Pinning is shown viewed from branded side.
The A3260-- Hall-effect bipolar switch is an extremely
temperature-stable and stress-resistant sensor IC especially suited for
operation over extended temperature ranges 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 constant-current open-collector output. A south
pole of sufficient strength will turn the output OFF. An on-board
regulator permits operation with supply voltages of 3.5 to 24 volts.
Noise radiation is limited by control of the output current slew rate.
The first character of the part number suffix determines the device
operating temperature range; suffix ‘E–’ is -40°C to +85°C and ‘L–’ is
-40°C to +150°C. Two package styles provide a magnetically opti-
mized package for most applications. Suffix ‘–LH’ is a miniature
SOT23W low-profile surface-mount package, while suffix ‘–UA’ is a
three-lead ultra-mini-SIP for through-hole mounting.

1Certain variants cited in this footnote are in production but have been determined to be LAST TIME BUY. This classification
indicates that the product is obsolete and notice has been given. Sale of this device is currently restricted to existing
customer applications. The variants should not be purchased for new design applications because of obsolescence in the
near future. Samples are no longer available. Status date change October 31, 2006. Deadline for receipt of LAST TIME BUY
orders is April 27, 2007. These variants include: A3260ELHLT and A3260EUA. Variants A3260LLHLT and A3260LUA are
discontinued.
