MAX876AESA+T

Overview

The MAX876AESA+T is a precision voltage reference providing a fixed +10.0V output in an 8-pin SOIC package. It features a maximum temperature coefficient of 7ppm/°C and initial accuracy of ±0.03%. The device operates with a supply voltage range of +4.5V to +18V, drawing a typical quiescent current of 320µA. It supports sourcing up to 10mA and sinking up to 2mA, with line regulation at 4ppm/V and load regulation at 15ppm/mA. The unit includes a TRIM pin for ±6% voltage adjustment and a TEMP pin for temperature monitoring.

Feature Summary

• Provides a stable +10V reference with low drift and high initial accuracy
• Includes a dedicated pin for temperature-proportional voltage output
• Allows external trimming of the output voltage via a resistive divider
• Features short-circuit protection on the output terminal

Applications

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

Procurement Notes

Verify the specific suffix against official documentation to confirm lead-free status and package variant. Confirm availability through authorized distributors as supply may be restricted. Ensure the ordering code matches the required electrical grade and thermal performance specifications.

Selection Notes

Select this component when a fixed +10V precision reference is required with minimal power consumption. The integrated temperature output simplifies compensation circuits. Verify that the input voltage range accommodates the system supply rails and that the load current requirements fall within the specified source and sink limits.

Part Context

This part belongs to the MAX873/MAX875/MAX876 family of low-power, low-drift precision voltage references. The series offers +2.5V, +5V, and +10V options in identical packages, sharing common features such as laser-trimmed thin-film resistors and curvature-correction circuitry for stability across wide temperature ranges.
