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 amplifi-
er, converts into a digital signal through the Schmidt circuit,
and drives the TTL or MOS IC directly.

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.
