MAX6164BESA

Overview

The MAX6164BESA+ is a precision, micropower, low-dropout voltage reference featuring a fixed output of 4.096V. It operates within an input voltage range from VOUT + 200mV to 12.6V and delivers up to 5mA source current or 2mA sink current. The device utilizes proprietary curvature-correction circuitry and laser-trimmed thin-film resistors to achieve a maximum initial accuracy of ±5mV and a temperature coefficient of 10ppm/°C (max). Quiescent supply current is typically 100µA with minimal variation across the operating range.

Feature Summary

• Proprietary curvature-correction circuit ensures high stability over temperature variations
• Low dropout voltage allows operation with minimal headroom between input and output
• Micropower design maintains efficiency with virtually supply-independent quiescent current
• Internally compensated architecture eliminates the need for external compensation capacitors

Applications

• Analog-to-Digital Converters (ADCs)
• Portable Battery-Powered Systems
• Notebook Computers
• PDAs, GPS, DMMs
• Cellular Phones

Procurement Notes

Verify the specific suffix code against official documentation to confirm the exact initial accuracy and temperature coefficient grade. Confirm package type and RoHS compliance status directly with the manufacturer or authorized distributors before procurement. Ensure input voltage requirements align with system constraints.

Selection Notes

Select this component when a stable 4.096V reference is required in space-constrained designs. The SO-8 package minimizes board area by removing the need for external capacitors. Evaluate load regulation requirements, as sourcing and sinking currents exhibit different voltage drift characteristics under varying loads.

Part Context

This part belongs to the MAX6161–MAX6168 family of precision voltage references. All members share identical pinouts, package styles, and core architectural features, differing primarily in their fixed output voltage levels and associated accuracy grades. This family targets applications requiring high performance in low-power environments.

Replacement Considerations

Other members of the MAX6161–MAX6168 series may serve as functional replacements if the specific output voltage requirement differs but the package and electrical interface remain compatible.
