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.
