Datasheet DN8897SE, DN8897S, DN8897 Datasheet (Panasonic)

■ Overview

The DN8897/SE/TE/S is a combination of a Hall element,
amplifier, Schmidt circuit, and stabilized power supply/temper­ature 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

Note) This IC is not suitable for car electrical equipment.

■ Flux-Voltage Conversion Characteristics

■ Precaution on Use

1. Change of the operation magnetic flux density dose not depend on the supply voltage, because the stabilization power supply
is built-in. (only for the range ; V

CC

= 4.5 to 16V)

2. Change from “H” to “L” level increases the supply current by approx. 1mA.
