MAX620EPN

Overview

The MAX620EPN+ is a precision voltage reference integrated circuit manufactured by Analog Devices under the Maxim Integrated brand. It provides a stable output voltage of 5V with an initial accuracy of 0.02% and a temperature coefficient of 3 ppm/°C. The device operates within an input voltage range up to 36V and supports a maximum shunt current of 15mA. It functions reliably across a temperature range from -40°C to +85°C, drawing a maximum supply current of 3.3mA. Packaged in a PDIP-8 through-hole format, it belongs to the Series Precision References category.

Feature Summary

• Delivers high-precision 5V output with 0.02% initial accuracy
• Features low temperature drift of 3 ppm/°C for stability
• Supports wide input voltage range up to 36V
• Includes shutdown capability for power management

Applications

• Precision analog-to-digital converter (ADC) references
• Data acquisition systems requiring stable voltage sources
• Industrial instrumentation calibration circuits
• High-resolution measurement equipment

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific ordering suffixes such as EPN for package type. Check for discontinuation notices or lifecycle status updates prior to procurement. Ensure storage conditions align with manufacturer specifications to maintain performance integrity over time.

Selection Notes

Select this component when a fixed 5V precision reference is required with minimal temperature drift. Consider the PDIP-8 package for through-hole assembly needs. Evaluate the 3.3mA supply current against system power budgets. Compare against lower precision alternatives if cost reduction is prioritized over accuracy.

Part Context

Part of the MAX620A series of micropower precision voltage references. Designed for applications demanding high accuracy and long-term stability. Manufactured by Analog Devices Inc., formerly Maxim Integrated. Available in various package options including DIP and SOIC formats depending on suffix.

Replacement Considerations

MAX620ESA+ offers equivalent electrical characteristics in a surface-mount SOIC-8 package. MAX620BEPI+ provides similar performance in a plastic DIP package. Verify pin compatibility and thermal requirements when substituting.
