AD7782BRUZ

AD7782 is a read only, pin configured 24bit Ʃ-Δ ADC. A complete analogue front end for low-frequency measurement applications. The 24bit sigma-delta ADC contains two fully differential analogue input channels that can be configured with a gain of 1 or 16 allowing full-scale input signal. Typical application includes sensor measurement, industrial process control, temperature measurement, pressure measurements, weigh scales and portable instrumentation.
