The LM48100QMH is a single supply mono bridge-tied Audio Power Amplifier with I2C volume control. 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 5V supply, the LM48100QMH delivers 1.3W of continuous output power to an 8R load with <1% THD+N. Flexible power supply requirements allow operation from 3 to 5.5V. High power supply rejection ratio (PSRR), 74dB at 1kHz, allows the device to operate in noisy environments without additional power supply conditioning. The LM48100QMH features dual audio inputs that can be mixed/multiplexed to the device output. Each input path has its own independent, 32-step volume control. The mixer, volume control and device mode select are controlled through an I2C compatible interface. An open drain FAULT output indicates when a fault has occurred.
