Product details

14-TDFN package, 3×3 mm — thermal pad integration

The MAX9814ETD+T comes in a 14-WFDFN exposed-pad package, supplier device package 14-TDFN measuring 3×3 mm. The reel (TR) or cut-tape (CT) option lets you order for prototype or production volume without changing the BOM line.

This Class AB mono amplifier integrates an AGC loop, microphone bias, and a shutdown pin — three functions that otherwise take separate op-amps and passives. The supply range covers single Li-ion through 5 V regulated rails, so it fits battery-powered recorders and USB audio front-ends alike.

Active production — ROHS3, no successor on record

No official successor or NRND notice is published — this is a current-catalog part for new designs. Sourced per RFQ through authorized and independent channels; availability and pricing confirmed at quote time. The tape-and-reel packaging matches standard pick-and-place feeders.
