4.1W into 4Ω — what that means for the speaker load
The 4.1W rating into 4Ω is the maximum continuous output power per channel at the specified load and supply voltage.
Depop, differential inputs, shutdown — why they matter
The depop circuit eliminates the audible pop when the amplifier turns on or off, which is critical for battery-powered devices where the amp cycles with the audio stream. Differential inputs reject ground-loop noise picked up on long input traces — useful when the audio source is a separate codec or Bluetooth module on the same board. The shutdown pin pulls the quiescent current to near zero, extending standby life in portable gear.
WLP package — plan the assembly process
The 16-WLP package is a bare-die-scale package with solder bumps directly on the die.
