1.4 W mono Class AB — what it delivers
The Maxim Integrated MAX9716EUA+ is a mono Class AB audio amplifier rated for 1.4 W into a 4 Ω load from a single 2.7 V to 5.5 V supply. That 1.4 W figure is the headline — it tells you the part can drive a small speaker or piezo transducer in a portable or fixed-line application without needing a boost converter. The differential input architecture rejects ground-loop noise common in battery-powered and mixed-signal boards, and the integrated depop circuitry suppresses the turn-on thump that otherwise annoys the end user. The part is housed in an 8-pin uMAX-EP/uSOP-EP with an exposed pad for thermal dissipation. The industrial temperature range (-40°C to 85°C) covers outdoor telecom panels, factory-floor audio indicators, and automotive cabin modules that do not require AEC-Q100 qualification. Surface-mount assembly keeps the footprint small for space-constrained PCBs.
Active lifecycle — no LTB pressure
The MAX9716EUA+ carries an Active lifecycle status. The manufacturer continues to produce it, and there is no last-time-buy clock running. For a BOM line that needs a reliable mono audio amp, this part can be specified into new designs without worrying about near-term obsolescence. Sourced through independent distribution, availability and pricing are confirmed at quote time.
