I am using that Buffer as a component for impedance matching before amplifying a signal from an acoustic sensor. The issue is that I wanted to test the component using a power supply to power it (+15v), using the a similar circuit without any resistor or capacitor :
No, I am using a regular power supply with + - and ground. Does this work with regular power supply ? I am willing to put this component in a pcb that will be powered using batteries... But still couldn't make it work!
For help, you need to provide more information. Please post a link to the data sheet for the acoustic sensor, the amplifier and a schematic of your circuit.
Please explain why you think you need an impedance match.
The (minimal) sensor data sheet is in the @zaki_HDne's cross post:
The sensor appears to be a rather simple ultrasound piezoelectric transducer and given the microscopic amount of information in the data sheet, is obviously designed to be used in conjunction with the company's other products, not as a DIY component.
Most likely it is sold as a replacement part for the company's inspection and testing systems.
Product blurb:
Nevertheless, acceptance of AE as inspection and testing method was driven by integrity inspection of pressure vessels. Application of AE measurement spread from testing a pressure vessel to corrosion testing of flat bottom storage tanks (above ground storage tanks), leakage testing of pipelines and valves, testing for partial discharge in transformers, and nowadays finds its entrance in structural health monitoring of civil engineering structures.
