REF01CESA+

Overview

The REF01CESA+ is a precision series voltage reference providing a fixed 10V output. It operates with an input voltage range of 13V to 30V and draws a quiescent supply current of 1.6mA. The device features a maximum temperature coefficient of 65ppm/°C and an initial accuracy tolerance of ±1%. It supports a maximum load current of 21mA and includes short-circuit protection. The component is housed in an 8-SOIC package and functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Provides a stable, fixed 10V reference output suitable for high-precision analog circuits.
• Includes internal short-circuit protection for indefinite duration without damage.
• Features a trim terminal allowing output adjustment over a ±6% range with minimal impact on temperature stability.

Applications

• Analog-to-Digital Converters
• Digital-to-Analog Converters
• Precision Calibration Standards

Procurement Notes

Verify the specific suffix 'CESA+' against official manufacturer documentation to confirm the industrial temperature grade (-40°C to +85°C) and SOIC package type. Ensure compatibility with single-supply operation requirements between 13V and 30V. Cross-reference datasheet specifications for line regulation and load current limits before finalizing procurement to match system constraints.

Selection Notes

Select this component when a fixed 10V reference is required for industrial environments. The 65ppm/°C temperature coefficient defines its precision class compared to lower drift alternatives. Verify that the 1.6mA quiescent current fits power budgets and that the 21mA load capability meets downstream circuit demands. Confirm the 8-SOIC footprint aligns with PCB layout constraints.

Part Context

This part belongs to the REF01/REF02 family of industry-standard precision voltage references manufactured by Analog Devices Inc./Maxim Integrated. The REF01 variant specifically delivers a 10V output, whereas the REF02 provides 5V. The CESA designation indicates the extended temperature range and surface-mount packaging configuration within this product line.
