Overview
The THS4303 device, produced by Texas Instruments, is a wideband, fixed-gain amplifier that offers high bandwidth, high slew rate, low noise, and low distortion. This amplifier is designed to transcend current performance limitations, enabling analog designers to process analog signals at much higher speeds than previously possible with closed-loop, complementary amplifier designs. The THS4303 is available in a 16-pin leadless package and includes a power-down mode for quiescent power savings.
