■ 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 27kΩ)

• “0” gauss point in the zero cross type hysteresis width

■ Applications

• Speed sensors

• Position sensors

• Rotation sensors

• Keyboard switches

• Microswitches
