AD7798BRUZ

AD7798 is a low power, low noise, complete analogue front ends for high precision measurement application. This device contains a low noise, 16bit ∑-∆ ADC with three differential analogue inputs. The on-chip, low noise instrumentation amplifier means that signals of small amplitude can be interfaced directly to the ADC. On-chip features include a low-side power switch, reference detect, programmable digital output pins, burnout currents, and an internal clock oscillator. It is widely used in application such as weigh scales, pressure measurement, strain gauge transducers, gas analysis, industrial process control, instrumentation, portable instrumentation, blood analysis, smart transmitters, liquid/gas chromotography, 6-digit DVM etc.
