MAX6033BAUT25

Overview

The MAX6033BAUT25 is a series voltage reference IC manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed output voltage of 2.5V with an initial accuracy tolerance of ±0.2%. The device operates within an input voltage range of 2.7V to 12.6V and supports a maximum load current of 15 mA. It features a temperature coefficient of 15 ppm/°C and consumes a supply current of 85 µA. The component is housed in a SOT-23-6 surface-mount package and functions reliably across a temperature range of -40°C to +125°C.

Feature Summary

• Delivers high precision with ±0.2% initial accuracy for stable reference applications
• Operates efficiently with low power consumption of 85 µA supply current
• Provides robust thermal stability with a temperature coefficient of 15 ppm/°C

Applications

• Precision analog-to-digital converter (ADC) reference sources
• Data acquisition systems requiring stable voltage baselines
• Portable instrumentation powered by single-supply batteries

Procurement Notes

Verify the specific suffix and manufacturer designation when sourcing, as legacy Maxim Integrated parts may carry different marking codes or obsolescence notices. Confirm RoHS compliance status and check for active production or last-time-buy notifications through authorized distributors. Ensure the SOT-23-6 footprint matches your PCB design constraints before finalizing procurement orders.

Selection Notes

Select this component when a compact SOT-23-6 package is required alongside moderate precision levels. The 2.5V output suits systems needing standard reference levels without external trimming. Consider the 15 ppm/°C drift if operating in environments with significant thermal fluctuations compared to higher-grade alternatives.

Part Context

This part belongs to the MAX6033 family of ultra-high-precision voltage references designed for space-constrained applications. The BAUT25 variant specifically denotes the 2.5V output option with 0.2% accuracy. It complements other series references like the MAX6035 and MAX6043, offering a balance between performance and package size for general-purpose precision circuits.

Replacement Considerations

MAX6033AAUT25#TG16 offers tighter ±0.04% accuracy. MAX6033CAUT25#TG16 provides ±0.1% accuracy. Both share the same SOT-23-6 package and pinout.
