Overview
The MAX6120ESA+ is a precision, micropower, three-terminal voltage reference providing a fixed 1.2V output in an 8-pin SOIC package. It features ±1% initial accuracy and a typical temperature coefficient of 30ppm/°C. The device 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 the operating temperature range of -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 suffix 'ESA+' corresponds to the 8-pin SOIC package variant rather than the SOT23-3 package. Confirm that the required initial accuracy and temperature coefficient specifications align with the datasheet guarantees for this package type before finalizing procurement orders.
Selection Notes
Select this component when a low-cost, precision 1.2V reference is needed in surface-mount applications requiring wider thermal stability than SOT23 packages offer. It serves as a low-power alternative to two-terminal shunt references by eliminating the need for external series resistors while maintaining efficiency at various battery voltages.
Part Context
This part belongs to the MAX6120 family of voltage references manufactured by Analog Devices Inc./Maxim Integrated. While the base MAX6120 is available in a 3-pin SOT23 package, the ESA+ designation specifically identifies the 8-pin Small Outline (SO) package variant designed for surface-mount technology integration.
Replacement Considerations
For guaranteed temperature coefficients below 50ppm/°C, consult the MAX6520 data sheet. Higher-grade options with lower temperature coefficients may be available directly from the factory for the SOT23 package variant.
