I am designing a system that will allow me to take measurements of ultrasonic sound waves with an Onda hydrophone in an underwater environment. The ultrasonic transducer will be inside a water meter. The hydrophone will be mounted to a 3D gantry system allowing me to move it precisely around...
I've got a circuit I'm trying to design and have a few questions. I'm interfacing a microcontroller to a device with an open collector output. I'm trying to design transient voltage suppression circuitry. I'm looking into using transorbs but I couldn't find any that clamp at a voltage level...
