REF02CESA+

Overview

The REF02CESA+ is a precision voltage reference providing a stable +5V output. It operates within an extended temperature range of -40°C to +85°C and features a maximum temperature coefficient of 65ppm/°C with an initial error of ±50mV. The device utilizes an 8-pin Small Outline (SO) package. It supports single-supply operation over an input voltage range of 7V to 33V, drawing a low quiescent current of 1mA. Additionally, the REF02 includes a dedicated TEMP pin that outputs a voltage linearly proportional to temperature.

Feature Summary

• Provides a pretrimmed +5V output with adjustable range capability
• Includes a linear temperature transducer output on the TEMP pin
• Features short-circuit protection for indefinite duration

Applications

• Analog-to-Digital Converters
• Digital-to-Analog Converters
• Precision Temperature Transducers
• Threshold Detectors

Procurement Notes

Verify the component matches the specific extended temperature grade (-40°C to +85°C) and SOIC package configuration required for your design. Confirm lead-free status via the '+' suffix in the part number. Ensure compatibility with existing system power supply ranges and thermal management requirements before finalizing procurement specifications.

Selection Notes

Select this component when a stable +5V reference is needed alongside integrated temperature sensing capabilities. The REF02 differs from the REF01 by offering the TEMP pin and a lower nominal output voltage. Consider the 65ppm/°C temperature coefficient limit for high-precision applications requiring extended industrial temperature operation.

Part Context

The REF02CESA+ belongs to the industry-standard REF01/REF02 family of precision voltage references manufactured by Analog Devices Inc./Maxim Integrated. This series is designed for applications requiring high stability and low noise. The CESA variant specifically denotes the commercial extended temperature range and surface-mount packaging option within the broader product lineup.

Replacement Considerations

For new designs, consult the MAX6035 or MAX6143 data sheets as recommended alternatives. Verify pinout compatibility and electrical parameter alignment if substituting other REF02 variants or different manufacturer offerings.
