Product Overview

The AD7719BRZ is a complete analog front end sigma-delta Analog-to-digital Converter (ADC) for low frequency measurement applications. It contains two high resolution sigma-delta ADCs, switchable matched excitation current sources, low-side power switches, digital I/O port and temperature sensor. Signals can be converted directly from a transducer without the need for signal conditioning. The 16-bit auxiliary channel has an input signal range of REFIN2 or REFIN2/2. The device operates from a 32kHz crystal with an on-chip PLL generating the required internal operating frequency. The output data rate from the part is software programmable. The peak-to-peak resolution from the part varies with the programmed gain and output data rate.
  • High resolution
  • Factory-calibrated
  • Programmable gain front end
  • Simultaneous sampling and conversion of 2 signal sources
  • Separate reference inputs for each channel
  • 3-wire serial SPI®/QSPI™/MICROWIRE™/DSP compatible Schmitt trigger on SCLK
  • Rail-rail input buffer and PGA
  • On-chip temperature sensor
  • Dual switchable excitation current sources
  • Low-side power switches
  • Reference detect circuit
