MAX4265 ~ MAX4270 voltage feedback op amp circuit diagram

Published:2011/5/17 2:24:00 Author:Ecco | Keyword: voltage feedback , op amp

MAX4265 ~ MAX4270 voltage feedback operational amplifier has a low distortion, it will remain extremely low distortion in the context of the entire bandwidth of driving 100Ω load. They provide excellent spurious free dynamic range (SFDR), when the frequency is lower than 5MHz-90dBc or better; the 100MHz is-60dBc. Single power supply voltage is +4.5 ~ +8.0 V, dual power supply voltage is ± 2.25 ~ ± 4.0V. These features of MAX4265 ~ MAX4270 make them be ideal for high-performance communications and signal processing applications, because these applications require very low distortion and wide bandwidth.
