Product details

What the 10kΩ / 32-tap combination means for the BOM

The MAX5429EUA+ is a single-channel, linear-taper digital potentiometer. It presents a 10 kΩ end-to-end resistance divided into 32 equal tap positions. The wiper resistance is a typical 100 Ω. The part stores the wiper setting in non-volatile memory.

Board layout is straightforward — two supply pins, two control inputs, and the three potentiometer terminals (H, W, L). The package is surface-mount only; no through-hole option.

Lifecycle and compliance — no sourcing surprises

The part is ROHS3 compliant.

Frequently asked questions

Is MAX5429EUA+ RoHS compliant?

Yes, it is ROHS3 compliant.

Is MAX5429EUA+ a non-volatile digital potentiometer?

Yes, the wiper setting is stored in non-volatile memory and is retained after power is removed.

What is the difference between MAX5429 and MAX5427?

Both are single-channel digital potentiometers in the same package and pinout. The MAX5429 uses a linear taper; the MAX5427 uses a logarithmic taper. The MAX5429 is the right choice for linear adjustment applications like voltage dividers and op-amp bias, while the MAX5427 is intended for audio volume control where a logarithmic response matches human hearing.

What is the closest pin-compatible alternative to MAX5429EUA+ in this component family?

The MAX5427EUA+ is pin-compatible and shares the same package and supply range. The key difference is taper: the MAX5429 is linear, the MAX5427 is logarithmic. If the application requires a linear taper, the MAX5429 is the correct choice; if audio volume control is needed, the MAX5427 is the alternative.
