1GHz, Low-Power, SOT23,
Current-Feedback Amplifiers with Shutdown
_______________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.
