Cirrus Logic Inc. CS5566-ISZ

Description
The CS5566 is a single-channel, 24-bit analog-to-digital converter (ADC) with a conversion rate of 5 kSps. It features a fully differential analog input with on-chip buffers for high input impedance. The ADC uses a low-latency digital filter architecture that settles to full accuracy in one conversion. The 24-bit data output is in serial form, with the serial port acting as either a master or a slave. The converter supports bipolar, ground-referenced signals when operated from ±2.5V analog supplies and can operate from an analog supply of 0-5V or ±2.5V. The digital interface supports standard logic operating from 1.8, 2.5, or 3.3V.
