AN48820A

Hall ICs AN48820A Low current consumption, high sensitivity CMOS Hall IC Operate by the value of magnetic flux density, regardless of polarity 0.40+0.10 -0.05 0.10 M 3 1.50+0.25 -0.05 The AN48820A is a Hall IC (a magnetic sensor) which has 2 times or more sensitivity and a low current consumption of about one three-hundredth compared with our conventional one. In this Hall IC, a Hall element, a offset cancel circuit, an amplifier circuit, a sample and hold circuit, a Schmidt circuit, and output stage FET are integrated on a single www.DataSheet4U.com chip housed in a small package by IC technique. 0.65±0.15 ■ Overview Unit: mm (1.45) 1 0.95 0.95 1.90±0.20 +0.20 2.90-0.05 2 0.65±0.15 2.80+0.20 -0.30 1.10+0.20 -0.10 ■ Features Either North nor South magnetic pole can be selected * High sensitivity (6 mT max.) due to offset cancel circuit and a new sample and hold circuit Small current by using intermittent action (Average supply current: 3.5 µA typ.)
