I have design Amplifying a Piezo Speaker and Volume Control as bellow picture.
But I need lowest cost for this design.
So could you tell me What is Opamp (single power) I can replace LM358 with lowest cost.
Thank And Best Regard.
Hello Hoang Anh,
Start here at all op amps
Select supply voltage on web page. Then click red view parts button.
On right side click approximate price twice to sort lowest to highest.
The lowest price result that is not based on LM358 core is the RC4558.
If you can lower supply voltage to 5V, then the LM321LV becomes an option.
