MAX6133A25+

Overview

The MAX6133A25+ is a high-precision, low-power series voltage reference manufactured by Analog Devices Inc. (Maxim Integrated). It delivers a fixed output of 2.5V with an initial accuracy of ±0.06% and a maximum temperature coefficient of 5ppm/°C in the µMAX package. The device operates within a supply voltage range of 2.7V to 12.6V, consuming a typical quiescent current of 40µA. It features a maximum dropout voltage of 200mV and supports source currents up to 15mA. The component is housed in an 8-pin µMAX surface-mount package and functions reliably across an extended temperature range from -40°C to +125°C.

• Ultra-low temperature coefficient ensures minimal drift over wide operating ranges
• Low quiescent current consumption maximizes efficiency in battery-powered systems
• High initial accuracy maintained through laser-trimmed thin-film resistors
• Compact packaging design suitable for space-constrained portable applications

Applications

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

Procurement Notes

Verify that the specific part number matches the required package type and output voltage grade. Confirm RoHS compliance status as indicated on official documentation. Ensure the supplier provides valid traceability for the manufacturing lot. Check for any regional distribution restrictions or obsolescence notices prior to finalizing procurement orders.

Selection Notes

Select this component when system requirements demand high precision combined with low power consumption. The 2.5V output is ideal for driving analog-to-digital converters requiring stable references. Consider the thermal performance and package size constraints when choosing between SO and µMAX variants. Verify input voltage headroom against the specified dropout characteristics for optimal regulation.

Part Context

This device belongs to the MAX6133 family of bandgap voltage references designed for high-performance applications. It utilizes post-package trimming to achieve superior accuracy compared to standard commercial-grade references. The series-mode architecture distinguishes it from shunt references by offering better load regulation and lower power dissipation under varying load conditions.

Replacement Considerations

Direct replacements include other MAX6133 variants with different output voltages such as MAX6133A30+, MAX6133A41+, or MAX6133A50+. Cross-family alternatives may require verification of pin compatibility and electrical parameter alignment.
