3 Description
The AMC0x02D is a precision, galvanically isolated
amplifier with a ±50mV, differential input and
differential output. The input is optimized for direct
connection to a shunt resistor or other low-impedance
signal source.
The isolation barrier separates parts of the system
that operate on different common-mode voltage
levels. The isolation barrier is highly resistant to
magnetic interference. This barrier is certified to
provide reinforced isolation up to 5kVRMS (DWV
package) and basic isolation up to 3kVRMS (D
package) (60s).
The AMC0x02D outputs a differential signal
proportional to the input voltage. The differential
output is insensitive to ground shifts and enables
routing the output signal over long distances.
The AMC0x02D comes in 8-pin, wide- and narrowbody
SOIC packages, and is fully specified over the
temperature range from –40°C to +125°C.
