I've been posting around because I'm having some trouble with a project. My project is to read raindrops with a piezo buzzer element, but I need to amplify the signal. I got some TI OPA2228 op-amps, which were suggested to me, but somebody on another post mentioned that it isn't good with the Arduino ADC because it only reaches 3v.
where do I find a 5v op-amp, or what do I search for. Reading the spec sheets for the 2228, it seemed like the voltage output range was much higher, because it said VS = ±5V to ±15V
I'm an electronics newb, but I've been thrown into this project and need to figure it out. Does anybody have any amplifier advice?
