MAX6165BESA

Overview

The MAX6165BESA+ is a precision, low-dropout, micropower voltage reference featuring a 5.000V output with ±5mV initial accuracy and a maximum temperature coefficient of 10ppm/°C. It operates within an input voltage range of 5.2V to 12.6V, drawing a typical quiescent supply current of 120µA. The device provides up to 5mA source current and 2mA sink current, ensuring stable performance across 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, saving board space.
• Supply current remains virtually independent of the supply voltage, maximizing efficiency in battery-operated systems.

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 package type matches the SO-8 footprint requirements. Ensure the input voltage supply meets the minimum dropout requirement relative to the 5V output. Check RoHS compliance status if environmental regulations apply to the assembly process.

Selection Notes

Select this component when a fixed 5V precision reference is needed with minimal power consumption. The internal compensation simplifies layout by removing external capacitor dependencies. Consider the 10ppm/°C temperature drift limit against system accuracy requirements. Evaluate the 5mA sourcing capability against peak load demands during operation.

Part Context

This part belongs to the MAX6161–MAX6168 family of precision, micropower, low-dropout voltage references. All members share identical pinouts and general characteristics, differing primarily in their fixed output voltage options ranging from 1.25V to 5V. The family utilizes BiCMOS technology and offers consistent performance metrics across various voltage levels.

Replacement Considerations

Direct replacements include other members of the MAX6161–MAX6168 series with different output voltages if the 5V requirement changes. Verify that any substitute maintains the same SO-8 package dimensions and pin configuration to ensure mechanical compatibility without PCB redesign.

FAQ

Does the MAX6165BESA require an external output capacitor for stability?

No, the device is internally compensated and does not require an external capacitor for frequency stability, though one may be added to improve transient response.

What is the minimum input voltage required for the MAX6165BESA?

The minimum input voltage is VOUT + 0.2V, which equals 5.2V for the 5.000V output version.
