MAX6120ESA

Overview

The MAX6120ESA is a precision, micropower voltage reference IC manufactured by Analog Devices under the Maxim Integrated brand. It provides a fixed 1.2V output with an initial accuracy of ±1% and a temperature coefficient of 100ppm/°C. Designed for surface-mount applications, it operates within a supply voltage range of 2.4V to 11V and draws a maximum supply current of 70µA. The device functions reliably across an industrial temperature range from -40°C to +85°C and is housed in an 8-SOIC package.

Feature Summary

• Delivers a stable 1.2V fixed output voltage suitable for precision analog circuits
• Features low power consumption with a maximum supply current of 70µA
• Ensures high stability over temperature variations with a 100ppm/°C coefficient

Applications

• Portable battery-powered instrumentation systems
• Handheld meters requiring precise voltage standards
• Data acquisition systems needing accurate reference sources

Procurement Notes

Verify the specific suffix against official documentation to confirm package type and tape-and-reel availability. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer before procurement. Ensure the ordering part number matches the required tolerance and packaging specifications.

Selection Notes

Select this component when a low-cost, fixed 1.2V reference is required for space-constrained designs. It is appropriate for applications prioritizing moderate accuracy and low quiescent current over ultra-low noise performance. Consider alternative series references if tighter initial accuracy or lower temperature coefficients are necessary for the specific design requirements.

Part Context

This component belongs to the MAX6120 family of micropower voltage references. It serves as a cost-effective solution for general-purpose precision applications where a fixed 1.2V standard is needed. The device complements higher-precision series like the MAX6126 by offering a balance of performance and economy in an 8-pin SOIC footprint.

Replacement Considerations

Check for direct pin-compatible alternatives such as the MAX6120ESA+T for tape-and-reel packaging. Verify that substitute parts maintain the same 1.2V output, ±1% accuracy, and 70µA supply current specifications to ensure circuit compatibility.
