_______________General Description

The MAX4223–MAX4228 current-feedback amplifiers

combine ultra-high-speed performance, low distortion,

and excellent video specifications with low-power oper-

ation. The MAX4223/MAX4224/MAX4226/MAX4228

have a shutdown feature that reduces power-supply

current to 350µA and places the outputs into a high-

impedance state. These devices operate with dual sup-

plies ranging from ±2.85V to ±5.5V and provide a

typical output drive current of 80mA. The MAX4223/

MAX4225/MAX4226 are optimized for a closed-loop

gain of +1 (0dB) or more and have a -3dB bandwidth of

1GHz, while the MAX4224/MAX4227/MAX4228 are

compensated for a closed-loop gain of +2 (6dB) or

more, and have a -3dB bandwidth of 600MHz (1.2GHz

gain-bandwidth product).

The MAX4223–MAX4228 are ideal for professional video

applications, with differential gain and phase errors of

0.01% and 0.02°, 0.1dB gain flatness of 300MHz, and a

1100V/µs slew rate. Total harmonic distortion (THD) of

-60dBc (10MHz) and an 8ns settling time to 0.1% suit

these devices for driving high-speed analog-to-digital

inputs or for data-communications applications. The low-

power shutdown mode on the MAX4223/MAX4224/

MAX4226/MAX4228 makes them suitable for portable

and battery-powered applications. Their high output

impedance in shutdown mode is excellent for multiplex-

ing applications.

The single MAX4223/MAX4224 are available in space-

saving 6-pin SOT23 packages. All devices are available

in the extended -40°C to +85°C temperature range.
