The CS35L33 is an 8V class D speaker amplifier that integrates a specially designed wide bandwidth boost converter with a digital input, closed loop hybrid class D amplifier. To aid in the generation of speaker linearization and protection algorithms, the amplifier’s output voltage and current are monitored in real time and can be transmitted to an external DSP via the audio/data serial port (ADSP). For easy system integration, the CS35L33 is highly programmable via a fully functional I²C control port.
