描述 Description
The CS44L11 is a complete stereo digital-to-PWM Class-D audio amplifier system controller including interpolation, volume control, and a headphone amplifier in a 16-pin TSSOP package.
The CS44L11 architecture uses a direct-to-digital approach that maintains digital signal integrity to the final output filter. This minimizes analog interference effects that can negatively affect system performance.
The CS44L11 contains on-chip digital bass and treble boost, peak signal limiting, and de-emphasis. The PWM amplifier can achieve greater than 90 efficiency. This efficiency leads to longer battery life for portable systems, smaller device package, less heat sink requirements, and smaller power supplies.
The CS44L11 is ideal for portable audio, headphone amplifiers, and mobile phones.
