MAX6041BEUR+T

Overview

The MAX6041BEUR+T is a precision series-mode voltage reference delivering a fixed 4.096V output in a compact SOT-23-3 package. It features an initial accuracy of ±0.2% and a maximum temperature coefficient of 20ppm/°C across the -40°C to +85°C range. The device draws a quiescent supply current of 35μA maximum, which varies by only 0.8μA/V with input voltage changes. It supports sourcing and sinking up to 500μA load current 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
• Series-mode architecture eliminates the need for external biasing resistors required by shunt references
• Internally compensated design stable with capacitive loads up to 2.2nF, saving board space
• Supply current virtually independent of input voltage, maximizing efficiency in low-voltage systems

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 the '+B' designation corresponds to the required ±0.2% initial accuracy grade. Ensure the operating environment remains within the specified -40°C to +85°C temperature range. Check that the input voltage stays above the minimum dropout requirement relative to the 4.096V output. Validate RoHS compliance status if required by your manufacturing standards.

Selection Notes

Select this component when a stable 4.096V reference is needed in space-constrained designs. It is suitable for applications requiring both source and sink capabilities up to 500μA. Consider this part for battery-powered systems due to its low, supply-independent quiescent current. It serves as a direct replacement for other MAX6041 variants differing only in accuracy grades or packaging formats.

Part Context

This device belongs to the MAX6012/MAX6021/MAX6025/MAX6030/MAX6041/MAX6045/MAX6050 family of precision, low-power, low-dropout voltage references. All members share identical pinouts, packages, and core architectures, differing primarily in their fixed output voltages and specific accuracy grades. The MAX6041 specifically provides the industry-standard 4.096V level commonly used in ADC/DAC reference inputs.

Replacement Considerations

MAX6041AEUR+T offers the same functionality with tighter ±0.2% accuracy specifications.
