CS44L10

www.DataSheet4U.com CS44L10 Digital PWM Headphone Monitor Features Description The CS44L10 is a complete stereo digital-to-PWM Class D 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 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 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 package, less heat sink requirements, and smaller power supplies. The CS44L10 is ideal for portable audio, headphone amplifiers, and mobile phones. l Peak signal soft limiting l De-emphasis for 32 kHz, 44.1 kHz, and 48 —Channel A: R, L, mono (L + R) / 2, mute —Channel B: R, L, mono (L + R) / 2, mute kHz l Selectable outputs for each channel including l PWM PopGuard® l 100 mW/Channel into 16 Ω @ 3.6 V ORDERING INFORMATION CS44L10-KZ -10 to 70 °C 16-pin TSSOP SCL/DIF0 SDA/DEM Control Port VL Multibit...
