Description
The CS44210 is a complete stereo digital-to-PWM Class D au-
dio amplifier system controller including interpolation, volume
control, half bridge PWM driver outputs, and an integrated
CS44L10 headphone amplifier in a 24-pin TSSOP package.
The CS44210 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 CS44210 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 CS44210 provides all the controls necessary to drive high-
er voltage output stages for increased power levels.
The CS44210 is ideal for integrated, mult-function systems
such as shelf-top audio systems, audio mini systems, audio
video receivers (AVR), boom boxes and powered speakers.
