AD7783BRUZ

AD7783 is a read-only, pin configured 24bit Ʃ-Δ ADC with excitation current sources. A complete analogue front end for low frequency measurement applications. The 24bit sigma-delta ADC contains one fully differential input channel 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 measurement, weigh scales and portable instrumentation.
