MAX876AESA+

Overview

The MAX876AESA+ is a precision voltage reference providing a nominal +10.0V output in an 8-pin SO 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 includes a TRIM pin for voltage adjustment and a TEMP pin for temperature monitoring.

Feature Summary

• Provides stable +10V reference with low drift and high accuracy
• Includes dedicated pins for output trimming and temperature sensing
• Features short-circuit protection and wide supply voltage tolerance

Applications

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

Procurement Notes

Verify the specific suffix 'A' indicates the tighter accuracy grade compared to 'B'. Confirm the 'E' suffix denotes the extended industrial temperature range. Ensure the '+' suffix confirms lead-free compliance. Check for RoHS status on official documentation before procurement.

Selection Notes

Select this component when a precise +10V reference is required with minimal temperature drift. Consider the available trim capability if exact voltage calibration is needed. Evaluate the quiescent current against power constraints. Verify that the input voltage range supports the system's supply rails.

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. All variants share similar architectures including curvature-correction circuits and laser-trimmed resistors for stability.

FAQ

How is the output voltage adjusted?

The output voltage can be trimmed using the TRIM pin by connecting a potentiometer between OUT, TRIM, and GND.

What is the function of the TEMP pin?

The TEMP pin provides an output voltage proportional to the die temperature, useful for compensation or monitoring.
