The TC14433 is a low-power, high-performance,monolithic CMOS 3-1/2 digit A/D converter. TheTC14433 combines both analog and digital circuits ona single IC, thus minimizing the number of externalcomponents.This dual slope A/D converter provides automaTIcpolarity and zero correcTIon with the addiTIon of twoexternal resistors and two capacitors. The full scalevoltage range of this raTIometric IC extends from 199.9millivolts to 1.999 volts. The TC14433 can operate overa wide range of power supply voltages, includingbatteries and standard 5-volt supplies.The TC14433A features improved performance overthe industry standard TC14433. Rollover, which is themeasurement of identical positive and negativesignals, is specified to have the same reading withinone count for the TC14433A. Power consumption ofthe TC14433A is typically 4 mW, approximately onehalfthat of the industry standard TC14433.The TC14433/A is available in 24-Pin PDIP, 24-PinCERDIP, 24-Pin SOIC (TC14433 device only), and28-Pin PLCC packages.
