Description
The AMC0x11D-Q1 is a precision, galvanically isolated amplifier with a 2V, high impedance input, and fixed-gain, differential output. The high-impedance input is optimized for connection to high-impedance 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 AMC0x11D-Q1 outputs a differential signal that is proportional to the input voltage. The differential output is insensitive to ground shifts and enables routing the output signal over long distances.
The AMC0x11D-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.
