GENERAL DESCRIPTION
It does not require output coupling capacitors or bootstrap capacitors. And with ultra low shutdown current, the LN3990 is ideally suited for mobile phone and other low voltage applications where minimal power consumption is a primary requirement. With special pop-click eliminating circuit, the LN3990 provides perfect pop-click characteristic during turn-on and turn-off transitions. The LN3990 is unity-gain stable and can be configured by external gain-setting resistors.● Key Specifications
