AMC0x11S/AMC0311S-Q1 Precision Isolated Amplifiers

Texas Instruments AMC0x11S/AMC0311S-Q1 Precision Isolated Amplifiers feature a 2.25V, high-impedance input, fixed gain, and single-ended 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 3kV_RMS (D package) (60s) and reinforced isolation up to 5kV_RMS (DWV package). The Texas Instruments AMC0x11S/AMC0311S-Q1 outputs a single-ended signal proportional to the input voltage with a fixed gain of 1V/V. The output is designed to connect directly to the input of an ADC. The voltage applied to the REFIN pin sets the output voltage at 0V input. The AMC0x11S devices come in 8-pin, wide- and narrow-body SOIC packages.
