DN8798MS
3 V operation Hall IC
s Overview
The DN8798MS 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.
s Features
• Wide operating supply voltage range
(V_CC = 2.7 V to 14.4 V)
• Wide operating ambient temperature (−40°C to +85°C)
• Package: Mini type (3-pin type)
(1.1 mm thick: Same as a standard transistor)
