MAX6133BASA25+T

Overview

The MAX6133BASA25+T is a high-precision, low-power, low-dropout series voltage reference manufactured by Analog Devices/Maxim Integrated. It provides a fixed 2.500V output with a maximum initial accuracy of ±0.08% and a temperature coefficient of 5ppm/°C over the -40°C to +125°C range. The device operates from an input voltage range of 3.2V to 12.6V, consuming typically 40µA of quiescent current. It features a maximum dropout voltage of 0.4V at 10mA load and supports source currents up to 15mA. Packaged in an 8-pin SOIC-Narrow (SO) format.

Feature Summary

• Bandgap technology ensures low-noise performance and excellent accuracy through laser-trimmed thin-film resistors and post-package trimming.
• Series-mode architecture minimizes external component requirements and system power consumption compared to shunt references.
• Capable of sourcing up to 15mA while maintaining stability with capacitive loads up to 100µF.

Applications

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

Procurement Notes

Verify the specific suffix '25' confirms the 2.500V output option and 'T' indicates tape-and-reel packaging. Confirm the 'BASA' designation corresponds to the B-grade accuracy and SO package variant. Ensure compatibility with the required operating temperature range of -40°C to +125°C for your application environment.

Selection Notes

Select this component when a fixed 2.5V precision reference is required with tight initial accuracy and low temperature drift. The B-grade specification offers ±0.08% accuracy suitable for general precision applications. Consider the 5ppm/°C temperature coefficient if wider temperature stability than A-grade is not strictly necessary, balancing cost and performance needs.

Part Context

This part belongs to the MAX6133 family of low-power voltage references. The 'BASA' prefix denotes the B-grade accuracy level and the 8-pin Small Outline (SO) package. The '25' suffix specifies the 2.500V output voltage option. The '+T' suffix indicates the reel packaging format for automated assembly.
