说明

The THS4303 device is a wideband, fixed-gain amplifier that offers high bandwidth, high slew rate, low noise, and low distortion. This combination of specifications enables analog designers to transcend current performance limitations and process analog signals at much higher speeds than previously possible with closed-loop, complementary amplifier designs. The devices are offered in a 16-pin leadless package and incorporate a powerdown mode for quiescent power savings.
