MAX875BESA+

Overview

The MAX875BESA+ is a precision voltage reference providing a fixed +5.0V output in an 8-pin SOIC package. It features a maximum initial accuracy of ±0.06% 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 maximum quiescent current of 450µA. It can source 10mA and sink 2mA, with line regulation at 4ppm/V and load regulation at 15ppm/mA.

Feature Summary

• Provides a stable +5.0V reference with high initial accuracy and low temperature drift for precise measurement applications.
• Includes a dedicated TEMP pin that outputs a voltage proportional to die temperature for compensation or monitoring.
• Features a TRIM pin allowing adjustment of the output voltage over a ±6% range using external resistive networks.

Applications

• 12-bit ADCs and DACs
• Digital Multimeters
• Portable Data-Acquisition Systems

Procurement Notes

Verify the specific suffix 'B' indicates the ±0.06% accuracy grade and 'E' denotes the industrial temperature range. Confirm the 'SA' package code corresponds to the 8-lead Small Outline package. Ensure the '+' suffix confirms lead-free compliance as per the manufacturer's ordering guide.

Selection Notes

Select this component when a fixed +5.0V reference is required with moderate precision (±0.06%) and standard industrial temperature coverage. It is suitable for systems where low power consumption is critical but ultra-low drift is not mandatory compared to the 'A' grade variants.

Part Context

This part belongs to the MAX873/MAX875/MAX876 family of low-power, low-drift precision voltage references. While sharing the same architecture and pinout, the MAX875 variant specifically provides a +5.0V output, distinguishing it from the +2.5V MAX873 and +10V MAX876 models within the series.
