CS5560-ISZ(2009) Datasheet PDF - Cirrus Logic

General Description
The CS5560 is a single-channel, 24-bit analog-to-digital converter capable of 50 kSps conversion rate. The input accepts a fully differential analog input signal. On-chip buffers provide high input impedance for both the AIN inputs and the VREF+ input. This significantly reduces the drive requirements of signal sources and reduces errors due to source impedances. The CS5560 is a delta-sigma converter capable of switching multiple input channels at a high rate with no loss in throughput. The ADC uses a low-latency digital filter architecture.
