Texas Instruments TAS5518CPAGR

Description
The TAS5518C is an 8channel digital pulsewidth modulator (PWM) that provides both advanced performance and a high level of system integration. It 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 easytouse control interface with relaxed timing requirements.
The TAS5518C can drive eight channels of Hbridge 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 singleended or bridgetiedload configuration. The TAS5518C also provides a highperformance, differential output to drive an external, differentialinput, analog headphone amplifier (such as the TPA112).
The TAS5518C uses AD modulation operating at a 384kHz switching rate for 48, 96, and 192kHz data. The 8x oversampling combined with the fifthorder noise shaper provides a broad, flat noise floor and excellent dynamic range from 20 Hz to 20 kHz.
The TAS5518C is a clocked slaveonly 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 64fs bit clock.
The TAS5518C allows for extending the dynamic range by providing a powersupply, volumecontrol (PSVC) output signal.
