MAX6141EUR+T

Overview

The MAX6141EUR+T is a low-dropout, micropower three-terminal voltage reference providing a fixed output of 4.096V. It operates within an input voltage range of 4.3V to 12.6V and maintains a typical supply current of 78µA at +25°C, increasing to 130µA across the full temperature range. The device features an initial accuracy of ±1% and a typical temperature coefficient of 15ppm/°C, guaranteed under 50ppm/°C. It is housed in a compact 3-pin SOT23 package and supports continuous operation from -40°C to +85°C.

Feature Summary

• Low dropout voltage capability ideal for battery-powered systems
• Micropower consumption with supply current independent of input voltage variations
• Stable operation with capacitive loads up to 10nF without requiring output capacitors

Applications

• Battery-powered portable equipment
• Data-acquisition systems
• Instrumentation and process control

Procurement Notes

Verify the component matches the specific 3-pin SOT23-3 package configuration and the -40°C to +85°C operating temperature range. Confirm that the ordering suffix corresponds to tape-and-reel packaging if automated assembly is required. Ensure the part number aligns with the manufacturer's latest documentation to avoid discrepancies in pinout or electrical specifications.

Selection Notes

Select this component when a fixed 4.096V reference is needed in space-constrained designs. It is suitable for applications where minimizing quiescent current is critical for extending battery life. Consider the ±1% initial accuracy and thermal stability requirements against the system's precision needs before finalizing the design.

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 (2.5V, 4.5V, 5.0V) and an adjustable version (MAX6160). All members share similar micropower characteristics and are designed for efficient operation in 3V and 5V systems.

Replacement Considerations

Other members of the MAX61xx family, such as the MAX6125, MAX6145, and MAX6150, offer identical packages and pinouts but provide different fixed output voltages. The MAX6160 provides an adjustable output but requires external resistors and uses a 4-pin SOT143 package.
