PowerPAD is a trademark of Texas Instruments.
The THS4302 device is a wideband, fixed-gain amplifier thatoffers 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.
