Audio Amplifier  
General Description  
Key Specifications  
n Mono-BTL output power  
The unity gain stable LM4916 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 1.5V supply, the mono BTL mode delivers  
85mW into an 8load at 1% THD+N. In Single Ended stereo  
headphone mode, the amplifier delivers 14mW per channel  
into a 16load at 1% THD+N.

With the LM4916 packaged in the MM and LLP packages,  
the customer benefits include low profile and small size.  
These packages minimize PCB area and maximizes output  
power.  
Features  
n Single-cell 0.9V to 2.5V battery operation  
n BTL mode for mono speaker  
n Single ended headphone operation with coupling  
capacitors  
The LM4916 features circuitry that reduces output transients  
("clicks" and "pops") during device turn-on and turn-off, an  
externally controlled, low-power consumption, active-low  
shutdown mode, and thermal shutdown. Boomer audio  
power amplifiers are designed specifically to use few exter-  
nal components and provide high quality output power in a  
surface mount package.  
n Unity-gain stable  
n "Click and pop" suppression circuitry  
n Active low micropower shutdown  
n Low current, active-low mute mode  
n Thermal shutdown protection circuitry  
Applications  
n Portable one-cell audio products  
n Portable one-cell electronic devices
