REF01CSZ-REEL

Overview

The REF01CSZ-REEL is a series voltage reference IC manufactured by Analog Devices Inc., housed in an 8-SOIC surface-mount package. It provides a fixed 5V output with a tolerance of ±1%. The device operates within an input voltage range of 8V to 36V and draws a supply current of 1.6mA. It features a temperature coefficient of 65ppm/°C and low noise characteristics of 15µVp-p from 0.1Hz to 10Hz. The component supports an operating temperature range of -40°C to +85°C and delivers a maximum output current of 10mA.

Feature Summary

• Provides stable 5V fixed output via series precision reference architecture
• Enables precise calibration through internal trim capabilities
• Operates reliably across extended industrial temperature ranges
• Integrates short-circuit protection for enhanced circuit safety

Applications

• Precision analog-to-digital converter (ADC) reference sources
• Data acquisition system voltage standards
• Industrial instrumentation signal conditioning
• Calibration equipment reference circuits

Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm pinout compatibility and electrical tolerances, as variations exist within the REF01 family. Ensure the procurement channel provides traceable origin data consistent with Analog Devices quality standards. Confirm RoHS compliance status matches project requirements. Validate that the reel packaging specifications align with automated assembly equipment constraints. Cross-reference the part number with current lifecycle notices to ensure availability for production.

Selection Notes

Select this component when a fixed 5V reference is required in a compact surface-mount form factor. The ±1% initial accuracy suits applications demanding moderate precision without external trimming complexity. The 1.6mA supply current offers efficiency advantages over higher consumption alternatives. Consider the 65ppm/°C temperature coefficient for environments with significant thermal fluctuations. Verify that the 10mA load drive capability meets the downstream circuit requirements.

Part Context

This part belongs to the REF01 series of precision voltage references produced by Analog Devices and formerly Maxim Integrated. The series is known for high stability and low noise performance. While the REF01 series is generally not recommended for new designs in favor of the ADR0x family, specific variants like the REF01CSZ-REEL remain available for legacy support and maintenance projects requiring exact functional equivalence.

Replacement Considerations

The ADR01 series offers pin-compatible alternatives with improved specifications. Verify electrical parameter alignment before substitution.
