The A1301 and A1302 are continuous proportional linearHall-effect sensorsIC。 These sensors have been optimized to provide a voltage output precisely proportional to the applicable magnetic field. These devices have a quiescent output voltage equal to 50% of the supply voltage. Two output sensitivity options are available: 2.5 mV/G for the A1301 and 1.3 mV/G for the A1302.
in each deviceHall-effect integrated circuitsIncludes Hall sensing elements, linear amplifiers, and CMOS Class A output structures. Integrating Hall sensing elements and amplifiers on a single chip minimizes many of the problems typically associated with analog signals at low voltage levels.
Internal gain and offset correction adjustments have been made during manufacturing to achieve high accuracy output levels.
These features make the A1301 and A1302 preferred in position detection systems for linear target movement and rotating target movement. They are ideal for industrial applications with a wide temperature range (-40°C to 125°C).
Two device package types are available: LH, a 3-pin SOT23W type package for surface mounting; and UA, a 3-pin ultra-small SIP for via mounting, all packages are Pb-free (suffix, T) with 100% matte tin leadframe plating.
