A comprehensive output fault detection system senses the load conditions, protecting the device during short circuit events, as well as detecting open circuit conditions. Operating from a single 5-V supply, the LM48100QQ1 delivers 1.3 W of continuous output power to an 8 Ω load with < 1% THD+N. Flexible power supply requirements allow operation from 3 V to 5.5 V. High power supply rejection ratio (PSRR), 74 dB at 1 kHz, allows the device to operate in noisy environments without additional power supply conditioning. The LM4...
