MAX6163AESA+T

Overview

The MAX6163AESA+T is a precision, micropower, low-dropout voltage reference from the MAX6161–MAX6168 series. It provides a fixed output voltage of 3.000V with an initial accuracy of ±2mV and a maximum temperature coefficient of 5ppm/°C. The device operates within an input voltage range of VOUT + 0.2V to 12.6V and draws a typical quiescent supply current of 100μA. It can source up to 5mA or sink 2mA of load current while maintaining stability without requiring external compensation capacitors.

Feature Summary

• Features proprietary curvature-correction circuitry and laser-trimmed thin-film resistors for high precision.
• Offers supply current virtually independent of supply voltage to maximize efficiency in battery-operated systems.
• Internally compensated design eliminates the need for external frequency-stability capacitors.
• Capable of sourcing 5mA and sinking 2mA load currents with low dropout voltage.

Applications

• Analog-to-Digital Converters (ADCs)
• Portable Battery-Powered Systems
• Notebook Computers
• PDAs, GPS, DMMs
• Cellular Phones

Procurement Notes

Verify the specific suffix 'A' indicates the ±2mV initial accuracy and 5ppm/°C temperature coefficient grade. Confirm the '+T' designation corresponds to the tape-and-reel packaging format rather than tube packaging. Ensure the SO-8 package code matches the required footprint dimensions for the target PCB layout.

Selection Notes

Select this component when a stable 3.000V reference is required with minimal board space due to the lack of external capacitor needs. Consider the 100μA quiescent current for power-sensitive designs. Verify that the input voltage remains above the minimum dropout requirement relative to the 3.000V output across all operating conditions.

Part Context

This part belongs to the MAX6161–MAX6168 family of precision voltage references manufactured by Analog Devices / Maxim Integrated. The family shares identical pinouts and general electrical characteristics, differing primarily in their fixed output voltage options ranging from 1.25V to 5.0V. All variants utilize an 8-pin SO package and are designed for extended industrial temperature ranges.

Replacement Considerations

Other members of the MAX6161–MAX6168 family share the same pinout and package but provide different fixed output voltages. Direct substitution requires matching the specific output voltage requirement of the application circuit.

FAQ

Does the MAX6163AESA+T require an external capacitor for stability?

No, the devices are internally compensated and do not require an external compensation capacitor for frequency stability, although an output capacitor may be used to improve transient response.

What is the maximum load current capability of the MAX6163AESA+T?

The device can typically source 5mA and sink 2mA of load current.
