Product details

256-tap SPI digital pot with wide supply range

The Maxim Integrated MAX5394LATA+T is a single-channel, 10kΩ digital potentiometer with 256 wiper taps controlled via an SPI interface. The linear taper means each step changes resistance by an equal increment — suited for voltage-divider or adjustable-reference applications where the relationship between code and output is linear. The part operates from 1.7V to 5.5V, covering 1.8V logic, 3.3V, and 5V rails without needing an extra supply regulator. The wiper resistance is a typical 25Ω, and the temperature coefficient is 50ppm/°C, keeping the set point stable across temperature.

Housed in an 8-WFDFN exposed-pad package (8-TDFN-EP, 2x2 mm), the MAX5394LATA+T is a surface-mount device.

The 50ppm/°C tempco and wide supply range make it a candidate for precision bias adjustments or programmable references in those settings.

Frequently asked questions

Can I use MAX5394LATA+T for audio volume control?

The MAX5394LATA+T has a linear taper, not a logarithmic (audio) taper. For audio volume control where perceived loudness follows a logarithmic curve, a log-taper digital pot is the usual choice. A linear pot can work in a digital volume-control loop with software mapping, but the step sizes will be uneven in perceived loudness.

Does MAX5394LATA+T come in tape and reel?

Yes. The "+T" suffix in the order code indicates tape-and-reel packaging, which is the standard delivery for automated assembly.

What is the difference between MAX5394LATA+T and MAX5394LATA+?

The difference is packaging: the "+T" suffix denotes tape-and-reel, while the "+" suffix (without T) typically denotes tube or other packaging. The electrical specifications are identical.

What is the lead time for MAX5394LATA+T?

Lead time is confirmed at quote time against an RFQ. Current availability and pricing are sourced through independent distribution and provided on request.
