(Note 1) Not to exceed Pd

(Note 2) Mounted on 24mm x 20mm x 1.6mm glass epoxy board. Reduce 1.00mW per 1°C above 25°C

Caution: Operating the IC over the absolute maximum ratings may damage the IC. The damage can either be a short circuit between pins or an open circuit

between pins and the internal circuitry. Therefore, it is important to consider circuit protection measures, such as adding a fuse, in case the IC is operated over

the absolute maximum ratings.

(Note 3) B = Magnetic Flux Density

1mT=10Gauss

Positive (“+”) polarity flux is defined as the magnetic flux from south pole which is direct toward to the branded face of the sensor.

After applying power supply, it takes one cycle of period (T_P) to become definite output.
