DESCRIPTION

· The CS3511 is a high-efficiency class-D PWM amplifier with integrated protection features and error reporting.
· It includes an on-board regulator for a 5 VDC supply to power internal low-voltage analog and digital circuitry.
· Capable of sourcing peak currents up to 2.7 A, it offers high efficiency and supports lower power supply voltages.
· Available in a 32-pin QFN package suitable for commercial grade environments (-10°C to +70°C).

FEATURES

· Closed-loop Advanced ΔΣ Architecture for enhanced audio quality.
· True Spread Spectrum Modulation reduces EMI.
· Premium audio amplification with 99 dB dynamic range and 0.025% THD+N at 5 W.
· Four selectable amplifier gain settings and integrated protection for over-current, under-voltage, and thermal overload.
· Operates on a single supply (typically 9-12 V) and requires no bootstrap capacitors.
· Supports both differential and single-ended inputs and includes a low-power standby mode.
· Thermally enhanced 32-pin QFN package eliminates the need for an external heat sink.

APPLICATIONS

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