Information

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.

The LM48100Q 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. Comprehensive output short circuit and thermal overload protection prevent the device from being damaged during a fault condition.

A low power shutdown mode reduces supply current consumption to 0.01µA. Superior click and pop suppression eliminates audible transients on power-up/down and during shutdown. The LM48100Q is available in an 14-pin HTSSOP package
