LM4853LD/NOPB

单声道 1.5 W /立体声 300mW 功率放大器 14-WSON -40 to 85

The LM4853 is an audio power amplifier capable of delivering 1.5W typ of continuous average power into a mono 4Ω bridged-tied load BTL with 1% THD+N or 95mW per channel of continuous average power into stereo 32Ω single-ended SE loads with 1% THD+N, using a 5V power supply.

The LM4853 can automatically switch between mono BTL and stereo SE modes utilizing a headphone sense pin. It is ideal for any system that provides both a monaural speaker output and a stereo line or headphone output

Boomer audio power amplifiers were designed specifically to provide high quality output power with a minimal amount of external components. Since the LM4853 does not require bootstrap capacitors or snubber networks, it is optimally suited for low-power portable systems.

The LM4853 features an externally controlled, micropower consumption shutdown mode and thermal shutdown protection. The unity-gain stable LM4853"s gain is set by external gain-setting resistors
