TC14433AEJG

ADCs/DACs - Special Purpose Overview

The TC14433AEJG 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 operates with a wide supply range of ±4.5V to ±8V and supports full-scale voltage ranges from 199.9 millivolts to 1.999 volts. It achieves an accuracy of ±0.05% of reading plus one count, with up to 25 conversions per second.

ADCs/DACs - Special Purpose Procurement Notes

Verify the package type matches the required application, as the TC14433 family includes multiple options such as PLCC, SOIC, and PDIP. Confirm the temperature grade; the AEJG suffix indicates a wide industrial temperature range (-40°C to +85°C). Ensure that the specific ordering suffix aligns with the desired pinout and environmental specifications before finalizing procurement.

ADCs/DACs - Special Purpose Selection Notes

Select the TC14433AEJG when a ceramic DIP package is required for through-hole mounting in industrial environments. The 'A' suffix denotes improved performance over the standard TC14433, including lower power consumption and specified rollover error within one count. Choose this variant over plastic packages if higher thermal stability or hermetic sealing characteristics are necessary for the design.

ADCs/DACs - Special Purpose Part Context

The TC14433AEJG belongs to the TC14433/A family of 3-1/2 digit A/D converters. It is functionally equivalent to other variants like the TC14433AELI (PLCC) and TC14433AEPG (PDIP), differing primarily in package style. All family members share the same core electrical characteristics, pin functions, and conversion algorithms, allowing for flexible layout choices while maintaining identical performance metrics.
