MAX6069CBAWS+T

Overview

The MAX6069CBAWS+T is a precision shunt voltage reference manufactured by Analog Devices Inc./Maxim Integrated. It provides a nominal output voltage of 2.5V with an initial accuracy of 0.5% and a maximum temperature coefficient of 50ppm/°C over the -40°C to +85°C range. The device operates within an extended temperature range of -40°C to +125°C, featuring a minimum operating current below 1μA and a wide operating current range from 1μA to 2mA. Packaged in a compact 4-bump wafer-level package (WLP) measuring 0.88mm x 1.16mm, it is designed for space-constrained applications.

Feature Summary

• Ultra-low power consumption with guaranteed minimum operating current less than 1μA
• Compact 4-bump wafer-level package (WLP) suitable for space-critical designs
• Factory-trimmed output voltages ensuring high initial accuracy
• Low temperature coefficient for stable performance across varying thermal conditions

Applications

• Portable Sensors
• Portable Meters
• Precision Regulators
• A/D and D/A Converters
• 4mA–20mA Loop-Powered Sensors

Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging when sourcing. Confirm that the 'B' grade designation corresponds to the required 0.5% initial accuracy and 50ppm/°C temperature coefficient specifications. Ensure compatibility with the WLP-4 footprint and land pattern requirements during PCB layout. Check for RoHS compliance status indicated by the '+' suffix.

Selection Notes

Select this component when a small form factor is critical alongside low quiescent current requirements. The B grade offers a balance between cost and precision, suitable for applications tolerating 0.5% initial accuracy. Consider the 2.5V output level relative to system supply rails and ADC/DAC input ranges. Evaluate the need for external bypass capacitors to ensure stability and transient response performance.

Part Context

This part belongs to the MAX6069 family of ultra-tiny shunt voltage references. It serves as a lower-power, higher-precision alternative to legacy devices like the ICL8069, LM385, LT1004, and LM4040. The family includes variants with different output voltages (+1.25V, +2.048V, +2.5V, +3.0V) and grades (A and B). It is functionally equivalent to the MAX6006/MAX6007/MAX6008/MAX6009 series but in a significantly smaller package.

Replacement Considerations

Functionally equivalent parts include the MAX6006, MAX6007, MAX6008, and MAX6009. Legacy replacements may include the ICL8069, LM385, LT1004, and LM4040, though these typically require larger packages.
