※Note1) The sensor center is located within the φ0.3mm
circle.
Note2) The tolerances of dimensions with no mentions is
±0.1mm.
Note3) Coplanarity:The differnces between standoff of
terminals are max.50μm.
Note4) Shaded area is plating area
Note5) The center shadow area of the bottom of HIC
does not need to be soldered.
This area shares the lead frame with VSS inside
the package and please be careful not to short
this area to pins except No.2.
