Allegro MicroSystems A1260
The A1260 vertical Hall-effect sensor IC is an extremely temperature-stable and stress-resistant magnetic-sensing device ideal for harsh operating environments. The sensor is actuated by alternating north and south polarity magnetic fields in plane with the device’s branded face. Each device includes on a single silicon chip: a voltage regulator, a Hall-voltage generator, a small-signal amplifier, chopper stabilization, a Schmitt trigger, and a short-circuit protected open-drain output to sink up to 25 mA.FEATURES AND BENEFITS

DESCRIPTION
Two package options, the SOT23W surface-mount and SIP through-hole, allow sensing in a variety of orientations with respect to the mounting position. Superior high-temperature performance up to 175°C junction temperature is made possible through dynamic offset cancellation, which reduces the residual offset voltage normally caused by device overmolding, temperature dependencies, and thermal stress.
