Description

This TI Designs, Precision Verified design implements an analog input module for industrial voltages, currents, and temperature sensors.  For industrial outputs, the possible input ranges include: 4-20 mA, 0-20 mA, +/-25 mA, 0-5 V, 0-10 V, +/-5 V, +/-10 V. The design includes conditioning and level-shift circuitry which converts the large industrial outputs into a proper input range for a +5V delta-sigma ADC. The ADC has features to directly acquire information from the RTD and thermocouple sensors over their full temperature range.

Features
  • TI Designs - Precision: Verified Design includes Theory, Component Selection, TINA-TI Simulation, PCB Schematic & Layout, Bill of Materials, and Measured Performance.
  • Voltage Input Range:  +/-10V, 0-10V, +/-5V, 0-5V
  • Current Input Range:  +/-24mA, 0-20mA, 4-20mA
  • 3-Wire RTD Temperature Range:  -200 - 850°C
  • Thermocouple Range:  -210 - 1190°C
  • Thermocouple Cold Junction Compensation Range:  0 - 50°C
