Description
The CS44L10 is a complete stereo digital-to-PWM Class D au-
dio 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 pack-
age, less heat sink requirements, and smaller power supplies.
The CS44L10 is ideal for portable audio, headphone amplifi-
ers, and mobile phones.
