Overview
The DN8797MS is a 3 V operation Hall IC which
includes a Hall element, amplifier circuit, Schmidt circuit,
stabilized power supply and temperature compensation cir-
cuit which are integrated on a single chip with a fine pat-
terning technology. The magnetic input signal is output-
ted by being converted to high or low. We have improved
the conventional circuit to realize a stable operation cov-
ering from low to high supply voltage and from low to
high temperature.
