MAX6133A30+T

Overview

The MAX6133A30+T is a series voltage reference IC manufactured by Analog Devices Inc./Maxim Integrated, featuring a fixed output of 3.000V. It operates within an input voltage range of 3.2V to 12.6V and delivers a maximum source current of 15mA. The device exhibits an initial accuracy of ±0.04% and a maximum temperature coefficient of 3ppm/°C across the -40°C to +125°C operating range. Quiescent supply current is typically 40µA, with a maximum dropout voltage of 200mV at 10mA load.

Feature Summary

• Bandgap technology ensures low-noise performance and high precision
• Laser-trimmed thin-film resistors provide excellent initial accuracy
• Low quiescent current maximizes efficiency in battery-powered systems
• Minimal external component requirements compared to shunt references

Applications

• Precision regulators
• A/D and D/A converters
• Power supplies
• High-accuracy industrial and process control
• Hand-held instruments

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm the 'A' grade designation matches the required 3ppm/°C temperature coefficient specification for your application. Ensure the SOIC-8 package variant aligns with your PCB footprint requirements. Cross-reference the manufacturer's latest datasheet revision to confirm pinout consistency.

Selection Notes

Select this part for applications requiring high stability and low power consumption. The 3V output is suitable for driving ADCs or DACs directly. Consider the 15mA source capability if driving moderate loads. Verify that the input voltage remains above the minimum dropout threshold to maintain regulation. Evaluate thermal management needs based on the specified derating curves.

Part Context

This component belongs to the MAX6133 family of high-precision, low-power voltage references. The family includes variants with different output voltages (2.5V, 4.096V, 5.0V) and packages (SOIC, µMAX). The A-grade devices offer superior temperature coefficients compared to B-grade options. The series-mode architecture distinguishes it from traditional shunt references.

Replacement Considerations

Check for direct replacements within the MAX6133 family such as MAX6133AASA25+T or MAX6133AASA41+T for different voltage outputs. Verify compatibility with other Maxim series references like MAX6033 if package constraints differ.
