The A3240-- Hall-effect switch is an extremely temperature-stable
and stress-resistant sensor especially suited for operation over extended
temperature ranges to +150¡ãC. 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 sufficient strength will turn the
output on. An on-board regulator permits operation with supply voltages
of 4.2 to 24 volts.
The first character of the part number suffix determines the device
operating temperature range; suffix ¡®E¨C¡¯ is for -40¡ãC to +85¡ãC and
¡®L¨C¡¯ is -40¡ãC to +150¡ãC. Three package styles provide a magnetically
optimized package for most applications. Suffix ¡®¨CLH¡¯ is a modified
SOT23W surface-mount package, ¡®¨CLT¡¯ is a miniature SOT89/TO-
243AA transistor package for surface-mount applications; while suffix
¡®¨CUA¡¯ is a three-lead ultra-mini-SIP for through-hole mounting.
