Description
Module with the PAM8904 controller designed specifically to control piezoelectric elements. The amplifier operates over a wide frequency range, up to 300 kHz. It is a BTL (Bridge-Tied Load) system with a built-in voltage amplification system, which allows for gain up to approximately 13 Vpp.
The module requires a supply voltage of 3 to 5 V and a square wave signal with a frequency of 20 Hz to 300 kHz. There is also a DIP switch on the board to set the gain: you can select off (no gain), gain x1, x2 or x3. The amplifier has a differential output. The piezo loudspeaker is connected to the screw connector, and the control signal is connected to the STEMMA connector.
Features
- Supply voltage range from 3V to 5V
- The integrated boost converter generates voltage up to 13 V
- Input signal 20 Hz to 300 kHz
- Low power consumption
- Automatic standby and wake-up control
- Input connector: STEMMA
- Output connector: screw
- Dimensions: 22.5 x 17.7 x 10.2 mm
