The CS3511 is a high-efficiency Class-D PWM amplifier that integrates on-chip over-current, under-voltage, over-temperature protection, and error reporting. An onboard buck converter generates a 5 VDC supply used to power the internal low-voltage analog and digital circuitry. The low RDS(ON) outputs can source peak currents up to 2.7 A, deliver high efficiency, allow a small device package, and lower power supply voltage levels.

The CS3511 is available in a 32-pin QFN package in Commercial grade (-10°C to +70°C). The CRD3511 customer reference design is also available.
