Texas Instruments AMC0x11D/AMC0x11D-Q1 Precision Isolated Amplifiers

Texas Instruments AMC0x11D/AMC0x11D-Q1 Precision Isolated Amplifiers have a 2V, high impedance input, fixed gain, and differential 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. It is highly resistant to magnetic interference and is certified to provide basic isolation up to 3kVRMS (D package) (60s) and reinforced isolation up to 5kVRMS (DWV package).

The Texas Instruments AMC0x11D/AMC0x11D-Q1 outputs a differential signal proportional to the input voltage. The differential output is insensitive to ground shifts and enables the routing of the output signal over long distances. The AMC0x11D/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 +105°C. The AMC0x11D-Q1 devices are AEC-Q100 qualified for automotive applications.
