A1323

The A132X family of linear Hall-effect sensors are optimized, sensitive, and tem- perature-stable. These ratiometric Hall-effect sensors provide a voltage output that  is proportional to the applied magnetic fi  eld.  The A132X family has a quiescent  output voltage that is 50% of the supply voltage and output sensitivity options  of 2.5mV/G, 3.125mV/G, and 5mV/G. The features of this family of devices are  ideal for use in the harsh environments found in automotive and industrial linear  and rotary position sensing systems.

Each device has a BiCMOS monolithic circuit which integrates a Hall element,  improved temperature-compensating circuitry to reduce the intrinsic sensitivity  drift of the Hall element, a small-signal high-gain amplifi  er, and a rail-to-rail low- impedance output stage.
