Procurement Notes

Verify the exact suffix configuration against official datasheets, as variations such as +T or -T may indicate specific packaging or tape-and-reel options. Confirm availability status, as this component may be subject to limited supply or end-of-life restrictions. Ensure compatibility with existing PCB footprints and verify that the selected variant meets all required electrical specifications for your design environment.

Selection Notes

Select this component when a highly accurate 2.048 V reference is required with minimal drift over temperature. The 0.2% initial accuracy makes it suitable for high-resolution data conversion applications. Consider the SOT-23-5 package size for board space limitations. Evaluate the 5 mA maximum shunt current to ensure it meets the load requirements of your circuit without exceeding thermal limits.

Part Context

This part belongs to the MAX6037 family of low-power, micropower voltage references. The series offers various fixed and adjustable output options in small packages. The CAUK21 designation specifically indicates the 2.048 V output variant with 0.2% accuracy.
