Description
TheA3340Halleffectswitchisanextremelytemperature-stable
and stress-resistant sensor especially suited for operation
over extended temperature ranges up to 150°C. Superior
high-temperature performance is made possible through
dynamic offset cancellation, which reduces the residual offset
voltage normally caused by device overmolding, temperature
dependencies, and thermal stress.
The device includes on a single silicon chip a voltage regulator,
Hall-voltage generator, small-signal amplifier, chopper
stabilization, Schmitt trigger, and a short-circuit protected
open-collector output to sink up to 25 mA. A south pole of
sufficientstrengthwillturntheoutputoff.Anon-boardregulator
permits operation with supply voltages of 4.2 to 24 volts.
Two package styles provide a magnetically optimized package
for most applications. Suffix LH is an SOT23W surface mount
package and while suffix UA is a three-lead ultramini SIP for
through hole mounting.
The A3340 complements the A3240, which offers the same
features, but with the opposite output polarity.
