The CS5342 is a complete analog-to-digital converter for digital audio systems. It performs sampling, analog-to-digital conversion and anti-alias filtering, generating 24-bit values for both left and right inputs in serial form at sample rates up to 200 kHz per channel.
The CS5342 uses a 5th order, multi-bit Delta-Sigma modulator followed by digital filtering and decimation, which removes the need for an external anti-alias filter.
The CS5342 is available in a 16-pin TSSOP package in...

The ADS42LB69 is a high-linearity, dual-channel, 16-bit, 250-MSPS, analog-to-digital converter (ADC) supporting DDR and QDR LVDS output interfaces. The buffered analog input provides uniform input impedance across a wide frequency range while minimizing sample-and-hold glitch energy. A sampling clock divider allows more flexibility for system clock architecture design. The ADS42LB69 provides excellent spurious-free dynamic range (SFDR) over a large input frequency range with low-power...
