Pins Definition and Description

Unique Features

Based on mixed signal CMOS technology, SS1438 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 tempera-

ture range according to “L”, “K”and “E” specifications make this device suitable for automotive, industrial and

consumer applications.
