NANJING AH ELECTRONICS CO., LTD
AH3503 SERIES LINEAR HALL-EFFECT SENSOR
Integrated circuit includes a voltage regulator, Hall-voltage generator, linear amplifier and emitter-follower
out stage. The output of the Ics change linearity with the magnetic flux density of the input.
FEATURES
. Extremely Sensitive
. Flat response to 23kHz
. Low-Noise Output
. 4.5V to 6V Operation
. Magnetically Optimized Package
TYPICAL APPLICATION
. Motion detector
. Gear tooth sensors
. Proximity detector
. Velocity detecting of motor bicycle
. Current detecting sensor

CHARACTERISTICS CURVE
Cautions
1. When install,
should as full as
possible decrease the
mechanical stress
acting on the Hall IC,
to avoid the influence
of the operate point
and release point.
2. On the premise of
ensuring welding
quality, use as
possible as low
welding temperature
an short time.
