Two-Wire, Differential, Vibration-Resistant Sensor

with Speed and Direction Output

ATS699LSN

in the internal A-to-D range to allow for acquisition of signal

peaks. AOA and AGC function separately on the two differential

signal channels.

Start-Up Detection/Calibration

When power is applied to the ATS699, the sensor IC inter-

nally detects the profile of the target. The gain and offset of

the detected signals are adjusted during the calibration period,

normalizing the internal signal amplitude for the air gap range of

the device.

Direction information is available after calibration is complete.

For the –xxxBx variant, the output becomes active at the end of

calibration. Figure 10 shows where the first output edges may

occur for various starting target phases.

The Automatic Gain Control (AGC) feature ensures that opera-

tional characteristics are isolated from the effects of installation

air gap variation.

For the –xxxPx variant, output pulses of t_w(ND)are supplied dur-

ing calibration.

Automatic Offset Adjustment (AOA) is circuitry that compen-

sates for the effects of chip, magnet, and installation offsets. This

circuitry works with the AGC during calibration to adjust V_PROC

Figure 11 shows where the first output edges may occur for vari-

ous starting target phases.
