TIPD164, Analog Input Module for Industrial Outputs and Temperature Sensors Reference Design. This 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
