MAX6033CAUT41+T

Overview

The MAX6033CAUT41+T is a high-precision series voltage reference with a nominal output of 4.096V, housed in a 6-pin SOT-23 package. It features an initial accuracy of ±0.1% and a maximum temperature coefficient of 40ppm/°C across the -40°C to +125°C automotive range. The device operates on a supply voltage between 4.3V and 12.6V, drawing a typical quiescent current of 40µA while sourcing up to 15mA. It includes separate force (OUTF) and sense (OUTS) outputs for precision regulation.

Feature Summary

• Utilizes bandgap technology with laser-trimmed thin-film resistors to ensure excellent initial accuracy and low noise performance.
• Features separate force and sense outputs to enable precise remote sensing and minimize trace resistance errors.
• Maintains stability with capacitive loads up to 100µF, simplifying circuit design for transient response applications.

Applications

• High-resolution analog-to-digital and digital-to-analog converters
• Precision regulators and power supplies
• Hard-disk drive control circuits
• Industrial and process control systems

Procurement Notes

Verify the specific suffix '+T' indicates tape and reel packaging when ordering. Confirm RoHS compliance status as the '+' symbol denotes exemption under lead requirements. Ensure input voltage remains within the specified 4.3V to 12.6V range to maintain guaranteed line regulation and thermal performance.

Selection Notes

Select this component when a stable 4.096V reference is required in a miniature SOT-23 footprint. The CA grade offers a balance of 0.1% accuracy and 40ppm/°C drift suitable for general industrial use. Consider the A or B grades if tighter temperature coefficients or higher initial accuracies are necessary for the application.
