REF01CP+

Overview

The REF01CP+ is a precision series voltage reference providing a fixed 10V output. It operates with an input voltage range of 13V to 33V and draws a quiescent supply current of 1mA to 1.6mA. The device features a maximum temperature coefficient of 65ppm/°C and an initial accuracy of ±100mV. It supports a load current up to 21mA and includes short-circuit protection. The component is housed in an 8-pin Plastic DIP package and functions within a temperature range of 0°C to +70°C.

Feature Summary

• Provides a stable 10V reference output suitable for high-precision analog circuits
• Includes a trim terminal allowing output adjustment over a ±6% range
• Features built-in short-circuit protection for indefinite duration
• Offers low noise performance and minimal impact on stability during trimming

Applications

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

Procurement Notes

Verify the specific suffix 'CP+' corresponds to the 8-pin Plastic DIP package variant when sourcing. Confirm that the lead-free designation aligns with project requirements. Ensure the operating environment remains within the specified 0°C to +70°C range to maintain guaranteed electrical characteristics. Cross-reference pin configurations to avoid compatibility issues with existing PCB layouts.

Selection Notes

Select this component when a fixed 10V reference is required without the need for temperature sensing capabilities found in the REF02 variant. Consider the ±6% trim range if system-level calibration is necessary. Evaluate the 65ppm/°C temperature coefficient against stricter stability requirements; higher precision options like the REF01E or REF01H may be preferred for tighter thermal constraints.

Part Context

The REF01CP+ 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 stable, accurate voltage sources. The REF01 specifically provides a 10V output, distinguishing it from the 5V REF02 model which also offers a dedicated temperature voltage output pin.

Replacement Considerations

For designs requiring improved temperature stability, consider the REF01EP+ (8.5ppm/°C) or REF01HP+ (25ppm/°C). For surface-mount implementations, the REF01CSA+ serves as the SOIC package equivalent. New designs should also evaluate the MAX6035 or MAX6143 data sheets as recommended alternatives.
