FEATURES  
DESCRIPTION  
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.

Output Fault Detection  
I2C Volume and Mode Control  
Input Mixer/Multiplexer  
High PSRR  
Individual 32-Step Volume Control  
Short Circuit and Thermal Protection  
Advanced Click-and-Pop Suppression  
Low Power Shutdown Mode  
Available in 14-pin HTSSOP Package  
Operating from a single 5V supply, the LM48100Q  
delivers 1.3W of continuous output power to an 8  
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.  
APPLICATIONS  
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.

KEY SPECIFICATIONS  
Output Power at VDD = 5V, RL = 8, THD+N ≤  
1% 1.3W (typ)  
Quiescent Power Supply Current at 5V 6mA  
(Typ)  
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  
PSRR at 1kHz 74dB (Typ)  
Shutdown current 0.01μA (Typ)
