MAX6138AEXR21+T

Overview

The MAX6138AEXR21+T is a precision, two-terminal shunt mode bandgap voltage reference manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed reverse breakdown output voltage of 2.048V with an initial accuracy of 0.1%. The device operates within a temperature range of -40°C to +85°C and features a maximum temperature coefficient of 25ppm/°C. It supports a wide operating current range from 60μA to 15mA and utilizes a subminiature 3-pin SC70 surface-mount package.

Feature Summary

Ultra-small 3-pin SC70 package for space-critical applications
Laser-trimmed resistors ensure precise initial accuracy
Low dynamic impedance ensures stable reverse breakdown voltage accuracy
Operates without external stabilizing capacitors while remaining stable with capacitive loads

Applications

Portable, battery-powered equipment
Notebook computers
Cell phones
Industrial process control

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm exact electrical tolerances and packaging specifications. Confirm RoHS compliance status through authorized distributors or direct manufacturer channels before procurement. Ensure the component matches the required pin configuration and thermal characteristics for the intended circuit design.

Selection Notes

Select this component when high precision and compact form factor are required in portable electronics. The 0.1% initial accuracy and low temperature drift make it suitable for sensitive analog circuits. Evaluate the power dissipation limits and source resistance requirements to maintain operation within the specified 60μA to 15mA shunt current range.

Part Context

This part belongs to the MAX6138 family of precision shunt voltage references. The series offers multiple fixed reverse breakdown voltages including 1.2205V, 2.5V, 3.0V, 3.3V, 4.096V, and 5.0V. Variants are available with different initial accuracy grades ranging from 0.1% to 0.5%, all housed in the same 3-pin SC70 package.
