MAX873BESA+T

Overview

The MAX873BESA+T 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 20ppm/°C over the -40°C to +85°C operating range. The device draws a maximum quiescent current of 600µA and supports a supply voltage range from +4.5V to +18V. 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 high initial accuracy and low temperature drift for precision applications.
Includes a dedicated TEMP pin that outputs a voltage proportional to die temperature for compensation circuits.
Features a TRIM pin allowing output voltage adjustment over a ±6% range using external resistive networks.
Offers short-circuit protection limiting output current to 60mA when grounded.

Applications

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

Procurement Notes

Verify the specific suffix 'B' confirms the ±0.1% accuracy grade and 20ppm/°C drift specification. Confirm the '+T' designation indicates tape-and-reel packaging rather than tube. Ensure the component matches the lead-free RoHS standard required for your assembly process. Cross-reference the manufacturer's latest datasheet revision to confirm pinout consistency.

Selection Notes

Select this part when a fixed +2.5V reference is required with moderate precision (±0.1%) and low power consumption. It is suitable for systems powered by +5V supplies due to its guaranteed operation starting at +4.5V input. Consider the TEMP pin if on-die temperature monitoring is needed without additional sensors.

Part Context

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