REF01CESA+T

Overview

The REF01CESA+T is a precision series voltage reference IC manufactured by Analog Devices Inc./Maxim Integrated, housed in an 8-SOIC surface-mount package. It provides a fixed output voltage of 10V with a tolerance of ±1%. The device operates within an input voltage range of 13V to 30V and draws a supply current of 1.6mA. It features a temperature coefficient of 65ppm/°C and exhibits a peak-to-peak noise of 25µV in the 0.1Hz to 10Hz frequency band. The component supports an output current of 21mA and functions reliably across an ambient temperature range of -40°C to 85°C.

Feature Summary

• Delivers a stable 10V fixed output with high initial accuracy.
• Features low-noise performance suitable for sensitive analog circuits.
• Includes internal short-circuit protection without requiring external components.

Applications

• Precision data acquisition systems
• High-resolution analog-to-digital converter references
• Industrial process control instrumentation

Procurement Notes

Verify the specific suffix 'CSA' against official datasheets to confirm the ±1% tolerance grade and commercial temperature range (-40°C to 85°C). Ensure the 8-SOIC package dimensions match the target PCB footprint. Confirm RoHS compliance status as indicated in the manufacturer's documentation before finalizing procurement.

Selection Notes

Select this component when a stable 10V reference is required with moderate precision. Compare the 65ppm/°C temperature coefficient against stricter requirements; if higher stability is needed, consider the REF01HSA variant. Verify that the 13V minimum input voltage aligns with the system power supply rails.

Part Context

This part belongs to the REF01 series of precision voltage references from Maxim Integrated, now part of Analog Devices. The series is designed to provide highly stable voltage outputs for analog signal conditioning. While the REF01 series is established, manufacturers often recommend newer pin-compatible alternatives like the ADR01 series for new designs due to evolving product lifecycles.

Replacement Considerations

The ADR01 series offers pin-compatible replacements with potentially improved specifications. Check specific sub-models like ADR01 for exact tolerance and temperature coefficient matches before substituting.
