Linear-taper digital pot in a TSOT-23-6 — what it is and where it fits
The Maxim Integrated MAX5472EZT+T is a single-channel, 100 kΩ digital potentiometer with 32 tap positions and a linear taper characteristic. It is configured as a potentiometer (three-terminal voltage divider) and communicates via a simple Up/Down (U/D, CS) interface, which means no serial clock or data bus — just two control lines to step the wiper up or down. The non-volatile memory stores the wiper setting on power-down, so the last position is recalled at next power-up — useful for calibration trim or offset adjustment that must survive a power cycle. The supply range spans 2.7 V to 5.25 V. The operating temperature range is -40°C to 85°C.
32 taps and 35 ppm/°C — what the ratings mean for your trim circuit
The typical temperature coefficient of 35 ppm/°C means the resistance drift is low across the -40°C to 85°C range.
Lifecycle and sourcing — active, no LTB clock ticking
The MAX5472EZT+T carries an Active product status from Maxim Integrated and is RoHS3 compliant. There is no NRND or last-time-buy notice on this part, so it remains a safe choice for new designs and production BOMs.
Package and mounting — TSOT-23-6, surface-mount only
The device is supplied in a TSOT-23-6 package, which is the thin SOT-23-6 variant. It is surface-mount only. The Tape & Reel (TR) and Cut Tape (CT) options cover both production reel quantities and prototype or low-volume builds.
