A simple piezo transducer driver circuit or a simple piezo alarm circuit is shown in the following circuit using a NAND gate. Please note: The junction of the 0.01uF capacitor and the 33 K resistor needs to be connected to ground, which is mistakenly not indicated in the diagram. So please make sure to do this otherwise the circuit will not work.

There are two possible ways to excite the audible PZT to produce sound; by driving it with a single- ended signal (i.e., 0V to +5V) or with a bipolar signal (i.e., -2.5V to +2.5V). Figure 2illustrates the mechanical deflection about a midpoint of mechanical zero when an audible PZT is driven with a bipolar signal. Figure 2. Bipolar deflection.

Abstract: This audio application note identifies and describes the key elements in designing a driver for a piezoelectric transducer (PZT). The relationship between source impedance and sound pressure level is measured, single-ended (S/E) and bridge-tied load (BTL) driving schemes are compared and the input impedance of a PZT is characterized. Audible piezoelectric …

The desired sine voltage frequency is 11 kHz. The piezo amplifier output voltage is from -40V to +40V. Because the amp driver voltage is not meeting the required 80V, a DC bias power supply is used as shown in Figure 6. The piezo amplifier is connected in series with a 4-ohm power resistor and (also in series) with an isolated 40V DC power supply.

2.2 A BRIDGE-CONNECTED DRIVER CIRCUIT The circuit that appears in Figure 4 was developed to drive a piezoelectric actuator that requires 300 Vp-p at 80 kHz. However, it will function at any frequency down to and includ-ing DC. The sinusoidal source applies 15 Vp-p at 80 kHz to drive the amplifier pair which, in turn, drives the piezoelectric ...

In order to drive a piezo through an amplifier, you need to put a signal into the amplifier, and the maximum voltage range of that input signal needs to be within the amplifier’s input voltage range. This is typically between 1V and 5V. Output Current This is the current output of the amplifier.

Fig. 2. This piezoelectric driver circuit can deliver 10 A at slew rates of 200 V/µs. erned by resistors R1 and R2, so that the output of the PA69, which is being driven as hard as it can be, is swinging between -48 V and +48 V. Therefore, the PA69 is acting as the gate driver for the MOSFETs (X1 and X2). The output of these devices swings all the
