MAX876BESA+T

Overview

The MAX876BESA+T is a precision voltage reference providing a fixed +10V output in an 8-pin SOIC package. It features a maximum initial accuracy of ±0.05% and a temperature coefficient of 20 ppm/°C over the -40°C to +85°C operating range. The device operates with a supply voltage up to +18V, drawing a typical quiescent current of 340µA. It supports sourcing 10mA and sinking 2mA, with low noise characteristics suitable for high-resolution data acquisition systems.

Feature Summary

• Provides a stable +10V precision reference with laser-trimmed thin-film resistors
• Includes a dedicated TEMP pin generating an output voltage proportional to die temperature
• Features a TRIM pin allowing output voltage adjustment via external potentiometer
• Offers short-circuit protection limiting output current when connected to ground

Applications

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

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the presence of the lead-free (+) designation and ensure the suffix matches the specific tape-and-reel packaging requirements for automated assembly processes.

Selection Notes

Select this component when a fixed +10V reference is required with tight initial accuracy specifications. Consider the integrated temperature output feature if system-level thermal compensation is necessary without additional sensors. Evaluate the low quiescent current consumption against battery-operated design constraints.

Part Context

This part belongs to the MAX873/MAX875/MAX876 family of low-power, low-drift precision voltage references. While sharing identical pinouts and general architecture, the MAX876 is distinguished by its fixed +10V output level compared to the +2.5V and +5V variants within the same series.
