19-1221; Rev 3; 8/01
Single/Dual/Quad, 270MHz, 1mA, SOT23,
Current-Feedback Amplifiers with Shutdown
General Description
Features
ꢀ Ultra-Low Supply Current: 1mA per Amplifier
ꢀ Shutdown Mode
Outputs Placed in High-Z
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
±±.±25 to ±2.25 dual supplies, or from a single ꢀ25
supply. They require only 1mA of supply current per amp-
lifier while delivering up to ±ꢁ0mA of output current
drive. The MAX4180/MAX418±/MAX4183/MAX418ꢁ
are compensated for applications with a closed-loop
gain of ꢀ± (ꢁdB) or greater, and provide a -3dB band-
width of ±40MHz and a 0.1dB bandwidth of 70MHz.
The MAX4181/MAX4184/MAX4182/MAX4187 are com-
pensated for applications with a ꢀ1 (0dB) or greater
gain, and provide a -3dB bandwidth of ±70MHz and a
0.1dB bandwidth of ꢁ0MHz.

(MAX4181/MAX4184/MAX4185/MAX4187)
ꢀ 450V/µs Slew Rate
ꢀ Fast, 20ns Settling Time to 0.1%
ꢀ Excellent Video Specifications
Gain Flatness to 70MHz
(MAX4180/MAX4182/MAX4183/MAX4186)
0.08%/0.03° Differential Gain/Phase
The MAX4180–MAX4187 feature 0.08%/0.03° differen-
tial gain and phase errors, a ±0ns settling time to 0.1%,
and a 4205/µs slew rate, making them ideal for high-
performance video applications. The MAX4180/
MAX4181/MAX4183/MAX4182 have a low-power shut-
down mode that reduces power-supply current to 132µA
and places the outputs in a high-impedance state. This
feature makes them ideal for multiplexing applications.
