Driving high frequency piezo devices (100 kHz – 20 MHz), on the other hand, requires precise matching of the device impedance to the amplifier output. This can be achieved to an acceptable degree of accuracy using an adjustable impedance matching device or by designing a custom matching circuit. Piezo Linear Amplifier The EPA-104 is a high voltage (±200 Vp), high current (±200 mA), and high frequency (DC to 250 KHz) amplifier designed to drive higher capacitive (low impedance) loads, such as low voltage stacks, at moderate frequencies; or lower capacitive loads, such as. Piezo elements come in handy when you need to detect vibration or a knock. You can use these for tap or knock sensors pretty easily by reading the voltage on the output. They can also be used for a very small audio transducer such as a Buzzer. The trick is the preamp – a basic circuit used to match the piezo’s signal.
Some piezoelectric devices are operating only at resonant frequency. An example of these devices is Langevin Ultrasonic Transducers for ultrasonic washing and cleaning applications. At the piezo resonant frequency, these devices’ impedance are actually resistive as opposed to capacitive. These resonant pzt devices often specified operating power rather than voltage. For example, a resonant piezo transducer specified 16 ohm resistance at resonant frequency and the maximum operating power is 32 watts. The TS200 or TS250 ultrasonic amplifier can output up to ~70 watt.
To chose a piezoelectric amplifier, select the TS250/TS200 model that outputs the highest current using Table 1 above. The highest current is calculated by the piezo amp’s maximum voltage divided by the resonant resistance, or the peak resistive output current in Table 1, whichever is the lowest. For example, for a 16 ohm high-frequency piezo transducer, chose the TS250-2 (+/-30V). The maximum current is 30V/16ohm = 1.875A. The peak power is 56.25 watts (1.875A*30V = 56.25W). The RMS power is 28.1W. It is calculated by the RMS current times the RMS voltage (Equation 5). The RMS current is the RMS voltage divided by piezoelectric resonant resistance.
