The AMC0x11R is a precision, galvanically isolated amplifier with a 2.25V, high impedance input and single-ended ratiometric 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 AMC0x11R 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 AMC0x11R 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 AMC0x11R 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.
