MAX873BESA+

Overview

The MAX873BESA+ is a precision voltage reference providing a fixed +2.5V output in an 8-pin SOIC package. It features a maximum initial accuracy of ±0.1% and a temperature coefficient of up to 20ppm/°C over the -40°C to +85°C operating range. The device operates with a supply voltage between +4.5V and +18V, drawing a maximum quiescent current of 600µA. It can source up to 10mA and sink up to 2mA, with line regulation at 6ppm/V and load regulation at 20ppm/mA.

Feature Summary

Provides a stable +2.5V reference with low power consumption suitable for battery-operated systems
Includes a dedicated TEMP pin that outputs a voltage proportional to die temperature for compensation applications
Features a TRIM pin allowing output voltage adjustment via an external potentiometer
Offers short-circuit protection limiting output current when connected to ground or input

Applications

12-bit ADCs and DACs
Digital Multimeters
Portable Data-Acquisition Systems
Low-Power Test Equipment

Procurement Notes

Verify the specific suffix 'B' indicates the ±0.1% accuracy grade and 'E' denotes the industrial temperature range. Confirm the '+T' or standard tube packaging matches your assembly requirements. Ensure the supplier provides traceability documentation for lead-free compliance as indicated by the '+' designation.

Selection Notes

Select this component when a fixed 2.5V reference is required with moderate precision and low power constraints. The MAX873BESA+ is appropriate for systems running from a +5V supply where the wide input voltage range allows flexibility. Consider the TEMP pin utility if thermal monitoring is needed within the circuit design.

Part Context

This part belongs to the MAX873/MAX875/MAX876 family of low-power, low-drift precision voltage references. While the MAX875 offers +5V and the MAX876 offers +10V, the MAX873 specifically targets the +2.5V requirement. All variants share similar architectural features including curvature-correction circuits and laser-trimmed thin-film resistors.
