LM48100Q is a single supply operation, mono, bridged load with an iamp 2 C-volume control, ideal for automotive applications. A comprehensive output fault detection system detects load conditions, short-circuit protection devices, and open-circuit conditions.
从单一5V电源工作，LM48100Q Flexible power requirements allow operation from 3.0V to 5.5V. The high power supply rejection ratio (PSRR) at 1kHz 74 dB allows the device to operate in noisy environments without the need for additional power regulation.
LM48100Q can mix/multiplex the output function of the device, dual audio inputs. Each input channel has its own independent, 32-level volume control. Mixer, volume control and device mode selection control, via I 2 C compatible interface. A fault occurred when the output indicated by the opening^ FAULT. Integrated output short-circuit and thermal overload protection prevents damage to the device in fault conditions.
The low-power shutdown mode reduces the supply current consumption to 0.01μA. Advanced click suppression eliminates transient noise heard when power-up/down and off. LM48100Q in a 14-pin TSSOP package
