MAX6162AESA+

Overview

The MAX6162AESA+ is a precision, micropower, low-dropout voltage reference providing a fixed output of 2.048V in an 8-pin SO package. It operates within an input voltage range from (VOUT + 200mV) to 12.6V and maintains an initial accuracy of ±2mV with a maximum temperature coefficient of 5ppm/°C. The device typically draws 100μA of supply current, which remains virtually independent of the supply voltage. It can source up to 5mA or sink 2mA of load current without requiring external compensation capacitors.

Feature Summary

• Proprietary curvature-correction circuitry combined with laser-trimmed thin-film resistors ensures high stability and low temperature drift.
• Series-mode architecture eliminates the need for external biasing resistors, offering supply current that is virtually independent of input voltage.
• Internally compensated design removes the requirement for external frequency-stability capacitors, reducing board space requirements.
• Capable of sourcing 5mA and sinking 2mA while maintaining stable operation with capacitive loads.

Applications

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

Procurement Notes

Verify the specific suffix 'A' indicates the ±2mV initial accuracy and 5ppm/°C temperature coefficient variant. Confirm the 'ESA+' designation corresponds to the lead-free, RoHS-compliant 8-pin SO package. Ensure the application requires the fixed 2.048V output level provided by this specific model within the MAX6161–MAX6168 family.

Selection Notes

Select this component when a fixed 2.048V reference is required with high precision and low power consumption. It is suitable for applications needing high output current capability compared to standard shunt references. Consider the extended temperature range and low dropout characteristics for battery-operated systems where input voltage may vary close to the output level.

Part Context

This part belongs to the MAX6161–MAX6168 series of precision, micropower, low-dropout voltage references manufactured by Analog Devices / Maxim Integrated. The series offers various fixed output voltages ranging from 1.25V to 5V, all sharing similar architectural benefits including low quiescent current and high output drive capability in an 8-pin SO package.

Replacement Considerations

Other members of the MAX6161–MAX6168 family share identical pinouts and functionality but differ in output voltage. Verify that the system does not require a different reference voltage before substituting with other variants like MAX6161 or MAX6163.
