MAX6062BEUR-T

Overview

The MAX6062BEUR-T is a precision, low-dropout, micropower voltage reference providing a fixed output of 2.048V. It operates within an input voltage range of 2.5V to 12.6V and functions across an extended temperature range of -40°C to +85°C. The device features a maximum initial accuracy of ±0.39% and a maximum temperature coefficient of 30ppm/°C. It typically draws 90µA of quiescent supply current with minimal variation relative to input voltage changes. The component can source up to 5mA and sink up to 2mA of load current while maintaining stability without requiring external compensation capacitors.

Feature Summary

• Proprietary curvature-correction circuitry ensures high precision and low temperature drift
• Laser-trimmed thin-film resistors provide tight initial accuracy specifications
• Internally compensated design eliminates the need for external stabilization components
• Supply current remains virtually independent of input voltage variations

Applications

• Analog-to-Digital Converter (ADC) reference inputs
• Portable battery-powered systems requiring low power consumption
• Precision measurement instruments such as digital multimeters
• GPS modules and personal digital assistants (PDAs)
• Cellular phone power management circuits

Procurement Notes

Verify the specific suffix 'BEUR' corresponds to the required accuracy grade and tape-and-reel packaging format. Confirm that the ordering increment requirements for SOT23 packages are met by the supplier. Ensure the application environment stays within the specified -40°C to +85°C operating temperature range to maintain guaranteed performance parameters.

Selection Notes

Select this part when a stable 2.048V reference is needed in space-constrained designs due to the compact SOT23-3 package. Choose the B-grade variant if the ±0.39% initial accuracy specification satisfies system tolerance requirements. Consider the low dropout voltage capability for applications where the input supply voltage is close to the desired output level.

Part Context

This component belongs to the MAX6061–MAX6068 family of precision voltage references manufactured by Analog Devices Inc./Maxim Integrated. The series offers various fixed output voltages including 1.25V, 2.048V, 2.5V, 3V, 4.096V, 4.5V, and 5V. All members share similar architectural features such as micropower operation, low dropout characteristics, and high-output current capabilities within the same small form factor.

Replacement Considerations

Direct substitutes within the same family include MAX6062AEUR-T for tighter accuracy grades or other MAX606x variants for different voltage outputs. Verify pin compatibility and thermal performance before substituting with non-family parts.
