Three integrated features simplify the audio chain. The depop circuit suppresses the audible pop and click during power-up and shutdown — no external muting FET or timing capacitor needed. Differential inputs reject common-mode noise picked up on long signal traces to the codec or DAC. The shutdown pin drops quiescent current to near zero for power-save modes in duty-cycled designs.
The MAX9788ETI+T delivers 2.4W into an 8Ω load from a single channel (mono). That rating is the maximum output power per channel at the specified load impedance.
The depop circuit ramps the output bias voltage smoothly during power-up and shutdown, eliminating the audible pop and click that occurs when the amplifier transitions between active and inactive states.
The suffix difference indicates package variant: the MAX9788ETI+T is in a 28-TQFN (5x5 mm) package, while the MAX9788ETE+T uses a different package outline. Pinout and electrical specifications are identical — the choice is purely footprint and board layout.
