MAX6120ESA+T

Overview

The MAX6120ESA+T is a precision, low-power, three-terminal voltage reference providing a fixed 1.2V output. It operates from a supply voltage range of 2.4V to 11V with a maximum quiescent supply current of 70µA, which remains independent of the input voltage over temperature. The device features an initial accuracy of ±1% and a typical output voltage temperature coefficient of 30ppm/°C. It is housed in an 8-pin SOIC package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Micropower operation with supply current independent of input voltage
• Precision 1.2V output with ±1% initial accuracy
• Low temperature coefficient for stable performance across temperature ranges

Applications

• Battery-powered systems
• Portable and hand-held equipment
• Data-acquisition systems
• Instrumentation and process control

Procurement Notes

Verify the specific package type against project requirements, as the MAX6120 series includes both SOT23-3 and SOIC-8 variants. Confirm that the selected component matches the required pinout and thermal characteristics. Ensure compatibility with the intended operating temperature range and verify that the supply voltage constraints align with system power rails before finalizing procurement.

Selection Notes

Select this component when a fixed 1.2V reference is required with minimal power consumption. It serves as a low-power alternative to two-terminal shunt references by eliminating the need for external series resistors. Consider its independence of supply current from input voltage for efficient battery management in portable applications requiring stable voltage regulation.

Part Context

This part belongs to the MAX6120 family of micropower voltage references manufactured by Analog Devices / Maxim Integrated. While the datasheet highlights the SOT23 package for its ultra-low power profile, the ESA suffix indicates the SOIC-8 variant. This family provides precision voltage referencing solutions designed for cost-sensitive and space-constrained electronic designs.

Replacement Considerations

Consult the MAX6520 data sheet if a guaranteed output voltage temperature coefficient of less than 50ppm/°C is required. Verify pin compatibility and package dimensions when substituting other voltage references in existing layouts.
