MAX6043BAUT50+T

Overview

The MAX6043BAUT50+T is a precision series voltage reference IC manufactured by Analog Devices Inc. under the Maxim Integrated brand. It provides a fixed output voltage of 5 V with an initial accuracy of ±0.1%. The device operates within an input voltage range of 4.5 V to 40 V and draws a supply current of 650 µA. It features low noise characteristics, specified as 9.5 µVp-p from 0.1 Hz to 10 Hz and 15 µVrms from 10 Hz to 10 kHz. The temperature coefficient is 25 ppm/°C, and it supports a maximum output current of 10 mA. The component functions across an extended temperature range from -40°C to +125°C and is housed in a compact SOT-23-6 surface-mount package.

Feature Summary

• Delivers high-precision voltage regulation with ±0.1% initial accuracy for critical measurement applications.
• Maintains stable performance over a wide input voltage span up to 40 V while consuming minimal quiescent current.
• Provides ultra-low noise output suitable for sensitive analog signal processing environments.

Applications

• High-resolution data acquisition systems requiring precise analog-to-digital conversion references
• Industrial sensor conditioning circuits demanding long-term stability
• Medical instrumentation utilizing accurate voltage benchmarks

Procurement Notes

Verify the specific suffix and tape-and-reel packaging details against official distributor catalogs before ordering. Confirm RoHS compliance status and lead times directly with authorized suppliers. Ensure the procurement channel is authorized to guarantee component authenticity and traceability. Check for any recent product change notices or lifecycle status updates that may affect availability.

Selection Notes

Select this component when a fixed 5 V reference with tight tolerance is required in a small footprint. Consider the 650 µA supply current and 10 mA load capability against system power budgets. Evaluate the 25 ppm/°C temperature coefficient against environmental operating conditions. Compare noise specifications with other series references if ultra-low jitter is critical for the application.
