Maxim MAX4228EUB, MAX4228ESD, MAX4226ESDB, MAX4225ESA, MAX4224EUT-T Datasheet

_______________General Description

The MAX4223–MAX4228 current-feedback amplifiers
combine ultra-high-speed performance, low distortion,
and excellent video specifications with low-power oper­ation. The MAX4223/MAX4224/MAX4226/MAX4228
have a shutdown feature that reduces power-supply
current to 350µA and places the outputs into a high­impedance state. These devices operate with dual sup­plies 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 low­power 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 multiplex­ing applications.

The single MAX4223/MAX4224 are available in space­saving 6-pin SOT23 packages. All devices are available
in the extended -40°C to +85°C temperature range.

Note 1: The MAX422_EUT is 100% production tested at TA= +25°C. Specifications over temperature limits are guaranteed by design.
Note 2: Absolute Maximum Power Dissipation must be observed.
Note 3: Does not include impedance of external feedback resistor network.
Note 4: AC specifications shown are with optimal values of R

F

and RG. These values vary for product and package type, and are

tabulated in the

Applications Information

section of this data sheet.

Note 5: The AC specifications shown are not measured in a production test environment. The minimum AC specifications given are

based on the combination of worst-case design simulations along with a sample characterization of units. These minimum
specifications are for design guidance only and are not intended to guarantee AC performance (see

AC Testing/

Performance

). For 100% testing of these parameters, contact the factory.

Note 6: Input Test Signal: 3.58MHz sine wave of amplitude 40IRE superimposed on a linear ramp (0IRE to 100IRE). IRE is a unit of

video signal amplitude developed by the International Radio Engineers. 140IRE = 1V.

Note 7: Assumes printed circuit board layout similar to that of Maxim’s evaluation kit.
