Description

The single MAX4112/MAX4113, dual MAX4117/MAX4118, and quad MAX4119/MAX4120 current feed back 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, and deliver 0.1dB gain flatness up to 115MHz and -3db bandwidths of 400MHz (AV2V/V) and 300MHz(AV8V/V), respectively. 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.

The MAX4112 has a wide output voltage swing of ±3.5V into 100Ω and a high current-drive capability of 80mA.
