It performs sampling, analogto-digital conversion, and anti-alias filtering, generating 24-bit values for both left and right inputs in serial form at sample rates up to 108 k Hz per channel. The CS5343/4 uses a 3rd-order, multi-bit Delta-Sigma modulator followed by a digital filter, which removes the need for an external anti-alias filter. The CS5343/4 also Features a high-impedance sampling network which eliminates costly external ponents such as op-amps. The CS5343/4 is available in a 10-pin TSSOP package for both mercial (-40° to +85° C) and Automotive grades (-40° to +105° C). The CDB5343 Customer Demonstration Board is also available for device evaluation and implementation suggestions. Please refer to the “Ordering Information” on page 19 for plete details. The CS5343/4 is ideal for audio systems requiring wide dynamic range, negligible distortion and low noise, such as set-top boxes, DVD-karaoke players, DVD recorders, A/V receivers, and automotive applications.
