Precision, ±250mV input, basic isolated amplifier with ratiometric single-ended output

The AMC0x00R is a precision, galvanically isolated amplifier with a ±250mV,

differential input and single-ended, ratiometric output. The

input is optimized for direct connection to a shunt resistor or other low-impedance

signal source.

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 AMC0x00R 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 AMC0x00R 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 AMC0x00R comes in 8-pin, wide- and narrow-body SOIC packages, and is

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