350mW AUDIO POWER
AMPLIFIER WITH
SHUTDOWN MODE
CMOS IC
DESCRIPTION
As a mono bridged power amplifier which is operating on a
single 5V supply, the UTC PA4819 is capable of delivering
350mWRMS of output power per channel into 16Ω loads with less
than 10% THD+N and also delivering 300mWRMS of output power
per channel into 8Ω loads with less than 10% THD+N.
The UTC PA4819 is optimally suited for low-power portable
applications because of the it do not require output coupling
capacitors, bootstrap capacitors or snubber networks.
By using external gain-setting resistors, the closed loop
response of the unity-gain stable PA4819 can be configured.
FEATURES
* Output power at 10% THD+N
Supply voltage:5V
Delivering 350mWRMS into a 16Ω load
Delivering 300mWRMS into a 8Ω load
* With shutdown mode
* Stable unity-gain.
