LM4913  
2W Monaural, 90mW Stereo Headphone Audio Amplifier  
General Description  
Key Specifications  
The unity-gain stable LM4913 is both a mono differential  
output (for bridge-tied loads, or BTL) audio power amplifier  
and a single-ended (SE) stereo headphone amplifier. Oper-  
ating on a single 5V supply, the mono BTL mode delivers 2W  
(typ) to a 4Ω load (Note 1) at 0.3% THD+N. In SE stereo  
mode, the amplifier will deliver 90mW to 32Ω loads. The  
LM4913 features circuitry that suppresses output transients  
("clicks and pops").

Micro-power shutdown supply current  
The LM4913 is designed for notebook and other handheld  
portable applications. It delivers high quality output power  
from a surface-mount package and requires few external  
components. The LM4913 is pin and functionally compatible  
with the TPA0213.

The LM4913 is available in a space efficient 10-lead  
exposed-DAP TSSOP package.  
Note 1: When operating on a 5V  
supply, an LM4913MH that has been  
DC  
properly mounted to a circuit board will deliver 2W into 4Ω. See the Applica-  
tion Information sections for further information concerning PCB layout sug-  
gestions to maximize the LM4913MH’s output power with a 4Ω load.

n Gain set with external resistors  
n Space-saving exposed-DAP TSSOP package  
Applications  
n PDAs  
n Cellular phones  
n Handheld portable electronic devices
