Hello,
I would want to control a piezo transducer. I use a mosfet with a PWM from a µC but my supply voltage is 5V instead of 3Vpp speficied by the datasheet of the transducer.
https://www.farnell.com/datasheets/97521.pdf
I read that it's not recommended to use a serial resistor to reduce the voltage (or a zener), can I use it simply with a nMOS and direct connection between the drain and the 5V supply ? can I consider that the transducer is simply a resistor ? (like specified in the datasheet, 3V - 3mA => 1kohms impedance ?)
Is there any recommendation that I should consider ?
regards
