DESCRIPTION
The THS4302 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. This device is offered in a 16-pin leadless
package and incorporates a power-down mode for
quiescent power savings.
