MAX6162BESA

Overview

The MAX6162BESA+ is a precision, micropower, low-dropout series voltage reference providing a fixed output of 2.048V. It operates within an input voltage range of 2.5V to 12.6V and delivers up to 5mA source current or 2mA sink current. The device features a maximum initial accuracy of ±5mV and a temperature coefficient of 10ppm/°C. Quiescent supply current is typically 100µA with minimal variation across the operating range. It functions reliably from -40°C to +85°C in an 8-pin SO package.

Feature Summary

• Proprietary curvature-correction circuitry ensures high stability over temperature variations
• Laser-trimmed thin-film resistors provide precise initial accuracy without external components
• Low dropout design allows operation with minimal headroom between input and output voltages
• Internally compensated architecture eliminates the need for external compensation capacitors

Applications

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

Procurement Notes

Verify the specific suffix code against the manufacturer's selector guide to confirm the exact initial accuracy and temperature coefficient grades available for this part number. Ensure the ordering information matches the required performance specifications for your application before procurement.

Selection Notes

Select this component when a stable 2.048V reference is needed with low power consumption. Consider the B-grade specifications for tighter tolerance requirements compared to A-grade options. Evaluate the load regulation characteristics under varying source and sink conditions to ensure compatibility with downstream circuitry.

Part Context

This device 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 capabilities, differentiated primarily by their fixed output voltage levels and packaging configurations.

Replacement Considerations

Other members of the MAX6161–MAX6168 series may serve as alternatives if different output voltages are acceptable. Verify pin compatibility and thermal performance when substituting with similar series references from the same manufacturer.
