DN8797MS
3 V operation Hall IC
I
Overview
The DN8797MS-A is a 3 V operation Hall IC which
includes a Hall element, amplifier circuit, Schmidt circuit,
stabilized power supply and temperature compensation
circuit which are integrated on a single chip with a fine
patterning technology. The magnetic input signal is out-
putted by being converted to high or low. We have im-
proved the conventional circuit to realize a stable opera-
tion covering from low to high supply voltage and from
low to high temperature.
