General Description
The CS5581 is a single-channel, 16-bit analog-to-digital
converter capable of 200 kSps conversion rate. The input
accepts a single-ended analog input signal. On-chip buff-
ers provide high input impedance for both the AIN input
and the VREF+ input. This significantly reduces the drive
requirements of signal sources and reduces errors due to
source impedances. The CS5581 is a delta-sigma convert-
er capable of switching multiple input channels at a high
rate with no loss in throughput. The ADC uses a low-laten-
cy digital filter architecture. The filter is designed for fast
settling and settles to full accuracy in one conversion. The
converter's 16-bit data output is in serial format, with the
serial port acting as either a master or a slave. The convert-
er 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.
