Ratiometric rail-to-rail output
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 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-fre-
quency 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 recoverability after temperature cycling. Having the Hall element
and an amplifier on a single chip minimizes many problems normally associated
with low-level analog signals.
Output precision is obtained by internal gain and offset trim adjustments made at
end-of-line during the manufacturing process.
The A132X family is provided in a 3-pin single in-line package (UA) and a 3-pin
surface mount package (LH).
