DESCRIPTION
The LM4819 is a mono bridged power amplifier that
is capable of delivering 350mWRMS output power into
a 16load or 300mWRMS output power into an 8
load with 10% THD+N from a 5V power supply.
The LM4819 Boomer audio power amplifier is
designed specifically to provide high quality output
power and minimize PCB area with surface mount
packaging and a minimal amount of external
components. Since the LM4819 does not require
output coupling capacitors, bootstrap capacitors or
snubber networks, it is optimally suited for low-power
portable applications.
The closed loop response of the unity-gain stable
LM4819 can be configured using external gain-setting
resistors. The device is available in WSON, VSSOP,
and SOIC package types to suit various applications.
