The DN6847/SE/TE/S is a combination of a Hall element,
amplifier, Schmitt 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 Schmitt circuit,
and drives the TTL or MOS IC directly.

■ 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 ; VCC= 4.5 to 16V)
2. Change from “H” to “L” level increases the supply current by approx. 1mA.
