PA4990 CMOS IC
1.2W AUDIO POWER AMPLIFIER WITH ACTIVE-LOW SHUTDOWN MODE
DESCRIPTION
FEATURES
PA4990 CMOS 集成電路
1.2W 音頻功率放大器，帶有主動低關閉模式
描述
UTC PA4990 是一款運行於單5V電源的功率放大器，能夠在8Ω負載下輸出1.2W功率且失真率小於1%。UTC PA4990 尤其適用於以下應用：手機（無線/蜂窩），筆記本電腦，個人數碼助理 (PDA) 和便攜音頻設備。關閉模式下，供電電流可以減少到小於10nA。內部還包含熱關閉保護功能。通過外部增益設置電阻，可以配置增益。

PA4990 CMOS IC
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.
