MAX872CPA

Overview

The MAX872CPA is a precision series voltage reference manufactured by Analog Devices Inc. under the Maxim Integrated brand, housed in an 8-pin PDIP package. It provides a fixed output voltage of 2.5V with an initial accuracy of 0.38%. The device operates within an extended temperature range from -40°C to +85°C and supports an input voltage range of 2.7V to 20V. Key electrical characteristics include a temperature coefficient of 40ppm/°C and a maximum shunt current of 10mA.

Feature Summary

• Provides stable precision voltage reference performance suitable for high-accuracy applications
• Features low drift characteristics over temperature variations
• Designed for surface mount or through-hole integration via standard packaging

Applications

• Precision analog-to-digital converter (ADC) references
• Digital-to-analog converter (DAC) voltage sources
• High-resolution measurement instrumentation systems
• Calibration equipment requiring stable reference voltages

Procurement Notes

Verify component authenticity due to limited availability status. Confirm package integrity and pin configuration compatibility before integration. Check for RoHS compliance documentation if required by specific manufacturing standards. Ensure supply chain sources are authorized distributors to avoid counterfeit risks associated with discontinued or restricted lifecycle parts.

Selection Notes

Select this component when a fixed 2.5V reference with 0.38% initial accuracy is required. Consider the 40ppm/°C temperature coefficient for thermal stability needs. Evaluate the 2.7V minimum input voltage against system power rails. Compare against the MAX873 family for lower drift options if higher precision is necessary.

Part Context

Part of the MAX87x series of precision voltage references designed for demanding analog signal processing tasks. Manufactured by Analog Devices Inc./Maxim Integrated, it serves as a foundational component in power management integrated circuits (PMIC). The part is categorized under Series Precision References within the broader PMIC product line.

Replacement Considerations

Consider the MAX873BCSA or MAX873BESA+ for applications requiring lower temperature coefficients and tighter accuracy specifications. Verify pinout compatibility between PDIP-8 and SOIC packages during substitution planning.
