MAX6133A41+T

Overview

The MAX6133A41+T is a high-precision, low-power series voltage reference featuring a fixed 4.096V output in an 8-pin SO package. It delivers ±0.04% initial accuracy and a maximum temperature coefficient of 3ppm/°C across the -40°C to +125°C range. The device operates with a supply voltage from 4.2V to 12.6V, consuming only 40µA quiescent current. It supports source currents up to 15mA with a dropout voltage of 0.2V at 10mA load.

Feature Summary

• Laser-trimmed thin-film resistors ensure high stability and precision
• Bandgap technology provides low-noise performance
• Low dropout voltage enables efficient operation near minimum input levels
• Minimal external component requirements compared to shunt references

Applications

• Precision regulators
• A/D and D/A converters
• High-accuracy industrial and process control systems

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging for automated assembly. Confirm the 'A' grade designation matches the required ±0.04% accuracy specification. Ensure the 8-pin SO package footprint aligns with the target PCB layout. Validate that the 4.096V output voltage meets the system design requirements before procurement.

Selection Notes

Select this part when a fixed 4.096V reference is needed with tight tolerance and low drift. The SO package offers a balance between size and thermal dissipation. Consider the 40µA supply current for battery-powered applications. Verify that the input voltage range accommodates the system's supply variations while maintaining regulation.

Part Context

This component belongs to the MAX6133 family of low-dropout voltage references. The family includes variants with different output voltages and packages. The 'A' grade denotes tighter accuracy specifications than the 'B' grade. The MAX6133 is designed for portable and communication applications requiring small form factors.

Replacement Considerations

Check for direct substitutes within the MAX6133 family with matching voltage and package. Verify pin compatibility if replacing with other Maxim Integrated voltage references. Ensure thermal characteristics and operating temperature ranges are equivalent for the new component.
