Thông Tin Sản Phẩm
Tổng Quan Sản Phẩm
AD7797 is a complete, analogue front end for high precision, bridge sensor applications such as weigh scales. The AD7797 contain a Σ-∆ ADC capable of 24bit 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. Each device 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. The devices can be operated with the internal clock or an external clock. Typical application includes weigh scales, strain gauges, industrial process control instrumentation and portable instrumentation.
