CS44L11 Low Voltage Class-D PWM Headphone Amplifier Up to 95 dB Dynamic Range V to V Analog and Digital Supplies Sample Rates up to 96 kHz Digital Tone Control 3 Selectable HPF and LPF Corner Frequencies 12 dB Boost for Bass and Treble - 1 dB step size Programmable Digital Volume Control +18 to -96 dB in 1 dB steps Peak Signal Soft Limiting De-emphasis for 32 kHz, kHz, and 48 kHz Selectable Outputs for Each Channel, including Channel A R, L, mono L + R / 2, mute Channel B R, L, mono L + R / 2, mute PWM 23 mW/Channel into 16 V The CS44L11 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 CS44L11 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 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 systems, smaller device package, less heat sink requirements, and smaller power supplies. The CS44L11 is ideal for portable audio, headphone amplifiers, and mobile phones.
