REF02CS-REEL7

Overview

The REF02CSZ-REEL7 is a precision series voltage reference IC manufactured by Analog Devices Inc., housed in an 8-SOIC surface-mount package. It provides a fixed output voltage of 5V with an initial accuracy tolerance of ±1%. The device operates within an input voltage range of 8V to 36V and draws a supply current of 1.6mA. Key electrical characteristics include a temperature coefficient of 65ppm/°C and low noise performance of 15µVp-p from 0.1Hz to 10Hz. It supports a maximum output current of 10mA and functions reliably across a temperature range of -40°C to +85°C.

Feature Summary

• Delivers a stable 5V fixed output voltage suitable for precision applications
• Features low noise performance with 15µVp-p specification in the 0.1Hz to 10Hz band
• Supports wide input voltage operation ranging from 8V to 36V

Applications

• Precision analog-to-digital converter (ADC) reference sources
• Data acquisition systems requiring stable voltage references
• Industrial control circuits needing accurate voltage benchmarks

Procurement Notes

Verify that the specific part number suffix matches the required package type, as the REEL7 designation indicates tape and reel packaging. Confirm compatibility with the target PCB footprint for the 8-SOIC form factor. Ensure the design accounts for the specified input voltage range and thermal dissipation requirements within the operating temperature limits. Cross-reference the manufacturer's latest datasheet for any recent pinout or electrical specification updates before finalizing the bill of materials.

Selection Notes

Select this component when a fixed 5V reference with ±1% accuracy is required for surface-mount designs. It is appropriate for applications where low noise and wide input voltage flexibility are prioritized over ultra-low temperature coefficients. Consider the 10mA output current capability to ensure it meets the load requirements of the downstream circuitry without exceeding specifications.
