| Hall ICs DN6847/SE/S 4.00.2 (1.0) Wide operating temperature range (-40C to +100C) Alternating magnetic field operation I Overview 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.

The variation of operating magnetic flux density does not depend on supply voltage due to its built-in stabilized power source. (VCC should be confined to the range of 4.5 V to 16 V.) 2. A supply current increases by approximately 1 mA when its output level varies from high to low.
