LM48100QMH/NOPB

音频放大器 Mono 1.3W Audio Power Amplifier with Output Fault Detection and Volume Control 14-HTSSOP -40 to 105

DESCRIPON

The LM48100Q is a single supply, mono, bridge-tied load amplifier with I2C volume control, ideal for automotive applications. 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 LM48100Q delivers 1.3W of continuous output power to an 8Ω load with < 1% THD+N. Flexible power supply requirements allow operation from 3.0V 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.
