APPLICATION INFORMATIONS
A 1
μ
F (or greater) capacitor is required between
the AIC1722 output and ground for stability.
Without this capacitor the part will oscillate. Even
though most types of capacitor may work, the
equivalent series resistance (ESR) should be held
to 5
or less if Aluminum electrolytic type is used.
Many Aluminum electrolytics have electrolytes
that freeze at about -30
°
C, so solid tantalums are
recommended for operation below -25
°
C. The
value of this capacitor may be increased without
limit.
A 0.1
μ
F capacitor (or greater) should be placed
from the AIC1722 input to ground if the lead
inductance between the input and power source
exceeds 500nH (approximately 10 inches of trace).

| AIC1722-37CZL | Monitors for pressurized leaks in joints, vessels, seals, and gaskets. Because of the nature of pipework, this device is able to pick up the sonic signature of leaks from several meters away from the source. |
| AIC1722-37CZT | Monitors the ultrasonic sound components of click-to-fit assembly components which can be more reliable than relying on audible sound, especially in noisy industrial environments. |
