MAX6037BAUK41-T

Overview

The MAX6037BAUK41-T is a low-power, fixed-output voltage reference IC from the MAX6037 series. It provides a nominal output voltage of 4.096V with an initial accuracy of ±0.3%. The device operates within a temperature range of -40°C to +125°C and features a maximum temperature coefficient of 50ppm/°C. It draws a typical quiescent current of 5µA and supports a load current up to 5mA. The component is housed in a compact SOT-23-5 package.

Feature Summary

• Low-power operation with microampere-level quiescent current consumption
• High precision with tight initial accuracy and low temperature drift
• Automotive-grade reliability across extended industrial temperature ranges
• Compact footprint utilizing a five-pin surface-mount package

Applications

• Precision analog-to-digital converter (ADC) reference sources
• Digital-to-analog converter (DAC) voltage references
• Battery-powered instrumentation requiring low standby power
• Portable medical devices needing stable voltage regulation

Procurement Notes

Verify the specific suffix (+T) indicates tape-and-reel packaging when ordering. Confirm the exact output voltage variant matches the design requirement, as the MAX6037 series offers multiple fixed options. Ensure the operating environment stays within the specified -40°C to +125°C range for guaranteed performance. Cross-reference the datasheet for thermal dissipation limits in the SOT-23-5 package.

Selection Notes

Select this part when a stable 4.096V reference is required with minimal power draw. Compare against adjustable variants if flexible output voltages are needed. Consider the ±0.3% initial accuracy for high-resolution data acquisition systems. Evaluate the 50ppm/°C temperature coefficient against stricter stability requirements that might necessitate higher-grade references.

Part Context

This component belongs to the Maxim Integrated MAX6037 family of low-power voltage references. The series includes both fixed and adjustable output versions, designed for battery-operated applications. The BAUK41 designation specifically identifies the 4.096V fixed output variant within the automotive-grade product line.

Replacement Considerations

Direct substitutes include other MAX6037 variants with different fixed output voltages if the system allows voltage adjustment. Verify pin compatibility with the SOT-23-5 package before replacing. Check if adjacent parts like the MAX6038 offer improved noise or drift specifications if performance upgrades are necessary.
