Additional preview pages of the AD7190 datasheet.

The AD7190 is a low noise, complete analog front end for high precision measurement applications.

It contains a low noise, 24bit ∑-∆ ADC.

The on-chip low noise gain stage means that signals of small amplitude can be interfaced directly to the ADC.

RMS Noise: 7 nV @ 4.7 Hz (gain = 128) 16.5 noise free bits @ 2.4 kHz (gain = 128) Up to 23 noise free bits (gain = 1) Offset drift: 5 nV/°C Gain drift: 2 ppm/°C Specified drift over time Programmable gain (1.
128) Update rate: 4.7 Hz to 4.8 kHz Internal or external clock Simultaneous 50 Hz/60 Hz rejection Four general purpose digital outputs Power supply: 3 V to 5.25 V Current: 6 mA Temperature range:.
40°C to +105°C PLC/DCS Analog Input Modules Data Acquisition Medical and Scie.
