It's a volatile pot — the wiper position resets to midscale on power-up and is lost when the supply drops — controlled via a simple Up/Down (U/D, CS) serial interface. The SOT-23-8 package keeps the footprint small, which matters when you're squeezing a volume or gain trim into a tight PCB layout. Typical applications include audio level control, LCD contrast adjustment, and programmable gain stages in industrial or consumer gear where the -40°C to 85°C temperature range covers the operating environment. ## Package and mounting The logarithmic taper is the reason you'd pick this over a linear digital pot. Human hearing is logarithmic, so a linear pot makes volume changes feel uneven — most of the adjustment happens in the first few degrees of rotation. The MAX5407EKA+T's log taper maps the 32 tap positions to a pseudo-audio curve, giving finer control at low levels and coarser steps at high levels. If you're replacing a mechanical audio pot in a preamp or active speaker, this is the digital equivalent. The 400Ω typical wiper resistance adds a small series offset that matters if you're driving a low-impedance load directly — check the load's input impedance against the wiper's contribution. ## Lifecycle and sourcing The MAX5407EKA+T is listed as Active with RoHS3 compliance. If you're looking for a pin-compatible alternative, the closest sibling is the MAX5407EKA (without the +T suffix) — same die, same package, but the +T variant is the tape-and-reel version.","metaTitle":"MAX5407EKA+T Digital Potentiometer, 20k, 32-Tap, SOT-23-8","metaDescription":"MAX5407EKA+T from Analog Devices is a 20k logarithmic digital potentiometer with 32 taps in a SOT-23-8 package.
