MAX6126A50

Overview

The MAX6126A50 is a series precision voltage reference IC manufactured by Analog Devices Inc. (Maxim Integrated). It provides a fixed output voltage of 5 V with an initial accuracy of ±0.06%. The device operates within an input voltage range of 5.2 V to 12.6 V and supports a maximum load current of 10 mA. Key electrical characteristics include a temperature coefficient of 5 ppm/°C and a supply current of 725 µA. It functions reliably across an extended temperature range from -40°C to +125°C.

Feature Summary

• Ultra-low noise performance for high-precision signal chain applications
• High initial accuracy ensuring stable reference output
• Wide operating temperature range suitable for industrial environments

Applications

• Battery measurement systems
• Cell-stack monitoring
• Analog front-end (AFE) circuits

Procurement Notes

Verify the specific package variant, as the MAX6126A50 designation may correspond to different physical packages such as uMAX-8 or SOIC depending on the suffix. Confirm RoHS compliance status and ensure the selected part number matches the required footprint for your PCB layout. Check current availability as distribution may be restricted in certain regions.

Selection Notes

Select this component when a 5 V reference with ±0.06% accuracy is required. Ensure the input voltage stays between 5.2 V and 12.6 V. Consider the 725 µA quiescent current for power budgeting. Verify that the thermal coefficient of 5 ppm/°C meets the system's drift requirements over the -40°C to +125°C range.

Part Context

The MAX6126A50 belongs to the MAX6126 family of ultra-high-precision, ultra-low-noise voltage references. This series is designed for demanding analog applications requiring stable and accurate voltage sources. The A50 suffix specifically denotes the 5 V output version with ±0.06% initial accuracy.
