s Overview
The DN6849/SE/TE/S is a combination of a Hall element,
amplifier, Schmitt 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 Schmitt 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 (V
CC
=4.5 to 16V)
Operating in alternative magnetic field
TTL and MOS ICs directly drivable by output
Output open collector
s Applications
Speed sensors
Position sensors
Rotation sensors
Keyboard switches
Microswitches
Note) This IC is not suitable for car electrical equipments.

s Flux-Voltage Conversion Characteristics
s Precaution on Use
1. Change of the operation magnetic flux density does 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.
