  I will keep this episode as my reference for op amps. As usual magnificent. 👏

  Straightforward, I must say. Great example of eliminating common mode noise.

  I built a low-distortion Wien Bridge Oscillator using a dual op-amp schematic that I found on the internet. To get this low distortion (I experimented with other dual-op-amps such as LM358 and other types, but the FET inputs on the LF353 provided the lowest level of distortion-.03% THD), and to get the proper frequency 400HZ , I utilized two .1% 10K resistors that were paralleled with two 1% 100K resistor and two .25% .04uF capacitors and a 345 lamp, (6-volt @ 40-ma) plus three other resistors (100Ω, 100K, 560K). This oscillator produced a maximum output of 7.5-VAC when powered with ± 15VDC, this output was sent to a 500-watt per channel stereo audio power amplifier in bridge-mode producing 0-150VAC @ 400HZ for powering commercial aircraft electrical components.

  THIS WAS CRAZY HELPFULL, u back to life some ideas that  i got that i thought they were too complicated (for me) or expensive, thank you, love your channel

  Such a great presentation. You show practical working ciruits with good examples (love the diff opamp substraction noise -- where you created a simple noise source as well!), the theory, the scope it all just makes so much sense and is to the point, so it's easier to reproduce and make actual practical sense. Thanks!

  It&apos;s also very important to mention rail-to-rail feature of op amps. TL082 is not a rail-to-rail op amp, so the output is not expected to fully reach Vcc/-Vcc.<br><br>Also, it would have been nice to enlist the voltage follower (a.k.a. unity gain amplifier, or isolation amplifier) which has high impedance input.<br><br>Very nice video, I also saved it :)

  Derek, if youre still out there.... I just want to say I appreciate you hosting these videos and I hope you will drop more of these gems in the future! &nbsp;I cant quite explain, but your &nbsp;lax tone/demeanor and deep knowledge of the subject really engages me and I feel I learn more from &quot;DC2Daylight&quot; than any other channel. &nbsp; You really make it feel like im learning electronics with my best friend. &nbsp; &nbsp;Cheers from Texas! and I hope youre well!
