MAX6279ELA12+T

Overview

The MAX6279ELA12+T is a shunt precision voltage reference IC manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed output voltage of 1.225 V with an initial accuracy of ±0.1%. The device features a temperature coefficient of 25 ppm/°C and supports a maximum shunt current of 12 mA. It operates within a temperature range of -40°C to +85°C and is housed in an 8-LCC (3x3 mm) surface-mount package.

Feature Summary

• Provides a stable 1.225 V reference output with high initial accuracy
• Designed for low-noise applications with specified performance metrics
• Operates reliably across extended industrial temperature ranges

Applications

• Precision data acquisition systems
• High-resolution analog-to-digital converter references
• Instrumentation requiring stable voltage benchmarks

Procurement Notes

Verify the specific suffix designation, as standard datasheets often list the MAX6279ELA12+ variant. Confirm that the tape-and-reel packaging aligns with automated assembly requirements. Ensure the component meets RoHS compliance standards for your region. Cross-reference the manufacturer's latest documentation to confirm availability status and lead times before finalizing procurement plans.

Selection Notes

Select this component when a precise 1.225 V reference is required in a compact form factor. The shunt configuration necessitates a series resistor to set operating current. Evaluate thermal management needs given the 12 mA maximum current limit. Ensure the PCB layout minimizes noise coupling to maintain the specified accuracy levels in sensitive analog circuits.

Part Context

This part belongs to the MAX6279 family of shunt voltage references from Maxim Integrated. These devices are engineered for applications demanding high stability and low drift. The family typically includes variants with different output voltages and packages, catering to diverse space and performance constraints in portable and industrial electronics.

Replacement Considerations

Check for direct pin-compatible substitutes within the same product family. Verify that alternative components match the 1.225 V output and 25 ppm/°C temperature coefficient. Ensure the replacement package matches the 8-LCC footprint for seamless integration without board redesign.
