3 Description

The AMC0x30R-Q1 is a precision, galvanically

isolated amplifier with a ±1V, high-impedance

input and single-ended ratiometric output. The highimpedance

input is optimized for connection to a highimpedance

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 AMC0x30R-Q1 outputs a single-ended signal

proportional to the input voltage. The full-scale output

is set by the voltage applied to the REFIN pin. The

output of the AMC0x30R-Q1 is designed to connect

directly to the input of an ADC. Connect REFIN to

the same reference voltage as the ADC to match the

dynamic input voltage range of the ADC.

The AMC0x30R-Q1 comes in 8-pin, wide- and

narrow-body SOIC packages, and is fully specified

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