MAX875AESA+

Overview

The MAX875AESA+ is a precision voltage reference providing a fixed +5.0V output in an 8-pin SOIC package. It features a maximum temperature coefficient of 7ppm/°C and initial accuracy of ±0.04%. The device operates with a supply voltage range of +4.5V to +18V, drawing a maximum quiescent current of 450µA. It sources 10mA and sinks 2mA, with line regulation at 4ppm/V and load regulation at 15ppm/mA. Noise is typically 9µVp-p (0.1Hz to 10Hz) and 14.5µVrms (10Hz to 1kHz). A TEMP pin provides a voltage proportional to die temperature.

Feature Summary

• Laser-trimmed thin-film resistors and curvature-correction circuit ensure high stability
• Integrated temperature-proportional output for compensation applications
• Low power consumption suitable for battery-operated systems
• Short-circuit protected output with internal current limiting

Applications

• 12-bit data-acquisition systems
• Digital multimeters
• Portable data-acquisition systems
• Low-power test equipment

Procurement Notes

Verify the component matches the specific +5V output variant within the MAX875 family. Confirm the package code corresponds to the 8-SOIC form factor. Ensure the ordering suffix indicates lead-free compliance if required by assembly specifications. Cross-reference the manufacturer part number against official distributor catalogs to confirm authenticity and revision status before procurement.

Selection Notes

Select this component when a stable +5V reference is required with low drift over wide temperature ranges. Consider the TRIM pin capability if voltage adjustment within a ±6% range is necessary using external potentiometers. Evaluate the quiescent current against system power budgets. Verify that the input voltage range accommodates the specific supply rails available in the target application design.

Part Context

This device belongs to the MAX873/MAX875/MAX876 series of low-power, low-drift precision voltage references manufactured by Analog Devices / Maxim Integrated. The series offers preset outputs of +2.5V, +5V, and +10V respectively. These parts are designed for applications requiring excellent accuracy and very low power consumption under varying electrical and environmental conditions.
