In each of Hall ICs, a Hall element, an amplifier circuit,
a Schmidt circuit, a stabilized power supply, and a temperature compensation circuit are integrated on a single
chip by IC technique. The Hall element output is amplified by the amplifier circuit, and converted into the corresponding digital signals through the Schmidt circuit so
that TTL and MOS IC are directly drivable.

DN8897SE
• High sensitivity and low drift
• Stabilized temperature characteristics owing to additional integration of temperature compensation circuit.
• Wide operating supply voltage range
(VCC = 4.5 V to 16 V)
• Alternating magnetic field operation
• TTL and MOS IC are directly drivable by the output.
• Equipped with an output pull-up resistor (typical 27 kΩ)
• The '0' tesla point exists within the zero-cross type hysteresis width.
