The input is optimized for direct connection to a shunt resistor or other lowimpedance signal source. The isolation barrier separates parts of the system that operate on different mon-mode voltage levels. The isolation barrier is highly resistant to magnetic interference. This barrier is certified to provide reinforced isolation up to 5k VRMS (DWV package) and basic isolation up to 3k VRMS (D package) (60s). The AMC0x02R 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 AMC0x02R 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 AMC0x02R es in 8-pin, wide- and narrowbody SOIC packages, and is fully specified over the temperature range from - 40°C to +125°C.
