3 Description

The AMC0x11S is a precision, galvanically isolated

amplifier with a 2.25V, high impedance input, fixedgain,

and single-ended 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 AMC0x11S outputs a single-ended signal

proportional to the input voltage with a fixed gain of

1V/V. The output is designed to connect directly to the

input of an ADC. The voltage applied to the REFIN pin

sets the output voltage at 0V input.

The AMC0x11S 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.
