TC14433  
TC14433A  
3-1/2 DIGIT A/D CONVERTERS  
GENERAL DESCRIPTION  
FEATURES  
The TC14433 is a low power, high-performance, mono-  
lithic CMOS 3-1/2 digit A/D converter. The TC14433 com-  
bines 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. Thefull-scalevoltagerangeofthisratiometricIC  
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.  
■ Accuracy ...................±0.05% of Reading ±1 Count  
■ Two Voltage Ranges .............1.999V and 199.9 mV  
■ Up to 25 Conversions Per Second  
■ ZIN > 1000M Ohms  
■ Single Positive Voltage Reference  
■ Auto-Polarity and Auto-Zero  
■ Overrange and Underrange Signals Available  
■ Operates in Auto-Ranging Circuits  
■ Uses On-Chip System Clock or External Clock  
■ Wide Supply Range .................... e.g., ±4.5V to ±8V  
■ Package Available .................................. 24-Pin DIP  
24-Pin CerDIP, 28-Pin SOIC and 28-Pin PLCC  
The TC14433 will interface with the TC7211A LCD  
display driver.  
The TC14433A features improved performance over  
the industry standard TC14433. Rollover, which is the  
measurement of identical positive and negative signals, is  
guaranteed to have the same reading within one count for  
the TC14433A. Power consumption of the TC14433A is  
typically 4 mW, approximately one-half that of the industry  
standard TC14433.  
APPLICATIONS  
■ Portable Instruments  
■ Digital Voltmeters  
■ Digital Panel Meters  
■ Digital Scales  
■ Digital Thermometers  
■ Remote A/D Sensing Systems  
■ MPU Systems
