MAX6008AEUR+T

Overview

The MAX6008AEUR+T is a precision, two-terminal shunt voltage reference from the MAX6006–MAX6009 family. It provides a fixed +2.5V output with an initial accuracy of 0.2% and a maximum temperature coefficient of 30ppm/°C over the -40°C to +85°C range. The device operates within a wide current range of 1µA to 2mA, featuring a minimum operating current guaranteed below 1µA. Packaged in a compact 3-pin SOT23 form factor, it utilizes laser-trimmed thin-film resistors for high stability.

Feature Summary

• Ultra-low power consumption with guaranteed operating current below 1µA
• High precision performance including 0.2% initial accuracy and low temperature drift
• Compact footprint utilizing a space-saving 3-pin SOT23 package

Applications

• Battery-powered equipment
• Portable meters
• Precision regulators
• A/D and D/A converters

Procurement Notes

Verify that the specific part number matches the required A-grade specifications, particularly the 30ppm/°C temperature coefficient and 0.2% accuracy. Confirm the package type is the 3-pin SOT23 variant rather than the 8-pin SO version. Ensure the ordering suffix indicates tape-and-reel packaging if automated assembly is intended. Cross-reference the top-mark code to validate authenticity against official documentation.

Selection Notes

Select this component when system design requires minimal quiescent current alongside strict voltage stability. It serves as a direct upgrade for legacy references like the LM385 or LT1004 where size constraints are critical. Consider the 1µA to 2mA operating window to ensure proper biasing. Evaluate thermal hysteresis requirements, as the device exhibits typical values around 200ppm after temperature cycling.

Part Context

This device belongs to the MAX6006 through MAX6009 series of ultra-low-power shunt references. While other members offer different fixed voltages such as +1.25V or +3.0V, the MAX6008 specifically targets applications requiring a +2.5V reference. The series shares common architectural features, including BiCMOS processing and laser trimming capabilities, ensuring consistent performance characteristics across the product line.

Replacement Considerations

The datasheet identifies the ICL8069, LM385, LT1004, and LM4040 as legacy references suitable for higher-power replacement scenarios.
