MM1969		MM1969 contains a low noise operational amplifier with a spiral inductor. This inductor detects a magnetic field generated when AC current flows through the power line. MM1969 amplifies the detected electromotive force with the built-in low noise operational amplifier (the gain can be set by changing external resistance), and transmits analog signals to an external ADC and microcontroller. This makes it possible to detect AC current in a non-contact manner.	-40	85	3	5.5	0.42	1	SOP-8G	PDF product catalog
