The CS44L10 is a complete, stereo, digital-to-PWM, digital power, audio amplifier system controller including interpolation, volume control, and a headphone amplifier in a 16-pin TSSOP package. The CS44L10 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 CS44L10 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 size, less heat sink requirements, and smaller power supplies. The CS44L10 is ideal for portable audio, headphone amplifiers, and mobile phones.
