Overview
The REF02CS is a precision voltage reference from Analog Devices, providing a stable 5.0 V output with an initial accuracy of ±0.3% maximum and a temperature coefficient of 8.5 ppm/°C maximum. It operates within a supply voltage range of 7 V to 36 V and draws a quiescent current of 1.4 mA maximum. The device features a low noise profile of 15 µV p-p (0.1 Hz to 10 Hz) and can source up to 10 mA of load current. Packaged in an 8-lead SOIC, it supports single-supply operation and includes a TEMP pin for temperature monitoring.
Feature Summary
- Provides a stable 5.0 V output with high initial accuracy and excellent temperature stability.
- Features a dedicated temperature sensor output at the TEMP pin for system monitoring.
- Includes a TRIM terminal allowing for fine adjustment of the output voltage.
- Capable of driving loads up to 10 mA while maintaining regulation.
Applications
- Precision data systems
- High resolution converters
- Industrial process control systems
Procurement Notes
Verify the specific grade suffix against the ordering guide to confirm performance parameters such as temperature range and accuracy. Ensure the package type matches the design requirements. Confirm availability status as commercial-grade products may have limited distribution channels compared to military-grade variants.
Selection Notes
Select this component when a fixed 5.0 V reference with high precision is required. Consider the ADR02 series for newer designs offering higher accuracy and wider temperature ranges. Verify that the input voltage remains within the specified 7 V to 36 V range for optimal line regulation.
Part Context
The REF02CS belongs to the REF01/REF02/REF03 series of precision voltage references. These devices utilize a standard band gap design with laser trimming to enhance accuracy and drift performance. The series is available in multiple packages including SOIC, PDIP, CERDIP, and TO-99, catering to various application constraints.
Replacement Considerations
Public confirmed substitute part numbers: REF02CSZ, REF02CS#REEL, REF02CS#REELTR.
FAQ
What is the function of the TEMP pin?
The TEMP pin provides an unbuffered output directly from the band gap core, varying linearly with temperature at approximately 1.96 mV/°C for monitoring purposes.
How does the TRIM terminal work?
The TRIM terminal allows for fine adjustment of the output voltage up or down from the nominal value using an external potentiometer network, without significantly affecting temperature performance.
