Overview
The MAX6009AEUR+T is a precision, two-terminal shunt voltage reference from the MAX6006–MAX6009 family. It provides a fixed +3.0V 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 ultra-low power consumption with a minimum operating current guaranteed below 1µA. Packaged in a compact 3-pin SOT-23 format, it serves as a high-precision alternative to legacy references.
Feature Summary
- Ultra-low operating current with a guaranteed minimum threshold below 1µA
- High initial voltage accuracy of 0.2% achieved through laser trimming
- Low temperature coefficient of 30ppm/°C for stable performance across extended temperatures
- Compact 3-pin SOT-23 package designed for space-constrained applications
Applications
- Battery-powered equipment
- Portable meters
- Precision regulators
- A/D and D/A converters
Procurement Notes
Verify the specific suffix 'EUR' corresponds to the tape-and-reel packaging configuration when sourcing. Confirm that the component meets lead-free and RoHS compliance requirements as indicated by the '+' designation. Ensure the ordering part number matches the required A-grade specifications for the stated accuracy and temperature coefficient parameters.
Selection Notes
Select this component for designs requiring a fixed 3.0V reference with minimal quiescent current draw. It is suitable for replacing older generation references like the LM4040 where lower power and smaller footprint are priorities. Verify that the application bias current remains within the 1µA to 2mA operational window to maintain specified accuracy levels.
Part Context
This device belongs to the MAX6006–MAX6009 series of ultra-low-power shunt references manufactured by Analog Devices / Maxim Integrated. The series offers multiple fixed output voltages including 1.25V, 2.048V, 2.5V, and 3.0V. These devices utilize BiCMOS process technology and feature on-chip thin-film resistors for precise factory trimming.
Replacement Considerations
The datasheet identifies the ICL8069, LM385, LT1004, and LM4040 as legacy references that can be upgraded using this series. Specific pin-compatible replacements depend on the required output voltage; for example, the MAX6008AEUR+T serves as a direct upgrade for the +2.5V variants of these legacy parts.
