Underwater Transducer

[itzyfay]

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!!!

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.
