REF02CSZ-REEL

Overview

The REF02CSZ-REEL is a precision series voltage reference IC from Analog Devices, providing a fixed 5V output with ±1% initial accuracy. It operates within an input voltage range of 8V to 36V and draws a supply current of 1.6mA. The device features a temperature coefficient of 65ppm/°C and low noise of 15µVp-p (0.1Hz to 10Hz). It supports a maximum load current of 10mA and functions in temperatures from -40°C to 85°C. Packaged in an 8-SOIC surface-mount case.

Feature Summary

• Provides stable 5V output with minimal temperature drift
• Operates on single-supply with wide input voltage range
• Functions as a monolithic temperature transducer
• Short-circuit proof design without external components

Applications

• DACs and ADCs
• Portable instrumentation
• Digital voltmeters

Procurement Notes

Verify the specific suffix REEL indicates tape-and-reel packaging when ordering. Confirm the ±1% tolerance variant matches design requirements, as other accuracy grades exist. Ensure the 8-SOIC package footprint aligns with PCB layout constraints. Check for RoHS3 compliance status if required by environmental regulations.

Selection Notes

Select this component for applications requiring a stable 5V reference with moderate precision. Consider the 65ppm/°C temperature coefficient against stricter stability needs. Evaluate the 1.6mA supply current for power-sensitive designs. Verify that the 10mA output current meets load demands without additional buffering.

Part Context

This part belongs to the REF02 family of precision voltage references. It serves as a cost-effective solution for general-purpose analog circuits. The SOIC package facilitates automated surface-mount assembly. It replaces older through-hole variants while maintaining functional compatibility.
