Low Power, 8-/16-Channel, 31.25 kSPS, 24-Bit, Highly Integrated Sigma-Delta ADC
Manufactured by:

Product Details

The AD7173-8 is a fast settling, highly accurate, low power, 8-/ 16-channel, multiplexed ADC for low bandwidth input signals with integrated input buffers.

Integrated precision, 2.5 V, low drift (3.5 ppm/°C), band gap reference and integrated oscillator.

Eight flexible setups with configurability for output data rate, digital filter mode, offset/gain error correction, reference selection, buffer enables and more.

Sinc5 + sinc1 filter maximizes channel scan rate, and sinc3 filter maximizes resolution and enhanced 50 Hz/60 Hz rejection, with four selectable options to maximize rejection.

Integrated diagnostic features, including CRC, register checksum, temperature sensor, crosspoint multiplexer, burnout currents, and GPIOs/GPOs.

APPLICATIONS

  • Process control: PLC/DCS modules
    Voltage, current, temperature, and pressure measurement
    Flow meters
  • Medical and scientific multichannel instrumentation
  • Seismic instrumentation
  • Chemical analysis instrumentation: chromatography

Product Details

The EVAL-AD7173-8SDZ is a fully featured evaluation kit for the AD7173-8. This board operates in stand alone mode or in conjunction with the System Development Platform, EVAL-SDP-CB1Z . When operated with the System Development Platform software is provided enabling the user to perform detailed analysis of the ADC's performance. This software includes the technical note describing the operation and set up of the evaluation board in standalone operation or when operated with the System Development Platform . When operated in standalone mode the ADZS-BRKOUT-EX3 break out board is recommended for access to various control pins. The SDP Controller board is a separate list item in the ordering guide below (EVAL-SDP-CB1Z). If you have not previously purchased an SDP Controller board, please do so to ensure a full evaluation setup.
