Product Summary
The AD7793BRUZ is a low power, complete analog 16/24-bit Sigma-Delta ADC with low-noise in-amp and embedded reference for low frequency measurement applications. The AD7793BRUZ contains a low noise 16/24-bit Σ-Δ ADC with three differential analog inputs. The on-chip low noise instrumentation amplifier means that signals of small amplitude can be interfaced directly to the ADC. With a gain setting of 64, the rms noise is 80 nV when the update rate equals 16.6 Hz. The AD7793BRUZ contains a precision low noise, low drift internal bandgap reference for absolute measurements. An external reference can also be used if ratiometric measurements are required.
