Hi, I was trying to work with a standard circuit based on LM2907 for freq to Voltage conversion... The ckt is available in its datasheet, in Typical Applications (Minimum Component Tachometer) [
https://www.emesystems.com/pdfs/parts/LM2907.pdf]... I am trying to replicate the ckt on a breadboard... But as soon as I connect +15V, it drops to almost 0.8V... I checked and re-checked the connections on Breadboard... Changed LM2907, 7815 regulator and even the breadboard.. Still, its the same thing... As soon as I try to connect the power to Pin 5/6 of LM2907, as required by Application Ckt, the DC supply drops to 0.8V, almost...!!
I know I am missing something and it would be difficult for anyone to guess without actually having a look at my breadboard connections... But just trying my luck, if anyone has ever faced a similar problem with LM2907...
Thanks and regards...
