MAX6163AESA+

Overview

The MAX6163AESA+ is a precision, micropower voltage reference featuring a 3.000V output in an 8-pin SO package. It operates within an input voltage range of VOUT + 200mV to 12.6V and delivers a typical quiescent supply current of 100μA. The device provides a source current of up to 5mA and a sink current of 2mA. Key electrical specifications include an initial accuracy of ±2mV maximum and a temperature coefficient of 5ppm/°C maximum over the -40°C to +85°C extended temperature range.

Feature Summary

• Proprietary curvature-correction circuitry combined with laser-trimmed thin-film resistors ensures high precision and stability.
• Internally compensated design eliminates the need for external compensation capacitors, reducing board space requirements.
• Supply current remains virtually independent of the supply voltage, maximizing efficiency in battery-operated systems.
• Capable of sourcing 5mA and sinking 2mA load currents while maintaining low dropout voltage characteristics.

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 required initial accuracy and temperature coefficient parameters before procurement. Confirm that the 8-pin SO package aligns with the target PCB footprint. Ensure the input voltage source can provide sufficient current during turn-on transients to guarantee reliable operation under all conditions.

Selection Notes

Select this component when a stable 3.000V reference is required with minimal power consumption. The internal compensation simplifies layout by removing external capacitor dependencies. Consider the 5mA sourcing capability for driving moderate loads directly without additional buffering stages.
