Cirrus Logic CS44800
The CS44800 is a multi-channel digital-to-PWM Class D audio system controller including interpolation, sample rate conversion, half- and full-bridge PWM driver outputs, and power supply rejection feedback in a 64-pin LQFP package.The architecture uses a direct-to-digital approach that maintains digital signal integrity to the final output filter, minimizing analog interference effects which negatively affect system performance. The CS44800 integrates on-chip digital volume control, peak detect with limiter, de-emphasis, and 7 GPIO’s, allowing easy interfacing to many commonly available power stages. The PWM amplifier can achieve greater than 90% efficiency.
