General Description
The MAX4188/MAX4189/MAX4190 are low-power, current-feedback video amplifiers featuring fast disable/enable times and low switching transients. The triple MAX4188 and the single MAX4190 are optimized for applications with closed-loop gains of +2V/V (6dB) or greater and provide a -3dB bandwidth of 200MHz and 185MHz, respectively. The triple MAX4189 is optimized for closed-loop applications with gains of +1V/V (0dB) or greater and provides a 250MHz -3dB bandwidth. These amplifiers feature 0.1dB gain flatness up to 80MHz with differential gain and phase errors of 0.03% and 0.05°. These features make the MAX4188 family ideal for video applications
