AMC1311BDWV Description
The AMC1311BDWV is a precision, isolated amplifier with an isolation barrier that is highly resistant to magnetic interference between the output and the input circuitry. According to VDE V 0884-11 and UL1577, this barrier is certified to provide reinforced galvanic isolation of up to 7 kV peak. This isolated amplifier separates portions of the system that run on different common-mode voltage levels and protects lower-voltage parts from damage when used in conjunction with an isolated power supply. The AMC1311BDWV's high-impedance input is designed for use with high-voltage resistive dividers and other voltage signal sources with high output resistance. In closed-loop systems, the device's exceptional performance allows for accurate, low-temperature drift voltage or temperature detection and control. The built-in detection of a missing high-side supply voltage simplifies system-level design and diagnostics.
