Unique Features
Based on mixed signal CMOS technology, the SS559 is a Hall-effect device with high magnetic sensitivity. This
multi-purpose latch meets most of the application requirements.
The chopper-stabilized amplifier uses switched capacitor technique to suppress the offset generally observed with Hall
sensors and amplifiers. The CMOS technology makes this advanced technique possible and contributes to smaller chip
size and lower current consumption than bipolar technology. The small chip size is also an important factor to
minimize the effect of physical stress. This combination results in more stable magnetic characteristics and enables
faster and more precise design.
The wide operating voltage from 2.5V to 24V, low current consumption and large choice of operating temperature
range according to “L”, and “E” specification make this device suitable for automotive, industrial and consumer
applications.
