MAX5466EUK

Overview

The MAX5466EUK+T is a single-channel digital potentiometer IC from the FleaPoT family, manufactured by Analog Devices / Maxim Integrated. It features a 10 kOhm resistance value with a linear taper and 32 taps for precise adjustment. The device operates on a 2-wire serial interface and supports supply voltages of 3.3 V or 5 V. Key electrical parameters include a temperature coefficient of 35 ppm/°C, a tolerance of 25%, and a typical operating current of 25 uA. It utilizes volatile brush memory and functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Single-pot configuration with 32 adjustable taps
• 2-Wire serial digital interface for control
• Low power consumption with 25 uA operating current
• Compact SOT-23-5 surface-mount package

Applications

• Battery-powered portable devices requiring low standby current
• Audio volume control applications using linear taper
• Voltage reference trimming in measurement systems
• Gain setting in instrumentation amplifiers

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as indicated in official documentation. Check for specific ordering suffixes that may affect packaging or tape-and-reel specifications. Ensure the supplier provides valid traceability data for quality assurance purposes.

Selection Notes

Select this component when a single digital potentiometer with 32 steps is required in a minimal footprint. The 10 kOhm resistance and linear taper suit general-purpose voltage division tasks. Verify that the system voltage aligns with the 3.3 V or 5 V operational limits. Consider the volatile memory characteristic if power-down state retention is not needed.

Part Context

This part belongs to the MAX5466 series of ultra-small, low-power digital potentiometers. It shares the FleaPoT form factor with other members like the MAX5467 and MAX5468, differing primarily in resistance values and tap counts. The EUK suffix denotes the SOT-23-5 package variant suitable for space-constrained PCB designs.

Replacement Considerations

Direct substitutes include MAX5467EUK+T and MAX5468EUK+T from the same series, provided the resistance and tap count differences are acceptable for the circuit design. Cross-reference with DS1866 series parts only if pin compatibility and interface protocols allow for functional adaptation.
