Medical and Industrial Imaging

The THS4303 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.

•

Power Supply Voltage: 3 V or 5 V

The devices are offered in a 16-pin leadless package

and incorporate a power-down mode for quiescent

power savings.
