The AD7796/AD7797 are complete, analog front ends for highprecision, bridge sensor applications such as weigh scales. TheAD7796/AD7797 contain a Σ-∆ ADC capable of 16-/24-bitresolution, respectively. The on-chip instrumentation amplifierhas a fixed gain of 128, allowing small amplitude signals such asthose from bridge sensors to be directly interfaced to the ADC.
Each device has one differential input and contains a temperaturesensor that is internally connected to the ADC. This sensor canbe used to perform temperature compensation of the bridge.
The devices can be operated with the internal clock or an externalclock. The output data rate from the devices is software-programmableand can be varied from 4.17 Hz to 123 Hz.
The AD7796/AD7797 operate with a power supply from 2.7 Vto 5.25 V. Each device consumes a current of 250 µA typical andis housed in a 16-lead TSSOP.
Applications
- Weigh scales
