MAX6162BESA+T

Overview

The MAX6162BESA+T is a precision, low-dropout, micropower voltage reference from the MAX6161–MAX6168 series. It provides a fixed output voltage of 2.048V with an initial accuracy of ±5mV and a maximum temperature coefficient of 10ppm/°C. The device operates within an input voltage range of 2.5V 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 with capacitive loads. The component is housed in an 8-pin SO package and functions reliably across an extended temperature range of -40°C to +85°C.

Feature Summary

• Features proprietary curvature-correction circuitry and laser-trimmed thin-film resistors for high precision.
• Offers supply current virtually independent of supply voltage, eliminating the need for external biasing resistors.
• Internally compensated design removes the requirement for external compensation capacitors.
• Capable of sourcing 5mA and sinking 2mA load currents with low dropout voltage.

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 before procurement. Confirm the '+T' designation aligns with the required reel packaging format for automated assembly processes. Ensure the 8-pin SO package footprint matches the target PCB layout constraints. Validate that the operating voltage range meets the system's minimum input requirements.

Selection Notes

Select this part when a stable 2.048V reference is needed with moderate precision requirements. The B-grade variant offers wider tolerance limits compared to the A-grade version. Consider the low quiescent current for battery-operated designs where power efficiency is critical. Verify that the 5mA source capability satisfies the downstream circuit load demands without exceeding thermal limits.

Part Context

This component belongs to the MAX6161–MAX6168 family of precision voltage references manufactured by Analog Devices / Maxim Integrated. The family shares common architectural features including micropower operation and low-dropout characteristics. Variants within the series differ primarily in their fixed output voltage options and precision grades, allowing designers to choose specific values ranging from 1.25V to 5V.

Replacement Considerations

Other members of the MAX6161–MAX6168 series may serve as functional substitutes if the output voltage matches the application requirements. Cross-referencing the specific accuracy grade and temperature coefficient is necessary when replacing with different suffix variants. Ensure any alternative maintains the same 8-pin SO package dimensions for direct pin compatibility.
