3 Description
The AMC0x11D is a precision, galvanically isolated
amplifier with a 2V, high impedance input, fixed-gain,
and differential output. The high-impedance input
is optimized for connection to a high-impedance
resistive divider or other voltage signal source 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 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 AMC0x11D devices come in 8-pin, wide- and
narrow-body SOIC packages, and are fully specified
over the temperature range from –40°C to +105°C.
