MAX6041AEUR-T

Overview

The MAX6041AEUR-T is a precision, low-dropout, micropower voltage reference manufactured by Analog Devices Inc. It provides a fixed output voltage of 4.096V with an initial accuracy better than 0.2% and a temperature coefficient under 15ppm/°C. The device operates from a supply voltage range of (VOUT + 0.2V) to 12.6V, drawing a maximum quiescent current of 35μA. It features ±500μA source/sink capability, stable operation with capacitive loads up to 2.2nF, and is housed in a 3-pin SOT23-3 package.

Feature Summary

• Proprietary curvature-correction circuit and laser-trimmed thin-film resistors ensure high precision
• Series-mode architecture eliminates the need for external biasing resistors
• Internally compensated design allows stability without external compensation capacitors
• Supply current remains virtually independent of input voltage variations

Applications

• Hand-Held Equipment
• Data Acquisition Systems
• Industrial and Process-Control Systems
• Battery-Operated Equipment
• Hard-Disk Drives

Procurement Notes

Verify that the ordering suffix 'T' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm the specific 'A' grade designation matches the required initial accuracy and temperature coefficient specifications for the target application environment before finalizing procurement orders.

Selection Notes

Select this component when a 4.096V reference is required within space-constrained designs utilizing the SOT23-3 footprint. It is suitable for applications demanding low power consumption and high stability across varying load conditions. Ensure the input voltage exceeds the minimum dropout requirement relative to the 4.096V output level during operation.

Part Context

This part belongs to the MAX6012/MAX6021/MAX6025/MAX6030/MAX6041/MAX6045/MAX6050 family of precision voltage references. All members share identical pinouts, package types, and core architectural features, differing primarily in their fixed output voltage levels ranging from 1.247V to 5.000V.

Replacement Considerations

Other members of the MAX60xx family (e.g., MAX6045, MAX6050) are pin-compatible but provide different output voltages. Direct substitution requires verifying that the alternative voltage level meets the system requirements.

FAQ
