TRUE ZERO-SPEED GEAR TOOTH SENSOR
SENSOR OPERATION: AUTOMATIC GAIN CONTROL (AGC
)
The patented self-calibrating circuitry is unique. After each power up, the device measures the peak-to-peak magnetic
signal. The gain of the sensor is then adjusted which keeps the internal signal amplitude constant over the air gap range of
the device. This feature provides operational characteristics independent of air gap.

SENSOR OPERATION: OFFSET ADJUST
In addition to normalizing performance over air gap, the gain control circuitry also reduces the effect of chip, magnet, and
installation offsets. This is accomplished using two D/A converters that capture the peak and valley of the signal and use it
as a reference for the switching comparator. If induced offsets bias the absolute signal up or down, AGC and the dynamic
DAC behavior work to normalize and reduce the impact of the offset on sensor performance.
