AMC1200 - Texas Instruments

AMC1200 Fully-Differential Isolation Amplifier

The AMC1200 and AMC1200B are precision isolation amplifiers with an output separated from the input circuitry by a silicon dioxide (SiO2) barrier that is highly resistant to magnetic interference. This barrier has been certified to provide galvanic isolation of up to 4250 VPEAK (AMC1200B) or 4000 VPEAK (AMC1200) according to UL1577 and VDE V 088410. Used in .
