LM48100Q  
Mono, 1.3W Audio Power Amplifier with Output Fault  
Detection and Volume Control  
General Description  
Key Specifications  
The LM48100Q is a single supply, mono, bridge-tied load  
amplifier with I2C volume control, ideal for automotive appli-  
cations. A comprehensive output fault detection system sens-  
es the load conditions, protecting the device during short  
circuit events, as well as detecting open circuit conditions.  
■ꢀOutput Power at VDD = 5V,  
RL = 8Ω, THD+N 1%  
1.3W (typ)  
■ꢀQuiescent Power Supply Current  
at 5V  
6mA (typ)  
74dB (typ)  
Operating from a single 5V supply, the LM48100Q delivers  
1.3W of continuous output power to an 8load 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 environ-  
ments without additional power supply conditioning.  
■ꢀPSRR at 1kHz  
■ꢀShutdown current  
0.01μA (typ)  
Features  
Output Fault Detection  
I2C Volume and Mode Control  
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 con-  
trol 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 cir-  
cuit and thermal overload protection prevent the device from  
being damaged during a fault condition.  
Input Mixer/Multiplexer  
High PSRR  
Individual 32-Step Volume Control  
Short Circuit and Thermal Protection  
Advanced Click-and-Pop Suppression  
A low power shutdown mode reduces supply current con-  
sumption to 0.01µA. Superior click and pop suppression elim-  
inates audible transients on power-up/down and during  
shutdown. The LM48100Q is available in an 14-pin TSSOP  
package
