General Description

The MAX4180 family of current-feedback amplifiers

combines high-speed performance, low distortion,

and excellent video specifications with ultra-low-power

operation in miniature packages. They operate from

±2.25V to ±5.5V dual supplies, or from a single +5V

supply. They require only 1mA of supply current per amp-

lifier while delivering up to ±60mA of output current

drive. The MAX4180/MAX4182/MAX4183/MAX4186

are compensated for applications with a closed-loop

gain of +2 (6dB) or greater, and provide a -3dB band-

width of 240MHz and a 0.1dB bandwidth of 70MHz.

The MAX4181/MAX4184/MAX4185/MAX4187 are com-

pensated for applications with a +1 (0dB) or greater

gain, and provide a -3dB bandwidth of 270MHz and a

0.1dB bandwidth of 60MHz.

The MAX4180–MAX4187 feature 0.08%/0.03° differen-

tial gain and phase errors, a 20ns settling time to 0.1%,

and a 450V/µs slew rate, making them ideal for high-

performance video applications. The MAX4180/

MAX4181/MAX4183/MAX4185 have a low-power shut-

down mode that reduces power-supply current to 135µA

and places the outputs in a high-impedance state. This

feature makes them ideal for multiplexing applications.

The single MAX4180/MAX4181 are offered in space-

saving 6-pin SOT23 packages.
