Description (continued)
performance independent of air gap and also to dynamically adapt
device performance to the typical operating conditions found in
automotive applications, particularly cam sensing applications
(reduced vibration sensitivity).
High-resolution (9-bit) peak detecting DACs are used to set the
adaptive switching thresholds of the devices, ensuring high accuracy

Application
even in the presence of gear eccentricity. Hysteresis in the thresholds
reduces the negative effects of anomalies in the magnetic signal
(such as magnetic overshoot) associated with the targets used in
many automotive applications. The ATS673 and 674 also include
a low bandwidth filter that increases the noise immunity and the
signal to noise ratio of the IC.
Two options are available for output polarity, low over tooth (LT)
and high over tooth (HT). For applications requiring absolute
accuracy use the ATS674. The ATS673 should be used for targets
with high wobble.
