New Microchip programmed with 3 different ULTRASONIC frequencies. Made for use with Ultrasonic transducers and other high frequency transducers.
Outputs Three SINGLE Frequencies. This is different from our Sweep frequency IC.

• 1. 20 kHz
• 2. 22.5 kHz
• 3. 25 kHz

  Use it to drive an audio power amp, or IRF530 mosfet, or a darlington driver like ULN2803 or ULN2074 to amplify the signal. Great for experimenting with PHASOR pain field generators, dog training, etc.

  Output is a square wave which can be amplified to drive a transducer. Should use an inductor in series with the transducer, to convert the squarewave into sinewave, which drives the transducer more efficiently. Frequency accuracy is about +/- 2%.

  Can also be used as a Dog Whistle or Dog Trainer, and probably as an Insect Repellant too (since it outputs the mosquito repellant frequency). And can be used for experimenting with L R A D also.

  Phaser technology is also a basis of L RAD non-lethal weapon devices which were recently used to defend US Cruise Ship against Pirates near Somalia (Nov. 2005). .
