Amc1311dwvr soic-8 CMTI isolation amplifier in stock
3 description
Amc1311 is an isolated precision amplifier. The output and input circuits of this amplifier are separated by isolation barriers with strong anti electromagnetic interference performance. According to VDE V 0884-11 and ul1577 standards, the barrier is certified to provide enhanced electrical isolation up to 7kvpeek. When used in combination with isolated power supply, the isolation amplifier can separate the devices of the system operating at different common mode voltage levels and prevent the damage of lower voltage devices.
The high impedance input of amc1311 is optimized for connecting high-voltage resistance voltage divider or other voltage signal sources with high output resistance. The device has excellent performance and supports accurate low-temperature drift voltage or temperature detection and control in the closed-loop system. The integrated high side supply voltage loss detection function can simplify system level design and diagnosis.
Amc1311 offers two performance level options: the rated extended industrial temperature range of amc1311b is – 55 ° C to + 125 ° C, and amc1311 is – 40 ° C to + 125 ° C.
