MAX6064AEUR-T

Overview

The MAX6064AEUR-T is a precision, micropower voltage reference featuring a fixed 4.096V output in a 3-pin SOT23 package. It operates within an input voltage range of 4.296V to 12.6V and supports a maximum supply current of 125µA. The device provides an initial accuracy of ±0.2% and maintains a temperature coefficient of 20ppm/°C across the -40°C to +85°C extended temperature range. It can source up to 5mA and sink 2mA of load current without requiring external compensation capacitors.

Feature Summary

• Proprietary curvature-correction circuit with laser-trimmed thin-film resistors for high stability
• Series-mode architecture eliminates the need for external biasing resistors
• Internally compensated design removes the requirement for external compensation capacitors
• Stable operation with capacitive loads while maintaining low dropout voltage

Applications

• Analog-to-Digital Converters (ADCs)
• Portable Battery-Powered Systems
• Precision 3V/5V Systems

Procurement Notes

Verify the specific 'A' grade suffix ensures the required ±0.2% initial accuracy specification. Confirm that the application input voltage remains above the minimum dropout threshold of VOUT + 200mV to maintain regulation. Ensure the power supply can provide transient currents during turn-on if operating near minimum voltage limits.

Selection Notes

Select this component when a stable 4.096V reference is needed in space-constrained designs utilizing the SOT23-3 footprint. It is suitable for battery-operated systems due to its ultra-low quiescent current and independence from supply voltage variations. Consider the 20ppm/°C drift limit for applications requiring strict thermal stability over the industrial temperature range.
