Simple three/four-wire serial interface Power Supply Configurations: - Analog: +5V/GND; IO: +1.8V to +3.3V - Analog: ±2.5V; IO: +1.8V to +3.3V Power Consumption: - ADC Input Buffers On: 85 mW - ADC Input Buffers Off: 70 mW 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 in- puts 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 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 CS5560 uses self-calibration to achieve low offset and gain errors. The converter achieves a S/N of 110 dB. Lin- earity is ±0.0007% of full scale. 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. ORDERING INFORMATION: See Ordering Information on page 32.
