MAX6166BESA+T

Overview

The MAX6166BESA+T is a precision, micropower, low-dropout voltage reference with a fixed output of 2.5V. It operates within an input voltage range from VOUT + 0.2V to 12.6V and features a maximum temperature coefficient of 10ppm/°C and initial accuracy of ±5mV. The device draws a typical quiescent supply current of 100µA, can source up to 5mA or sink 2mA, and includes internal compensation eliminating the need for external capacitors.

Feature Summary

• Proprietary curvature-correction circuitry ensures high stability across temperature variations
• Laser-trimmed thin-film resistors provide precise initial accuracy without requiring external components
• Internally compensated design eliminates the need for external frequency-stability capacitors

Applications

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

Procurement Notes

Verify the specific suffix 'B' indicates the required initial accuracy and temperature coefficient specifications. Confirm the '+T' designation aligns with the intended reel packaging requirements. Ensure the SO-8 package footprint matches the target board layout constraints before finalizing procurement orders.

Selection Notes

Select this component when a stable 2.5V reference is needed in space-constrained designs. The internal compensation allows for reduced bill-of-materials by removing external capacitors. Verify that the load current requirements do not exceed the specified sourcing or sinking limits for optimal performance.

Part Context

This part belongs to the MAX6161–MAX6168 family of precision voltage references manufactured by Analog Devices / Maxim Integrated. All devices in this series share identical pinouts and package styles, differing primarily in their factory-set output voltages and specific accuracy grades defined by their ordering suffixes.

Replacement Considerations

Other members of the MAX6161–MAX6168 family are pin-compatible replacements if different output voltages are acceptable. Verify that any substitute maintains the same SO-8 package dimensions and RoHS compliance status.
