MAX6041BEUR-T

Overview

The MAX6041BEUR-T is a precision series-mode voltage reference delivering a fixed 4.096V output in a miniature SOT23-3 surface-mount package. It features an initial accuracy of 0.2% and a temperature coefficient under 20ppm/°C across the -40°C to +85°C range. The device draws a maximum quiescent supply current of 35μA, which remains virtually independent of input voltage. It supports sourcing and sinking up to 500μA with a dropout voltage of 200mV at full load. Internal compensation ensures stability with capacitive loads from 0 to 2.2nF without external components.

Feature Summary

• Proprietary curvature-correction circuit combined with laser-trimmed thin-film resistors for high precision
• Supply current virtually independent of input voltage, maximizing efficiency in low-voltage systems
• Internally compensated design stable with capacitive loads up to 2.2nF, eliminating external components
• Capable of sourcing and sinking up to 500μA load current with low dropout voltage

Applications

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

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when ordering. Confirm that the 'B' grade corresponds to the required 0.2% initial accuracy specification. Ensure the operating environment stays within the specified -40°C to +85°C temperature range. Check for RoHS compliance status if required by assembly standards. Validate input voltage requirements against the minimum dropout specifications for your load conditions.

Selection Notes

Select this component when a fixed 4.096V reference is needed with high accuracy and low power consumption. It is suitable for space-constrained designs due to the SOT23-3 package. Consider the 500μA source/sink capability for driving ADCs or DACs directly. Evaluate the 200mV dropout voltage against your minimum supply rail. Compare noise performance and long-term stability against other family members if stricter dynamic requirements exist.

Part Context

This part belongs to the MAX6012/MAX6021/MAX6025/MAX6030/MAX6041/MAX6045/MAX6050 family of precision, low-power, low-dropout voltage references. All devices in this series share similar architectural features, including proprietary curvature correction and micropower operation. They are designed for battery-operated and low-voltage applications requiring high stability and minimal board space.

Replacement Considerations

Other members of the MAX6012 family offer different fixed output voltages but share identical pinouts and electrical characteristics. Verify that alternative parts match the 4.096V output requirement. Ensure replacement packages are compatible with existing footprints.
