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.","metaTitle":"MAX9814ETD+T Class AB Microphone Amp, AGC, 14-TDFN","metaDescription":"MAX9814ETD+T Class AB mono amplifier with AGC and microphone bias. 2.7-5.5V supply, -40 to +85°C.
