Welcome @JanhaviDeshpande, to the community!

Many details are still missing:

  • buzzer data sheet (link to the data sheet would be fine)
  • what supply voltage will the buzzer have
  • what frequencies should the buzzer emit and at what volume?
  • which waveforms should be sent to the buzzer?
  • are you planning to use an amplifier stage, if so, which one (or do you need proposals)?

Regards
/Peter

First of all, Thankyou Sir for replying to the message.

Basically, using TMB12A05 active buzzer for a project based on anamoly detection based on audio. Basic functioning includes giving alert.

Still not enough information on what you're trying to achieve.

  • "based on audio" - So do you have something that detects this audio? Microphone? Describe what this anomaly consists of.
  • The buzzer has a frequency range of 2300+/-300H. You need to have some kind of driver for it as well, which you haven't provided any schematic.

What's that?

As @Peter BENSCH said, give a link to its datasheet.
