DN8897/SE/TE/S
Hall IC (Operating Temperature Range
Topr=–40 to + 100˚C,
Operating in Alternative Magnetic Field)
s Overview
The DN8897/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 characterstics due to the additional tem-
perture compensator
Wide operating supply voltage range (VCC=4.5 to 16V)
Operatig in alternative magnetic field
TTL and MOS ICs directly drivable by output
Provided with the output pull-up resistors (typ 27k)
“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 car electrical equipment.
