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 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 AMC0x30R-Q1 outputs a single-ended signal

that is proportional to the input voltage. The fullscale

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 ADC's dynamic input voltage range.

The AMC0x30R-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.
