AD7792BRUZ Datasheet

Analog to Digital Converters - ADC


The AD7792BRUZ/AD7793 are low power, low noise, complete analog front ends for high precision measurement applications. The AD7792/AD7793 contain 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 ampli-tude 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. AD7792BRUZ Features • Up to 23 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 oscillator• Simultaneous 50 Hz/60 Hz rejection• Programmable current sources AD7792BRUZ Applications • Thermocouple measurements• RTD measurements• Thermistor measurements• Gas analysis• Industrial process control• Instrumentation• Portable instrumentation• Blood analysis• Smart transmitters• Liquid/gas chromatography• 6-digit DVM
