Doc No. TA4-EA-06129 Revision. 1 AN48841B 1.8 V Supply voltage, Low current consumption, high sensitivity CMOS Hall IC Operates for Alternating magnetic field directions FEATURES DESCRIPTION High sensitivity (8 mT max) due to offset cancel AN48841B is a Hall IC (a magnetic sensor) for circuit and a new sample and hold circuit. 3.0 V supply voltage by using Bi-CMOS technology. Small current by using intermittent action. In this Hall IC, a Hall element, a offset cancel (average supply current : 56 A typ. sampling circuit, an amplifier circuit, a sample and hold cycle : 670 s typ at V = 3.0 V) circuit, a Schmidt circuit, and output stage FET are CC integrated on a single chip housed in a small Power supply voltage : 2.5 to 5.25 V package by LSI technique. Operating ambient temperature : 25 to + 75 C High sensitivity due to offset cancel circuit and a CMOS inverter output. (no pull-up resistance) new sample and hold circuit gives you the benefits Wheel keys / Track ball applications. by use of low cost magnet. Magnetic fields polarity change from S to N or Small current by using intermittent action gives from N to S can be detected. you the benefits by low power consumption. Contactless switch in various moving devices to involve reliabilities and dusty circumstances. 5 pin Plastic Small Surface Mount Package. (SMINI Type) APPLICATIONS Magneto-electric conversion switch.
