Description: 24-BIT SIGMA-DELTA ADC

Features

* AC or DC sensor excitation RMS noise: 8.5 nV at 4.7 Hz (gain = 128) 16 noise-free bits at 2.4 kHz (gain = 128) Up to 22.5 noise-free bits (gain = 1) Offset drift: 5 nV/°C Gain drift: 1 ppm/°C Specified drift over time 2 differential/4 pseudo differential input channels Automatic channel sequencer Pr

Applications

* It contains a low noise, 24-bit sigma-delta (Σ-Δ) analog-to-digital converter (ADC). The on-chip low noise gain stage means that signals of small amplitude can be interfaced directly to the ADC. The AD7195 contains ac excitation, which is used to remove dc-induced offsets from bridge sensors. The d
