TC514COI713

Overview

The TC514COI713 is a precision analog front-end device from Microchip Technology, belonging to the TC500/TC510/TC514 family. It features a dual-slope ADC architecture with a maximum resolution of 17 bits plus sign. The component integrates an integrator, zero-crossing comparator, and processor interface logic. Uniquely within the series, it includes an onboard negative power supply converter for single-supply operation and a four-input differential analog multiplexer. Power dissipation is specified at 18 mW, supporting flexible trade-offs between conversion speed and resolution.

Feature Summary

• Dual-slope ADC with up to 17-bit resolution
• Integrated negative power supply converter for single-supply use
• Four-input differential analog multiplexer
• Low power dissipation of 18 mW

Applications

• Precision measurement systems requiring high-resolution analog-to-digital conversion
• Instrumentation utilizing differential input signals via the integrated multiplexer
• Single-supply applications needing onboard voltage inversion

Procurement Notes

Verify the specific suffix '713' against official Microchip documentation to confirm package type and temperature range specifications. Ensure compatibility with the required three-wire processor control interface (A, B, and CMPTR) during system design. Confirm that the 18 mW power dissipation rating aligns with the thermal management capabilities of the intended CDIP16 package environment.

Selection Notes

Select the TC514COI713 when a four-channel differential multiplexer and single-supply capability are required alongside high-precision conversion. Compare against the TC510COI713 if multiplexing is unnecessary, or the TC500A if dual supplies are available and lower power consumption (10 mW) is prioritized over the additional integration features found in the TC514 variant.

Part Context

This part is part of the TC5XX family of precision analog front ends. The family shares a common processor control interface consisting of control inputs A and B, and a zero-crossing comparator output. Devices in this series operate through four conversion phases: auto-zero, integrate, de-integrate, and integrator zero, allowing offset correction and proportional voltage storage on the internal integrator.

Replacement Considerations

The TC510COI713 serves as a functional substitute if the four-input differential analog multiplexer is not required. The TC500A requires dual power supplies but offers improved linearity and lower power dissipation.
