描述 Description

The single MAX4112/MAX4113, dual MAX4117/MAX4118, and quad MAX4119/MAX4120 current feedback amplifiers combine high-speed performance with low-power operation. The MAX4112/MAX4117/MAX4119 are optimized for closed-loop gains of 2V/V or greater, while the MAX4113/MAX4118/MAX4120 are optimized for gains of 8V/V or greater.
The MAX4112/MAX4117/MAX4119 and the MAX4113/MAX4118/MAX4120 require only 5mA of supply current per channel. The MAX4113/MAX4118/MAX4120 deliver 0.1dB gain flatness up to 115MHz. The MAX4112/MAX4117 have -3dB bandwidths of 400MHz (AV > 2V/V) and the MAX4118/MAX4120 have -3dB bandwidths of 300MHz (AV > 8V/V). Their high slew rates of up to 1800V/μs provide exceptional full-power bandwidths up to 280MHz, making these amplifiers ideal for high-performance pulse and RGB video applications.
These high-speed op amps have a wide output voltage swing of ±3.5V into 100Ω and a high current-drive capability of 80mA.
