3 Description

The AMC0x11D-Q1 is a precision, galvanically

isolated amplifier with a 2V, high impedance

input, and fixed-gain, differential output. The highimpedance

input is optimized for connection to highimpedance

resistive dividers or other voltage signal

sources with high output resistance.

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 AMC0x11D-Q1 outputs a differential signal that

is proportional to the input voltage. The differential

output is insensitive to ground shifts and enables

routing the output signal over long distances.

The AMC0x11D-Q1 devices come in 8-pin, wide- and

narrow-body SOIC packages, and are fully specified

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