I like to announce the availability of the next video in the educational series of Operational Amplifier. Here I test the OPA37. This chip is designed for high frequency unity gain of 50 MHz. It has ultra-low noise and is a perfect fit for our scalar wave communication project. What is never told in the documentation but listed as chart is the voltage supply noise to voltage signal input over voltage gain. While it is complicated to read and understand I have provided this video to demonstrate what it means. You find the video under research and courses and in there in active components. This video is only available to all members. The next video in the making is with the LM386. This is an operational power amplifier dedicated for AM radio amplification. This will replace my guitar amplifier and is a cheap chip for one Dollar, Pound or Euro.
