Description
3-Channel, Low Noise, Low Power, 20-Bit ∑-Δ ADC with On-Chip In-Amp and Reference AD7785 .
Features
* Up to 20 bits effective resolution RMS noise 40 nV @ 4.17 Hz 85 nV @ 16.7 Hz Current: 400 μA typical Power-down: 1 μA maximum Low noise programmable gain instrumentation amp Band gap reference with 4 ppm/°C drift typical Update rate: 4.17 Hz to 470 Hz 3 differential inputs Internal clock oscillatorApplications
* The AD7785 contains a low noise 20-bit ∑-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 40 nV when the update rate equals 4.17 Hz.AD7785 Distributors
