CS3511 Stereo 10 W High-efficiency Class-D Audio Power Amplifier Closed-loop Advanced Architecture True Spread Spectrum Modulation Premium Quality Audio Amplification 99 dB Dynamic Range - System Level THD+N 5 W - System Level -104 dB Channel Separation Four Selectable Amplifier Gain Settings Integrated Protection and Automatic Recovery for Over-current, Under-voltage, and Thermal Overload Single-supply Operation Typ. = 9-12 V No Bootstrap Capacitors Required Low-power Standby Mode Supports Differential or Single-ended Inputs Thermally Enhanced 32-pin, 6 x 6 mm QFN Package Requires No External Heat Sink Common Applications Active Speakers Portable Media Player Docking Stations Mini/Micro Shelf Systems Digital Televisions 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 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.
