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

• Z_IN> 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.
