TC7106RCPL

ADCs/DACs - Special Purpose Overview

The TC7106RCPL is a 3½-digit analog-to-digital converter (ADC) manufactured by Microchip Technology, housed in a 40-pin PDIP package. It operates as a single-channel dual-slope integrating ADC with parallel binary output. The device supports a nominal supply voltage range of 5V to 9V and functions within an industrial temperature range of -40°C to +85°C. Key electrical characteristics include a maximum power dissipation of 1.23W and a full-scale input voltage capability of approximately 3.35V. This component is designed for low-power applications, enabling operation from a single 9V battery.

ADCs/DACs - Special Purpose Feature Summary

• 3½-digit resolution with dual-slope integration architecture
• Single-channel analog input with parallel binary output
• Low power consumption suitable for 9V battery operation
• Industrial temperature range (-40°C to +85°C)
• 40-pin Plastic Dual In-line Package (PDIP)

ADCs/DACs - Special Purpose Applications

• Portable digital multimeters
• Precision weighing scales
• Temperature measurement systems using sensor interfaces
• Ratiometric resistance measurement instruments

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'R' against the official Microchip datasheet to confirm the exact temperature grade and package variant, as suffixes often denote regional or environmental specifications. Ensure compatibility with existing PCB footprints for the 40-pin PDIP form factor. Check for moisture sensitivity level requirements during storage and handling prior to soldering.

ADCs/DACs - Special Purpose Selection Notes

Select the TC7106RCPL when a high-resolution 3½-digit conversion is required with minimal external components. It is appropriate for designs needing a single-ended input configuration tied to ground. Compare against the TC7106A series if over-range/under-range signal development features are necessary, as the base TC7106 may lack these specific outputs.

ADCs/DACs - Special Purpose Part Context

The TC7106 belongs to the TC7106 family of LCD drivers and ADCs, widely used in indicating meters. The RCPL variant specifically denotes the PDIP-40 package option within this series. It serves as a cost-effective solution for replacing discrete logic and display driver combinations in portable instrumentation.

ADCs/DACs - Special Purpose Replacement Considerations

Direct pin-compatible replacements include other variants in the TC7106 family such as TC7106CLW or TC7106CKW, provided the package type (PDIP vs PLCC/QFP) and temperature range match the design requirements. Verify that substitute parts support the same 9V battery operation and power dissipation limits.
