PA4990
1.2W AUDIO POWER
AMPLIFIER WITH ACTIVE-LOW
SHUTDOWN MODE
DESCRIPTION
As a power amplifier which is operating on a single 5V supply,
the UTC PA4990 is capable of delivering 1.2W of output power into
8Ω loads with less than 1% distortion.
The UTC PA4990 is optimally suited for applications: Mobile
phones (cellular/cordless), notebook computers PDAs and Portable
audio devices.
The shutdown mode can reduce the supply current to less than
10nA. It also includes thermal shutdown protection internally. By
external gain setting resistors the gain can be configured.
FEATURES
* Operating: VCC=2.2V ~ 5.5V
* 1.2W output power, VCC=5V, THD=1%, f=1kHz, 8Ω Load
* In shutdown mode: Ultra-low consumption (10nA)
* In grounded mode: 62dB PSRR @ 217Hz
* POP & CLICK near-zero
* Ultra-low distortion :0.1% (typ)
