MAX6162AESA+T

Overview

The MAX6162AESA+T is a precision, micropower voltage reference delivering a fixed output of 2.048V in an 8-pin SO package. It operates within an input voltage range of 2.5V to 12.6V and maintains an extended temperature range from -40°C to +85°C. The device features a maximum initial accuracy of ±2mV and a temperature coefficient of 5ppm/°C. Typical quiescent supply current is 100μA with a maximum of 120μA. It supports sourcing up to 5mA and sinking up to 2mA of load current.

Feature Summary

• Proprietary curvature-correction circuitry combined with laser-trimmed thin-film resistors ensures high precision and stability across the operating temperature range.
• Series-mode architecture provides supply current virtually independent of input voltage, eliminating the need for external biasing resistors required by shunt references.
• Internally compensated design removes the requirement for external compensation capacitors, reducing component count and board space.
• Capable of sourcing 5mA and sinking 2mA while maintaining low dropout voltage characteristics suitable for battery-operated systems.

Applications

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

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging rather than tube packaging when ordering. Confirm the 'A' designation corresponds to the ±2mV initial accuracy and 5ppm/°C temperature coefficient specifications. Ensure the input voltage source can provide transient currents during turn-on to guarantee reliable operation.

Selection Notes

Select this part for applications requiring a stable 2.048V reference with minimal power consumption. The series-mode topology offers superior efficiency compared to shunt references as it does not waste current through a series resistor. Verify that the load requirements do not exceed the 5mA sourcing or 2mA sinking limits to maintain specified regulation performance.

Part Context

This component belongs to the MAX6161–MAX6168 family of precision voltage references manufactured by Analog Devices / Maxim Integrated. All members share identical pinouts, package styles, and core architectural features, differing primarily in their fixed output voltage options ranging from 1.25V to 5V.

Replacement Considerations

Other members of the MAX6161–MAX6168 family are pin-compatible replacements if different output voltages are acceptable. Cross-reference with other Maxim Integrated series-mode references only if electrical parameters such as quiescent current and accuracy meet the specific application requirements.
