Hi, I'm new to power management and am currently designing circuits to manage 12v power input from adapter. The voltage coming out of wall is around 12v and I want to use OPA743 to buffer it. Can I use this 12v power input to both power up OPA743 and to use as signal input so that I can get a 12v at output? If not, is there any buffer amplifier you suggest me to use instead? Thank you!
