MAX6043AAUT50#G16

Overview

The MAX6043AAUT50#G16 is a precision series voltage reference IC manufactured by Analog Devices Inc. under the Maxim Integrated brand. It provides a fixed output voltage of 5V with an initial accuracy of ±0.06%. The device operates within an input voltage range of 6.1V to 40V and supports a maximum shunt current of 10 mA. Key electrical characteristics include a temperature coefficient of 15ppm/°C, low noise performance (9.5µVp-p from 0.1Hz to 10Hz), and a supply current of 650µA. It is housed in a compact SOT-23-6 surface-mount package and functions reliably across an extended industrial temperature range of -40°C to +125°C.

Feature Summary

• Delivers high-precision fixed voltage output with tight initial tolerance
• Features ultra-low noise characteristics for sensitive signal chains
• Operates on a wide input voltage range up to 40V
• Designed for stable performance across extreme temperature environments

Applications

• High-resolution data acquisition systems
• Precision analog-to-digital converter references
• Medical instrumentation requiring stable bias voltages
• Industrial process control sensors

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for End-of-Life notices, as discontinuation may affect long-term availability. Ensure ordering suffixes match specific packaging requirements such as reel quantities. Validate that the received part matches the exact marking and date code specifications required for your production timeline.

Selection Notes

Select this component when a fixed 5V reference with sub-0.1% accuracy is required. Consider the 15ppm/°C temperature coefficient for applications demanding minimal drift over temperature variations. Evaluate the 650µA supply current against power budget constraints. Ensure the input voltage remains above the minimum dropout level while staying within the 40V absolute maximum rating.

Part Context

This part belongs to the MAX6043 family of precision voltage references, designed for high-performance analog circuits. The 'A' grade indicates tighter accuracy specifications compared to standard grades. The '#G16' suffix typically denotes lead-free packaging compliant with environmental directives. This series integrates bandgap reference technology optimized for low noise and high stability in small form factors.

Replacement Considerations

Check for MAX6043 variants with different output voltages or accuracy grades if system requirements change. Verify pinout compatibility before substituting with other series references. Consult official datasheets for thermal and electrical parameter overlaps to ensure functional equivalence without circuit redesign.
