PA4819
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.
