Isolation amplifier

Isolation amplifiers are indispensable components for signal conditioning. There are several reasons that make galvanic potential isolation necessary. Examples for this are personal protection, on the one hand, as required in medical engineering to ensure contact of persons with life-threatening voltages. On the other hand, different safety aspects, such as protection of IT systems may require the use of an isolation amplifiers. If ground loops need to be separated or if a small differential voltage with a high common-mode level must be determined, the isolation amplifier is the device of your choice.

Isolation amplifier
DC-1.7 MHz | 20 V/μs |  IMRR > 106 dB |500 V_AC, 1 kV_DC

_l      3-port isolation amplifier (input, output, USB/network) with optionally selectable
input and output potentials
