DN8899S

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. s Block Diagram · DN8899/SE/TE Stabilized Power Supply Temperature Correction Circuit 1 VCC 3 Output Hall Element 2 GND Amp.
