AD7190BRUZ-REEL

The AD7190BRUZ-REEL from Analog Devices is a high-precision, low-noise 24-bit Sigma-Delta Analog-to-Digital Converter (ADC) designed for demanding measurement applications. It features an on-chip low-noise gain stage, allowing direct interfacing with small amplitude signals.

Key electrical specifications include an output data rate up to 4.8 kSPS, ultralow RMS noise of 8.5 nV/√Hz at a gain of 128, and 16 noise-free bits at 2.4 kHz. The device supports programmable gain from 1 to 128 and offers 2 differential or 4 pseudo-differential input channels. It operates with analog supply voltages from 4.75 V to 5.25 V and digital supply voltages from 2.7 V to 5.25 V, consuming only 6 mA of current.

Designed for versatility, the AD7190BRUZ-REEL operates across a temperature range of -40°C to +105°C. It interfaces via 3-wire serial SPI, QSPI, MICROWIRE, and DSP compatible protocols. The ADC is qualified for automotive applications and is housed in a 24-lead TSSOP package, suitable for various electronic designs.

This ADC is well-suited for applications such as weigh scales, strain gauge transducers, pressure and temperature measurement, chromatography, PLC/DCS analog input modules, and general data acquisition systems requiring high accuracy and low noise.
