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 IC is then adjusted which keeps the internal signal
amplitude constant over the air gap range of the device. This fea-
ture provides operational characteristics independent of air gap.
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 convert-
ers 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 behav-
ior work to normalize and reduce the impact of the offset on IC
performance.
