±5-V input, precision voltage sensing reinforced isolated amplifier

The AMC1350 is a precision, isolated amplifier with an output separated from

the input circuitry by an isolation barrier that is highly resistant

to magnetic interference. This barrier is certified to provide

reinforced galvanic isolation of up to 5 kVRMS according

to VDE V 0884-11 and UL1577, and supports a working voltage of up to

1.5 kVRMS.

The isolation barrier

separates parts of the system that operate on different common-mode

voltage levels and protects the low-voltage side from potentially

harmful voltages and damage.

The high-impedance input of the AMC1350 is optimized for connection to

high-impedance resistive dividers or other voltage signal sources

with high output resistance. The excellent accuracy and low

temperature drift supports accurate AC and DC voltage sensing in

DC/DC converters, frequency inverters, AC motor, and servo-drive

applications over the extended industrial temperature range from

–40°C to +125°C.
