MAX6141ESA

Overview

The MAX6141ESA is a low-dropout, micropower three-terminal voltage reference providing a fixed output of 4.096V. It operates within a supply voltage range of 4.3V to 12.6V and delivers an initial accuracy of ±1%. The device features a typical temperature coefficient of 15ppm/°C, guaranteed under 50ppm/°C, with a quiescent supply current of approximately 78µA at +25°C that remains virtually independent of input voltage variations. It is housed in an 8-pin SO package and functions reliably across a temperature range of -40°C to +85°C.

Feature Summary

• Low dropout voltage capability suitable for 3V and 5V systems
• Micropower consumption with supply current independent of input voltage
• Stable operation with capacitive loads up to 10nF

Applications

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

Procurement Notes

Verify the specific part number against official manufacturer documentation to confirm pinout compatibility and electrical specifications. Ensure the operating environment falls within the specified temperature range and voltage limits. Cross-reference datasheet revisions to validate performance parameters before finalizing procurement decisions.

Selection Notes

Select this component when a fixed 4.096V reference is required with minimal power consumption. It is appropriate for designs where input voltage varies but must remain above the minimum threshold. Consider the 8-pin SO package constraints and thermal dissipation requirements relative to the application's physical layout.

Part Context

This device belongs to the MAX61xx family of low-cost, low-dropout voltage references manufactured by Analog Devices Inc./Maxim Integrated. The family includes variants with different fixed output voltages or adjustable configurations, all sharing similar low-power characteristics and package options designed for portable electronics.

Replacement Considerations

Direct substitutes within the same family include MAX6125 (2.5V), MAX6145 (4.5V), and MAX6150 (5.0V) in the 8-pin SO package. Verify that the alternative voltage level matches the system requirement.
