TC14433/A  
3-1/2 Digit, Analog-to-Digital Converter  
Features:  
Description  
• 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  
The TC14433 is a low-power, high-performance,  
monolithic CMOS 3-1/2 digit A/D converter. The  
TC14433 combines both analog and digital circuits on  
a single IC, thus minimizing the number of external  
components.  
• Single Positive Voltage Reference  
• Auto-Polarity and Auto-Zero  
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.  
• Overrange and Underrange Signals Available  
• Operates in Auto-Ranging Circuits  
• Uses On-Chip System Clock or External Clock  
• Wide Supply Range: ±4.5V to ±8V  
The TC14433A features improved performance over  
the industry standard TC14433. Rollover, which is the  
measurement of identical positive and negative  
signals, is specified 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  
The TC14433/A is available in 24-Pin PDIP, 24-Pin  
SOIC (TC14433 device only), and 28-Pin PLCC  
packages.
