MAX872ESA+

Overview

The MAX872ESA+ is a precision series voltage reference manufactured by Analog Devices Inc. under the Maxim Integrated brand. It provides a fixed output voltage of 2.5V with an initial accuracy of ±0.48%. The device operates within an input voltage range of 2.7V to 20V and draws a supply current of 15µA. It features a temperature coefficient of 40ppm/°C and exhibits low noise characteristics, specifically 60µVp-p in the 0.1Hz to 10Hz band. Designed for surface-mount installation, it is housed in an 8-SOIC package (0.154 inch width) and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Delivers a stable 2.5V fixed output with high initial accuracy of ±0.48%.
• Features low power consumption with a supply current of only 15µA.
• Provides low noise performance suitable for sensitive analog circuits.

Applications

• Precision data acquisition systems
• Analog-to-digital converter (ADC) references
• Digital-to-analog converter (DAC) references

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm RoHS compliance status and specific lot traceability requirements before procurement. Ensure storage conditions align with moisture sensitivity level specifications to maintain device integrity during assembly processes.

Selection Notes

Select this component when a precise 2.5V reference is required with tight initial tolerance and low power operation. Consider the 8-SOIC package dimensions for PCB layout compatibility. Evaluate thermal management needs based on the specified operating temperature range and ambient conditions of the target application environment.

Part Context

This part belongs to the MAX872 series of precision voltage references from Maxim Integrated, now part of Analog Devices Inc. The series is designed for applications requiring stable reference voltages with minimal drift over temperature and time. The MAX872 variant specifically offers a 2.5V output, distinguishing it from other outputs in the family such as 2.5V, 5V, or 10V options available in related part numbers.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify pinout and electrical parameter compatibility if considering alternative voltage references from other manufacturers.
