Automatic Gain Control (AGC)
AGC allows the device to operate with an optimal internal elec-
trical signal, regardless of the air gap (within the operating signal
range specification). During calibration, the device determines
the peak-to-peak amplitude of the signal generated by the target
and automatically adjusts the signal gain. Figure 5 illustrates the
effect of this feature.
Automatic Offset Adjust (AOA)
AOA circuitry automatically compensates for the effects of chip,
magnet, and installation offsets. (For capability, see Allowable
User-Induced Differential Offset, in the Operating Characteristics
table.) This circuitry is continuously active in both calibration
mode and running mode. Continuous operation of AOA allows
the IC to compensate for offset drift and for offsets induced by
temperature variations over time.
Digital Peak Detection
A digital-to-analog converter (DAC) tracks the internal analog
voltage signal V
PROC
, and is used for holding the peak value
of the internal analog signal. In the example shown in figure 6,
the DAC would first track up with the signal and hold the upper
peak value. When V
PROC
drops below this peak value by B
OP
, the
device hysteresis, the output switches, and the DAC begin track-
ing the signal downward toward the negative V
PROC
peak. After
the DAC acquires the negative peak, the output again switches
states when V
PROC
is greater than the peak by the value B
RP
. At
this point, the DAC tracks up again and the cycle repeats. The
digital tracking of the differential analog signal allows the IC to
achieve true zero-speed operation.

Figure 5: Automatic Gain Control (AGC). The AGC function corrects for
variances in the air gap. Differences in the air gap affect the magnetic
gradient, but AGC prevents that from affecting device performance, as
shown in the lowest panel.
