HALL IC
S-5711A Series
The S-5711A Series, developed by CMOS technology, is a Hall IC with a
high-sensitivity and operates on a low current.
The output voltage changes when the S-5711A Series detects the intensity
level of flux density. Using the S-5711A Series with a magnet makes it
possible to detect the open/close state in various devices.
High-density mounting is possible by using the super-small SNT-4A, SOT-
23-3 packages. Also, the S-5711A Series is the most suitable for portable
devices due to the low current consumption.
