CS3817BEO

CS3817BEO is a 15W (per channel) stereo high-efficiency Class D audio power amplifier. Advanced EMI suppression technology allows inexpensive ferrite bead filters at the output port to meet EMC requirements. An internal DC detection circuit provides speaker protection by shutting down the output stage when input capacitor failure or input short circuit is detected. The CS3817BEO can drive stereo speakers with loads as low as 4Ω, achieving up to 90% efficiency, eliminating the need for additional heatsinks during music playback. The CS3817BEO is suitable for LCD TVs and consumer audio equipment.
