Underwater Transducer

Underwater Transducer

Underwater Transducer

(OP)
I'm currently in the middle of building an underwater depth finder using a 200kHz pzt transducer, does anyone have any useful circuitry or hints to help me along, I plan on using a 200Khz oscillator to supply a pulser with the given signal to the transducer, any help would be great, thanks!!!

RE: Underwater Transducer

How many of these depthfinders are you making?  If a small number, may I suggest the National Semiconductor LM1812 chip.  The IC was designed for just this type of application.  Unfortunately, the component was discontinued a number of years ago but are still available from distribution.
