Product Description

The AD7797BRUZ is a 24-bit Low Power Sigma-Delta (Σ-Δ) ADC for high precision bridge sensor applications such as weigh scales. It contains Σ-Δ ADC capable of 24-bit resolution. 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. Each part has one differential input and contains a temperature sensor that is internally connected to the ADC. This sensor can be used to perform temperature compensation of the bridge. ADC can be operated with either the internal clock or an external clock. The output data rate from the part is software programmable and can be varied from 4.17Hz to 123Hz. The complete analogue front ends device operates with a power supply from 2.7 to 5.25V.
