OPB350 Tube Liquid Sensor


Posted on Feb 4, 2014

The PCD3360 is a CMOS integrated circuit, designed to replace the electro-mechanical bell in telephone sets. It meets most postal requirements, with selectivity of output Tone sequences and input ringer frequencies. Output signals for a loudspeaker or for a piezo-electric (PXE) transducer are provided. No Audio transformer is required since the lo
