TI AMC1351QDWVRQ1

The AMC1351-Q1 is an isolated precision amplifier. The output and input circuits of the amplifier are separated by an isolation barrier with extremely strong anti-electromagnetic interference performance. This isolation barrier is certified to provide enhanced electrical isolation of up to 5 kVRMS, complying with the 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 AMC1351-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, enabling precise DC voltage detection, and is suitable for DC/DC converters, inverters, motor drives, or other applications that must support high common-mode voltages. The AMC1351-Q1 comes in a wide-body 8-pin SOIC package, meets the AEC-Q100 standard for automotive applications, and supports a temperature range of -40°C to +125°C.
