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. Surface-mount assembly keeps the footprint small for space-constrained PCBs.
The manufacturer continues to produce it, and there is no last-time-buy clock running.
