TI AMC1350QDWVRQ1

The AMC1350-Q1 is an isolated precision amplifier. The output and input circuits of this amplifier are separated by an isolation barrier with extremely high electromagnetic interference resistance. This isolation barrier is certified to provide enhanced electrical isolation of up to 5 kVRMS, complies with VDE V 0884-11 and UL1577 standards, and can support an operating voltage of up to 1.5 kVRMS. The isolation barrier can separate devices operating at different common-mode voltage levels in the system and protect the low-voltage side from potentially harmful voltage surges. The high-impedance input of the AMC1350-Q1 is optimized for connection to high-impedance resistive voltage dividers or other voltage signal sources with high output resistance. It features excellent accuracy and low temperature drift, supports accurate AC and DC voltage detection, and is suitable for on-board chargers (OBC), DC/DC converters, traction inverters, or other applications that must support high common-mode voltages. The AMC1350-Q1 comes in a wide-body 8-pin SOIC package, complies with the AEC-Q100 standard for automotive applications, and supports a temperature range of -40°C to +125°C.
