MAX6033BAUT30+T

Overview

The MAX6033BAUT30+T is a high-precision series voltage reference featuring a 3.000V output, ±0.2% initial accuracy, and a maximum temperature coefficient of 15ppm/°C. It operates within a supply voltage range of 3.2V to 12.6V, drawing a typical quiescent current of 40µA while sourcing up to 15mA. The device utilizes bandgap technology with laser-trimmed thin-film resistors for stability. It is housed in a miniature 6-pin SOT23 package and supports operation across an extended temperature range from -40°C to +125°C.

Feature Summary

• Ultra-low temperature drift ensures stable performance over time and varying temperatures
• Low dropout voltage allows efficient operation with minimal power dissipation
• Capacitive load stability up to 100µF simplifies circuit design
• Low noise characteristics enhance signal integrity in precision applications

Applications

• Precision regulators
• High-resolution A/D and D/A converters
• Industrial process control systems
• Hard-disk drives
• Hand-held instruments

Procurement Notes

Verify the specific suffix '+T' indicates tape and reel packaging when ordering. Confirm RoHS compliance status as the '+' prefix denotes devices that may include lead exempt under regulations. Ensure the input voltage source can provide sufficient current during turn-on transients to guarantee reliable startup behavior.

Selection Notes

Select this component when system requirements demand high accuracy with moderate temperature stability. The ±0.2% initial accuracy suits applications where tighter tolerances are unnecessary. Verify that the 3.2V minimum input voltage aligns with the available supply rails. Consider the 15mA output capability against expected load currents to ensure adequate drive strength.

Part Context

This part belongs to the MAX6033 family of ultra-high-precision series voltage references manufactured by Analog Devices / Maxim Integrated. The family offers various output voltages and accuracy grades (A, B, C) within the same compact SOT23-6 footprint. The 'B' grade provides a balance between cost and performance, suitable for general-purpose precision instrumentation.

Replacement Considerations

Direct replacements within the same package and pinout include MAX6033CAUT30+T for higher accuracy or MAX6033AAUT30-T for lower temperature drift. Cross-family alternatives like the MAX6035 require verification of pin compatibility and electrical parameter alignment.
