■ 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 amplifier, converts into a digital signal through the Schmidt circuit, and drives the TTL or MOS IC directly.

■ Features

? High sensitivity and low drift

? Stable temperature characterstics due to the additional temperture 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

■ Applications

? Speed sensors

? Position sensors

? Rotation sensors

? Keyboard switches

? Microswitches
