The SOT-23-8 package is a compact footprint suited for dense PCB layouts where a through-hole trimmer would waste board area. The -40°C to 85°C temperature range covers industrial enclosures, outdoor telecom cabinets, and automotive cabin environments.
The MAX5401EKA+T carries an Active lifecycle status and is ROHS3 compliant. No end-of-life notice or last-time-buy window is in effect.
Yes, the linear taper and 256-tap resolution make it suitable for audio volume control in line-level signal paths, provided the 100kΩ end-to-end resistance and 2.7V–5.5V supply are compatible with the audio stage.
The MAX5401EKA+T is the tape-and-reel variant of the base MAX5401 in the SOT-23-8 package. Functionally identical; the suffix indicates the packaging format (EKA = SOT-23-8, T = tape-and-reel).
