CHOPPER-STABILIZED, PRECISION
HALL-EFFECT SWITCH
The A3240-- Hall-effect switch is an extremely temperature-stable
and stress-resistant sensor especially suited for operation over extended
temperature ranges to +150擄C. Superior high-temperature performance
is made possible through dynamic offset cancellation, which reduces the
residual offset voltage normally caused by device overmolding, tempera-
ture 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 sufficient strength will turn the output on. An
on-board regulator permits operation with supply voltages of 4.2 to 24
volts.

Three package styles provide a magnetically optimized package for
most applications. Package type LH is a modified SOT23W surface-
mount package, LT is a miniature SOT89/TO-243AA transistor package
for surface-mount applications; while UA is a three-lead ultra-mini-SIP
for through-hole mounting. The LH and UA packages are also available
in a lead (Pb) free version (suffix,

, with a 100% matte tin plated
leadframe.
