Each device includes: a voltage regulator, two Hall transduc-
ers, temperature compensating circuitry, a low-level ampli-
fier, bandpass filter, Schmitt trigger, and an output driver. The
on-board regulator permits operation with supply voltages from
4.0 to 26.5 V. The output stage can switch 20 mA over the full
frequency response range of the device, and is compatible with
CMOS logic circuits.
The devices in this family differ from each other in their
switchpoint specifications and their switching polarity. The
A1421 has a small hysteresis and asymmetrical switchpoints,
with one switchpoint at the zero-crossing. The A1422 has a small
hysteresis and symmetrical switchpoints, both near the zero-
crossing. The A1423 offers high vibration immunity, by means
of its larger hysteresis that establishes symmetrical switchpoints
