025% THD+N @ 5 W - System Level -96 dB Channel Separation General Description 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 regulator 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.
Please refer to “Ordering Information” on page 24 for complete ordering information.
