I have a TL071cp which according to the data sheets is an opamp, which I also remember reading about when reading about the lm317 I think.
And a TC1427 which according to the data sheets is a 1.2A high speed MOSFET driver used for powering mosfets, switch mode power supply or small motor controls. While studying mosfets voltage regulators I remember reading something about smps. Could I use this as a voltage regulator or current regulator?
I already ordered a few components but have not yet received them:
LM317 - voltage regulator
AMC7135 - current regulator
pc817 - someday i plan to work with an optocoupler
tl082 - opamp
4n35 - opamp
So I could use the tl071cp to amplify the sound of a heartbeat for example
I saw this in the data sheet:
but the chip looks like this:
So should I use the diagram on the left or the one on the right?
