TC14433COG713

ADCs/DACs - Special Purpose Overview

The TC14433COG713 is a low-power, high-performance monolithic CMOS 3-1/2 digit Analog-to-Digital Converter manufactured by Microchip Technology. It integrates analog and digital circuits to minimize external components. This dual-slope A/D converter provides automatic polarity and zero correction using only two external resistors and two capacitors. The device supports ratiometric measurements with full-scale voltage ranges extending from 199.9 millivolts to 1.999 volts. It operates over a wide supply range of ±4.5V to ±8V and achieves up to 25 conversions per second.

ADCs/DACs - Special Purpose Feature Summary

• Accuracy of ±0.05% of reading plus or minus one count
• Two selectable voltage ranges: 1.999V and 199.9 mV
• High input impedance exceeding 1000M Ohms
• Auto-polarity and auto-zero correction capabilities

ADCs/DACs - Special Purpose Applications

• Digital Voltmeters
• Digital Panel Meters
• Portable Instruments
• Digital Scales
• MPU Systems

ADCs/DACs - Special Purpose Procurement Notes

Verify the '713' suffix indicates tape-and-reel packaging containing 1000 units in a 13-inch reel. Confirm the 'COG' designation corresponds to the 24-pin SOIC (Wide) package with an operating temperature range of 0°C to +70°C. Ensure compatibility with standard surface-mount assembly processes for this specific package type.

ADCs/DACs - Special Purpose Selection Notes

Select the TC14433COG713 when a surface-mount 24-pin SOIC package is required for designs operating between 0°C and +70°C. Choose this variant over the TC14433A series if the improved rollover error specifications and lower power consumption of the 'A' version are not critical requirements for the application.

ADCs/DACs - Special Purpose Part Context

This component belongs to the TC14433/A family of 3-1/2 digit A/D converters. The base TC14433 model offers standard performance, while the TC14433A variant provides improved linearity and reduced power consumption. The COG suffix specifically identifies the industrial-grade 24-pin SOIC package configuration within this product line.

ADCs/DACs - Special Purpose Replacement Considerations

The TC14433AELI serves as a functional replacement offering improved rollover accuracy and lower power consumption. Substitution requires verifying that the target application can accommodate the 28-pin PLCC package instead of the 24-pin SOIC form factor.
