General Description

The AD7796/AD7797 are complete, analog front ends for high precision, bridge sensor applications such as weigh scales.

The AD7796/AD7797 contain a Σ-Δ ADC capable of 16-/24-bit resolution, respectively.

The on-chip instrumentation amplifier has a fixed gain of 128, allowing small amplitude signals such as those from bridge sensors to be directly interfaced to the ADC.
