MAX4112/MAX4113/MAX4117–MAX4120
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. The MAX4113/MAX4118/MAX4120 deliver
0.1dB gain flatness up to 115MHz. The MAX4112/
MAX4117 have -3dB bandwidths of 400MHz (A
V
> 2V/V)
and the MAX4118/MAX4120 have -3dB bandwidths of
300MHz (A
V
> 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-perfor-
mance 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.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

Note 1:
The MAX4112/MAX4113/MAX4117–MAX4120 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.
