What is CCLD?

CCLD, stands for Constant Current Line Drive, means the sensor interface using Constant Current Supply.


CCLD from an accelerometer with built-in preamplifier or a microphone preamplifier enables direct connection to an FFT Analyzer without using external amplifier. 2 to 4 mA of CCLD is commonly used.


CCLD offers many benefits; [1] External amplifier is not required. [2] Two-wire system cable (coaxial cable etc.) can be used. [3] Enables cable extension longer than using the other method. [4] Cable disconnection detecting function can be added.
