridge-tied load configurations. It also provides a high-performance differential
output to drive an external differential input analog headphone amplifier (such as the TPA112).
The TAS5518 uses an AD modulation operating at a 384-kHz switching rate for 48-, 96-, and 192-kHz data.
The 8x over sampling, combined with a 5th-order noise shaper, provides a broad flat noise floor and excellent
dynamic range from 20 Hz to 20 kHz.
The TAS5518 is a clock slave-only device. It receives MCLK, SCLK, and LRCLK from other system
components. It accepts master clock rates of 128, 192, 256, 384, 512, and 768 Fs and a 64-Fs bit clock.
