REF02CPZ

Overview

The REF02CPZ is a precision voltage reference IC from Analog Devices, providing a fixed 5V output with ±0.3% initial accuracy. It operates on a single supply within a 7V to 40V input range and draws a maximum of 1.4mA supply current. The device features an 8-pin ceramic DIP package (CDIP-8) suitable for through-hole mounting. Key electrical characteristics include a maximum temperature coefficient of 8.5 ppm/°C and low noise performance of 15µV p-p. It supports a load current of up to 10mA and functions reliably across a temperature range of -40°C to 85°C.

Feature Summary

• Provides stable 5V output with high initial accuracy and excellent temperature stability
• Operates as a monolithic temperature transducer with linear voltage output
• Features short-circuit protection and requires no external components
• Delivers high load-driving capability with low power consumption

Applications

• Digital-to-Analog Converters (DACs)
• Analog-to-Digital Converters (ADCs)
• Portable instrumentation systems
• Digital voltmeters

Procurement Notes

Verify the specific suffix CPZ indicates an 8-pin ceramic dual in-line package (CDIP). Confirm RoHS compliance status for the specific manufacturing lot, as older CDIP variants may differ. Ensure the supplier provides official documentation confirming the ±0.3% accuracy grade and 8.5 ppm/°C temperature coefficient specifications.

Selection Notes

Select this component when a fixed 5V reference with high precision is required in a through-hole ceramic package. It is suitable for designs needing short-circuit protection and minimal external circuitry. Consider the REF02 series if a temperature transducer function is also beneficial. Verify that the 10mA load current meets the application requirements.

Part Context

The REF02 is part of Analog Devices' precision voltage reference family, alongside the REF01 (10V) and REF03 (2.5V). These devices utilize an improved band gap design to achieve low noise and low current drain. The REF02CPZ specifically denotes the ceramic package variant, offering robustness compared to plastic packages for harsh environments.

Replacement Considerations

Public confirmed substitutes include REF02CSZ and REF02HN8#PBF. Verify pinout compatibility and package dimensions before substitution. Check if the alternative meets the specific ±0.3% accuracy and 8.5 ppm/°C temperature coefficient requirements.
