DESCRIPTION

The THS4302 device is a wideband, fixed-gain ampli-

fier that offers high bandwidth, high slew rate, low

noise, and low distortion. This combination of specifi-

cations enables analog designers to transcend cur-

rent performance limitations and process analog sig-

nals 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.
