The MAX9710ETP+T delivers 3 W per channel into a 3 Ω load from a single 4.5-5.5 V supply. That 3 Ω figure is a real-world speaker impedance — many small drivers in portable speakers and soundbars dip to 3-4 Ω at resonance — so this part drives them without the voltage headroom a higher-impedance load would need.
On-chip features that simplify the audio chain
Built-in depop circuitry suppresses the turn-on/turn-off thump that otherwise needs an external mute relay or series capacitor. The mute and shutdown pins let a microcontroller or GPIO hold the amplifier quiet during power-up sequencing, and the thermal protection shuts down the output if the die overheats — useful if the speaker impedance drops below 3 Ω momentarily.
