DESCRIPTION

· The CS3511 is a high-efficiency class-D PWM amplifier integrating over-current, under-voltage, and over-temperature protection with error reporting.

· It features an on-board regulator generating a 5 VDC supply for internal low-voltage analog and digital circuitry.

· The amplifier can source peak currents up to 2.7 A, ensuring high efficiency, compact device packaging, and lower power supply voltage levels.

· Available in a 32-pin QFN package for commercial grade applications (-10°C to +70°C).

FEATURES

· Closed-loop Advanced ΔΣ Architecture for superior audio quality.

· True Spread Spectrum Modulation reduces EMI.

· Premium Quality Audio Amplification with 99 dB Dynamic Range, 0.025% THD+N at 5 W, and -104 dB Channel Separation.

· Four selectable amplifier gain settings for flexible audio output control.

· Integrated protection with automatic recovery for over-current, under-voltage, and thermal overload.

· Single-supply operation typically from 9-12 V, eliminating the need for bootstrap capacitors.

· Low-power standby mode and support for differential or single-ended inputs.

· Thermally enhanced 32-pin, 6 x 6 mm QFN package that requires no external heat sink.

APPLICATIONS

· Ideal for active speakers, portable media player docking stations, mini/micro shelf systems, and digital televisions.
