TC14433ELI713

ADCs/DACs - Special Purpose Overview

The TC14433ELI713 is a low-power, monolithic CMOS 3-1/2 digit analog-to-digital converter manufactured by Microchip Technology. It integrates dual-slope conversion with auto-polarity and auto-zero correction, requiring only two external resistors and capacitors for operation. The device supports full-scale voltage ranges of 199.9 mV or 1.999 V using a single positive voltage reference. It operates on a wide supply range of ±4.5 V to ±8 V and achieves up to 25 conversions per second. Accuracy is specified at ±0.05% of reading plus one count, with an analog input impedance exceeding 1000 MΩ.

ADCs/DACs - Special Purpose Procurement Notes

Verify the ordering suffix '713' against the manufacturer's official documentation to confirm the specific tape-and-reel packaging configuration. Ensure that the required operating temperature range of -40°C to +85°C aligns with the system design constraints before finalizing procurement.

ADCs/DACs - Special Purpose Selection Notes

Select the TC14433ELI713 when a ratiometric 3-1/2 digit ADC with high input impedance is required. This component is suitable for designs needing ±5 V or ±8 V supplies. For applications demanding lower power consumption than the standard TC14433, consider the TC14433A variant, which typically consumes half the power.

ADCs/DACs - Special Purpose Part Context

This part belongs to the TC14433/A family of 3-1/2 digit A/D converters. The ELI suffix indicates a 28-pin PLCC package with lead-free (Pb-free) manufacturing. The '713' suffix denotes reel packaging. The device is available in other packages including 24-pin PDIP and SOIC.

ADCs/DACs - Special Purpose Replacement Considerations

The TC14433AELI is a pin-compatible alternative offering improved rollover symmetry and lower power consumption. Verify that the specific performance enhancements of the 'A' variant are compatible with the existing circuit design requirements.
