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. The filter is designed for fast settling and settles to full accuracy in one conversion. The converter's 24-bit data output is in serial form, with the serial port acting as either a master or a slave. The converter is designed to support bipolar, ground-referenced signals when operated from 2.5V analog supplies. The converter can operate from an analog supply of 0-5V or from 2.5V. The digital interface supports standard logic operating from 1.8, 2.5, or 3.3 V.
