Design files

Overview

This reference design that is precision verified implements an analog input module for industrial voltages, currents and temperature sensors.  For industrial outputs, the possible input ranges include: 4 to 20 mA, 0 to 20 mA, +/-25 mA, 0 to 5 V, 0 to 10 V, +/-5 V and +/-10 V. The design includes conditioning and level-shift circuitry which converts 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
  • Includes theory, component selection, TINA-TI simulation, PCB schematic and layout, bill of materials and measured performance
  • Voltage input range:  +/-10 V, 0 to 10V , +/-5V , 0 to 5 V
  • Current input range:  +/-24 mA, 0 to 20 mA, 4 to 20 mA
  • 3-wire RTD temperature range:  -200 to 850°C
  • Thermocouple range:  -210 to 1190°C
  • Thermocouple cold junction compensation range:  0 to 50°C
