AN48840B, AN48841B
Low current consumption, high sensitivity CMOS Hall IC
Alternating magnetic eld operation
(For low-speed rotation detection)
■
Overview
The AN48840B/AN48841B Series is a Hall ICs (a magnetic sensor)
which has 2 times or more sensitivity and a low current consumption of
about one ftieth compared with our conventional one.
In this Hall IC, a Hall element, a offset cancel circuit, an amplier
circuit, a sample and hold circuit, a Schmidt circuit, and output stage
FET are integrated on a single chip housed in a small package by IC
technique.
■
Features
High sensitivity (AN48840B: 6 mT max., AN48841B: 8 mT max.)
due to offset cancel circuit and a new sample and hold circuit
Small current by using intermittent action
(Average supply current: 56 A typ., Sampling period: 670 s typ.)
Small package (SMD)
CMOS inverter output (logic output form)
■
Applications
Functional operation key, Mouse,
Appliances for low-speed rotation detection
