Description
The CS44L11 is a complete stereo digital-to-PWM
Class-D audio amplifier system controller including in-
terpolation, volume control, and a headphone amplifier
in a 16-pin TSSOP package.
The CS44L11 architecture uses a direct-to-digital ap-
proach 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 sys-
tems, smaller device package, less heat sink
requirements, and smaller power supplies.
The CS44L11 is ideal for portable audio, headphone
amplifiers, and mobile phones.
