REF02CESA+T

Overview

The REF02CESA+T is a precision series voltage reference integrated circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It provides a fixed output voltage of 5V with an initial accuracy tolerance of ±1%. The device operates within an input voltage range of 7.3V to 30V and draws a supply current of 1.6mA. It features a temperature coefficient of 15ppm/°C and low noise characteristics, specified at 4µVp-p over the 0.1Hz to 10Hz frequency band. The component supports a maximum output current of 10mA and is housed in an 8-SOIC surface-mount package.

Feature Summary

• Provides stable 5V reference output with high initial accuracy
• Features low noise performance for sensitive analog applications
• Operates with wide input voltage range up to 30V

Applications

• Precision data acquisition systems
• High-resolution analog-to-digital converters
• Calibration equipment requiring stable voltage references

Procurement Notes

Verify the specific suffix 'CESA+T' against official Analog Devices documentation to confirm the commercial temperature grade and tape-and-reel packaging configuration. Ensure compatibility with RoHS directives as indicated by the '+' suffix. Cross-reference the manufacturer's latest datasheet for any potential obsolescence notices or lifecycle changes prior to final procurement decisions.

Selection Notes

Select this component when a fixed 5V reference with ±1% initial accuracy is required. Consider the 15ppm/°C temperature coefficient for thermal stability needs. Verify that the 10mA output current capability meets load requirements. Compare against other members of the REF01/REF02 family if different voltage outputs or tighter tolerances are necessary for the specific design constraints.

Part Context

The REF02CESA+T belongs to the REF02 series of precision voltage references from Analog Devices. This series is designed for applications demanding high stability and low noise. The part integrates a bandgap reference core with output buffering to drive loads while maintaining regulation across the specified operating temperature and voltage ranges.

Replacement Considerations

Consult the official Analog Devices REF01/REF02 datasheet for pin-compatible alternatives within the same family. Verify functional equivalence for voltage, accuracy, and package type before substituting.
