MAX4188/4189/4190 low-power current feedback amplifier has the low conversion transient state and high-speed enable / disable time. Three pieces of MAX4188 and single MAX4190 have closed-loop gain with +2 (6dB) or greater compensation to provide 200MHz-3dB bandwidth and 185MHz bandwidth respectively. Three pieces of MAX4189has closed-loop gain with +1 (0dB) or greater compensation to provide 250MHz-3dB bandwidth. The 0.1dB gain flatness of these amplifiers can reach 80MHz, differential gain is 0.03% and phase error is 0.055, all of these features make it be an ideal choice for video applications.
