Device Overview

Summary

The TC14433 is a low power, high-performance, monolithic CMOS 3½ digit A/D converter. The TC14433 combines both analog and digital circuits on a single IC, thus minimizing the number of external components. This dual-slope A/D converter provides automatic polarity and zero correction with the addition of two external resistors and two capacitors. The full-scale voltage range of this ratiometric IC extends from 199.9 millivolts to 1.999 volts. The TC14433 can operate over a wide range of power supply voltages, including batteries and standard 5-volt supplies.
