www.DataSheet4U.com CS44L11 Low Voltage Class-D PWM Headphone Amplifier Features  Up to 95 dB Dynamic Range  1.8 V to 2.4 V Analog and Digital Supplies  Sample Rates up to 96 kHz  Digital Tone Control Description 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.
