com CS44210 Digital PWM Controller with Headphone Monitor Features Description The CS44210 is a complete stereo digital-to-PWM Class D audio 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 l Up to 100 dB Dynamic Range l 2.
4 V to 5.
0 V supply l Sample rates up to 96 kHz l Digital Tone Control l Programmable Digital volume control —+18 to -96 dB in 1 dB steps —3 selectable HPF and LPF corner frequencies that maintains digital signal integrity to the final output filter.
This minimizes analog interference effects that can negatively —12 dB boost for bass and treble - 1 dB step size 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 package, less heat sink requirements, and smaller power supplies.
The CS44210 provides all the controls necessary to drive higher 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.
