Description
The A132X family of linear Hall-effect sensors are optimized, sensitive, and temperature-stable.These ratiometric Hall-effect sensors provide a voltage output that is proportional to the applied magnetic field. 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 amplifier, and a rail-to-rail low- impedance output stage.
A proprietary dynamic offset cancellation technique, with an internal high-frequency clock, reduces the residual offset voltage normally caused by device overmolding, temperature dependencies, and thermal stress. The high frequency clock allows for a greater sampling rate, which results in higher accuracy and faster signal processing capability.This technique produces devices that have an extremely stable quiescent output voltage, are immune to mechanical stress, and have precise
