Description
DN8899/SE/TE/S
Hall IC (Operating Temperature Range Topr=–40 to+ 100˚C, Operating in Alternative Magnetic Field)
s Overview
The DN8899/SE/TE/S is a combination of a Hall element,
amplifier, Schmidt circuit, and stabilized power supply/temper-
ature compensator integrated on an identical chip by using the
IC technology. It amplifies Hall element output at the amplifi-
er, converts into a digital signal through the Schmidt circuit,
and drives the TTL or MOS IC directly.
s Features High sensitivity and low drift Stable temperature characteristics due to the additional tem-
perature compensator Wide operating supply voltage range(VCC=4.5 to 16V) Operating in alternative magnetic field TTL and MOS ICs directly drivable by output Semipermanent service life due to no contact parts Small change of the operating flux density against mechani-
cal stress Output open collector “0” gauss point in the zero cross type hysteresis width
s Applications Speed sensors Position sensors Rotation sensors Keyboard switches Microswitches
Note) This IC is not suitable for the car electric equipment.
