10 / 103 page 1.2 Overview TAS5518C 8-Channel Digital Audio PWM Processor SLES238A – SEPTEMBER 2008 – REVISED JULY 2009 www.ti.com 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. Introduction 10 Submit Documentation Feedback Not Recommended For New Designs |
