3 Description

The AMC0x00D is a precision, galvanically isolated

amplifier with a ±250mV, 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 AMC0x00D 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 AMC0x00D comes in 8-pin, wide- and narrowbody

SOIC packages, and is fully specified over the

temperature range from –40°C to +125°C.
