The AD7172-2BRUZ-RL7 is a low power, multiplexed sigma-delta analog-to-digital converter (ADC) from Analog Devices. It features a 24-bit resolution with a maximum output data rate of 31.25 kSPS. The device accepts either 2 fully differential or 4 single-ended input channels via a crosspoint multiplexer, making it suitable for multichannel data acquisition systems.
Key performance highlights include 17.2 noise free bits at 31.25 kSPS and 24 noise free bits at 5 SPS, with an integral nonlinearity of ±2 ppm of full scale. An on-chip 2.5V reference with ±2 ppm/°C drift is included, along with true rail-to-rail buffer inputs. The ADC draws only 1.5 mA typical supply current.
The device operates from supply voltages of 2V to 5.5V (AVDD2/IOVDD) and 3.0V to 5.5V for AVDD1. It communicates via a 3- or 4-wire serial interface compatible with SPI, QSPI, MICROWIRE, and DSP. Housed in a 24-TSSOP surface-mount package, the AD7172-2BRUZ-RL7 is specified over the -40°C to +105°C temperature range.
Typical applications include process control (PLC/DCS modules), temperature and pressure measurement, medical instrumentation, and scientific multichannel analyzers.
The device operates from 2V to 5.5V overall supply, with AVDD1 requiring 3.0V to 5.5V.
It is available in a 24-TSSOP (0.173", 4.40mm Width) surface-mount package.
