ADCs/DACs - Special Purpose datasheet and documents for TC14433ELI
ADCs/DACs - Special Purpose Overview
The TC14433ELI is a low-power, monolithic CMOS 3-1/2 digit analog-to-digital converter manufactured by Microchip Technology. It integrates both analog and digital circuits to minimize external components. The device operates with a wide supply range of ±4.5V to ±8V and supports full-scale voltage ranges of 199.9 mV or 1.999 V. Key electrical characteristics include an accuracy of ±0.05% of reading plus one count, input impedance exceeding 1000 MΩ, and conversion rates up to 25 per second. It features auto-polarity, auto-zero correction, and overrange/underrange signals.

ADCs/DACs - Special Purpose Procurement Notes
Verify the package type matches the specific application requirements. The TC14433ELI designation indicates a 28-pin PLCC package. Confirm that the system design accommodates the required dual power supply rails within the specified operating temperature range of -40°C to +85°C.
ADCs/DACs - Special Purpose Selection Notes
Select the TC14433ELI for applications requiring high input impedance and ratiometric measurement capabilities. Ensure the external clock resistor (typically 300 kΩ) is selected to achieve the desired conversion rate. Verify that the reference voltage source matches the intended full-scale range of either 2V or 200 mV.
ADCs/DACs - Special Purpose Part Context
The TC14433ELI belongs to the TC14433/A family of 3-1/2 digit A/D converters. This family includes variants such as the TC14433COG in a 24-pin SOIC package and the TC14433AELI713 in a reel-packaged PLCC format. The ELI suffix specifically denotes the 28-pin PLCC package configuration.
ADCs/DACs - Special Purpose Replacement Considerations
The TC14433AELI713 serves as a functional substitute within the same package type. Designers should verify pin compatibility and ensure that any performance differences between the standard TC14433 and the improved TC14433A specifications meet the system requirements.
