General Description
The CS5566 is a single-channel, 24-bit analog-to-digital
converter capable of 5 kSps conversion rate. The input
accepts a fully differential analog input signal. On-chip
buffers provide high input impedance for both the AIN in-
puts and the VREF+ input. This significantly reduces the
drive requirements of signal sources and reduces errors
due to source impedances. The CS5566 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 conver-
sion. 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-refer-
enced 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 log-
ic operating from 1.8, 2.5, or 3.3 V.
