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.

Evaluation board

THS4302EVM — THS4302 Evaluation Module

This EVM is used for testing the THS4302. It is fully populated, ready for testing-just add power, signal source, and monitoring instruments. The gain is not configurable as the THS4302 is internally configured for a fixed gain of +5. Thus, SMA connector is only to the non-inverting input. The (...)
