採用全差動隔離式放大器的隔離式電流和電壓量測參考設計
TIDA-00555
概覽
TIDA-00555 demonstrates the use of AMC1100, a fully differential isolation amplifier, as an analog front end to measure voltage and current. It demonstrates measurement of voltage inputs in an input-to-output isolation configuration and current inputs in a channel-to-channel isolation configuration. It includes power isolation, which makes capable of measuring isolated voltages and currents. This design can be used in applications that require replacing current transformers (CTs) with shunts. Shunts and potential dividers are provided onboard to directly connect current and voltage inputs.
