1.1W AUDIO POWER AMPLIFIER

WITH SHUTDOWN MODE



DESCRIPTION

As a mono bridged power amplifier which is operating on a single

5V supply, the UTC PA4871 is capable of delivering 1.1W of output

power per channel into 8Ω loads with less than 0.5% THD+N.

The UTC PA4871 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 PA4871 can be configured.


