AD7190 4.8 kHz Ultra-Low Noise 24-Bit Sigma-Delta ADC

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. The device can be configured to have two differentia.
