ation amplifier ISO100 composition. Optocoupler will select three channels and three-way choice coupled to the programmable gain amplifier, three channels select the optional 23 8 signals. 8-channel data acquisition system input signal after amplification by the PGA100 choose to output isolation amplifiers, after ISO100 isolation amplifier output. As a result of a variety of isolation, the circuit shown in FIG excellent anti-jamming performance for noisy applications (such as industrial field signal acquisition).
