_______________General 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 (A
V
2V/V) and 300MHz
(A
V
8V/V), respectively. Their high slew rates of up to
1800V/s provide exceptional full-power bandwidths up
to 280MHz, making these amplifiers ideal for high-per-
formance pulse and RGB video applications.
These high-speed op amps have a wide output voltage
swing of 3.5V into 100
and a high current-drive
capability of 80mA.

Note 1:
The MAX4112/MAX4113/MAX4117MAX4120 are designed to operate in a closed-loop configuration in which the IN- pin is
driven by the OUT pin through an external feedback network. If an external voltage source is connected to IN-, current into
or out of IN- must be limited to 10mA, to prevent damage to the part.
