MAX6133BASA41+T

Overview

The MAX6133BASA41+T is a high-precision series voltage reference featuring bandgap technology and laser-trimmed thin-film resistors. It delivers a fixed output of 4.096V with an initial accuracy of ±0.08% and a maximum temperature coefficient of 5ppm/°C across the -40°C to +125°C range. The device operates on a supply voltage from 4.2V to 12.6V, consuming only 40µA of quiescent current. It provides up to 15mA of source current capability and maintains stability with capacitive loads up to 100µF.

Feature Summary

• Ultra-low power consumption with virtually constant supply current independent of input voltage
• High precision achieved through post-package trimming and laser-stable thin-film resistors
• Low dropout voltage design enables efficient operation in battery-powered systems
• Robust transient response with stable performance under varying capacitive loads

Applications

• Precision regulators for analog circuits
• Reference sources for A/D and D/A converters
• High-accuracy industrial and process control instrumentation
• Hand-held instruments requiring low power and high stability

Procurement Notes

Verify the specific suffix '41' confirms the 4.096V output option. Confirm the 'T' suffix indicates tape-and-reel packaging rather than tube. Ensure the B-grade designation matches the required ±0.08% accuracy specification. Check RoHS compliance status as per manufacturer documentation.

Selection Notes

Select this component when a fixed 4.096V reference is required with strict limits on temperature drift and initial accuracy. The B-grade variant offers higher tolerance compared to the A-grade. Consider the SO package size constraints and the need for external bypassing to ensure optimal line regulation and noise performance.

Part Context

This part belongs to the MAX6133 family of low-power, low-dropout voltage references. It utilizes BiCMOS processing and contains 656 transistors. The device is designed to replace shunt references by saving system power and minimizing external components while maintaining excellent long-term stability and low noise characteristics.

Replacement Considerations

Direct substitutes within the same family include MAX6133AASA41+ for tighter accuracy or MAX6133BASA30+ for different voltage options. Verify pin compatibility and thermal characteristics before substitution.
