Op-Amp's, Open Loop Gain, Output Phase Reversal, Infinite Input impedance, Zero Output Impedance, Infinite Gain... Do you know what all these refer to, if not then start watching.<br /><br />This is the first of a series called TI Tuesdays where I will showcase a different TI product each week (On A Tuesday). This can be anything from a small component to a full blown evaluation board or system. Either way TI sells it.<br /><br />I will be covering ADCs, DACs, I2C and SPI Isolators, LED controllers, Boost and Buck converters, Launchpads, Booster Packs, Oh and probably Beaglebone (Pick your colour) as it runs on a TI Sitara Processor too :).<br /><br />I am kicking off the series by looking at the TI TL082 JFet op-amp along with the TI Application Report from a while back. The nice thing is the report is as applicable today as it was when written back in 2001. (Analogue basics have not changed much)<br /><br />I will be using the TL082 to show how Op-Amps work and to demonstrate a few peculiarities of JFet and other varieties, particularly the Phase Reversal or the output. I will take you through Open Loop Gain, the 3 principles of the Ideal Op-Amp that make life so much easier by simplifying the calculations needed to model the device. There will only be one video in the Ti Tuesdays regarding this Op-Amp but the walk through the Application Report will continue as it provides so much wealth of information as to how the lowly op-amp works and I think there are so many people that would like to understand.<br /><br />If there is a TI component you would like me to add to the list of components to present on TI Tuesdays, leave a comment and I will see what I can do.<br /><br />Lastly, I would like to thank TI for supporting me with this endeavour. They have graciously sent me many varied products to use for the series and I look forward to sharing them with you all.<br /><br />On May 29th 2016 I am also kicking off a TI IoT week where there will be a video every day building an IoT enabled device that can be part of a home automation or monitoring system. I will be adding to the basic controller each day and by the end of the week we will have a working IoT device monitoring Temperature, Light, and possibly Humidity, sending the data to the Cloud and responding to commands from a master controller based on the BBB.<br /><br />Here is the link to "Handbook of Operational Amplifier Applications", <a href="http://www.ti.com/lit/an/sboa092a/sboa092a.pdf" target="_blank" rel="nofollow">http://www.ti.com/lit/an/sboa092a/sboa092a.pdf</a><br /><br />and the TL082 technical PDF <a href="http://www.ti.com/lit/ds/symlink/tl082-n.pdf" target="_blank" rel="nofollow">http://www.ti.com/lit/ds/symlink/tl082-n.pdf</a><br />See you there.<br />...<br /><a href="https://www.youtube.com/watch?v=g-53jY7TjO8" target="_blank" rel="nofollow">https://www.youtube.com/watch?v=g-53jY7TjO8</a>
