Procurement Notes
Verify that the specific part number matches the required B-grade specifications, including the 0.5% initial accuracy and 75ppm/°C temperature coefficient. Confirm the SOT-23-3 package type and ensure the '+T' suffix indicates tape-and-reel packaging if reel delivery is required. Cross-reference the manufacturer's ordering information to validate the exact electrical tolerances before procurement.
Selection Notes
Select this component when space constraints require a compact SOT-23 footprint alongside low quiescent current requirements. It serves as a direct upgrade for legacy references like the LM285 or LT1004 where higher precision and lower power are needed. Ensure the application bias current remains between 1µA and 2mA to maintain specified performance levels across the full industrial temperature range.
Part Context
This device belongs to the MAX6006–MAX6009 family of ultra-low-power shunt references manufactured by Analog Devices / Maxim Integrated. The family offers various fixed output voltages including 1.25V, 2.048V, 2.5V, and 3.0V. These devices utilize BiCMOS processes and laser-trimmed thin-film resistors to achieve their specified accuracies and stability characteristics.
Replacement Considerations
The datasheet identifies the ICL8069, LM385, LT1004, and LM4040 as legacy references that can be upgraded to this series. Specifically, the MAX6008 acts as a plug-in upgrade for the LT1004 and LM285 in 8-pin SO packages, though the BEUR variant utilizes a different SOT-23 form factor requiring layout adjustments.
FAQ
What is the minimum operating current for the MAX6008BEUR+T?
The minimum operating current is guaranteed to be less than 1µA.
How does the B grade differ from the A grade in terms of accuracy?
The B grade has an initial accuracy of 0.5% and a temperature coefficient of 75ppm/°C, whereas the A grade offers 0.2% accuracy and 30ppm/°C.
Is an external capacitor required for stability?
Yes, the OUT pin must be bypassed to GND with a 0.01µF or larger capacitor.
