Hi Guys...

I am building a circuit using the LM3900, i am building section by section and testing as i go, i have a sinewave going into the chip at pin 3, the output at pin 4 however is severely clipped top and bottom, with the device i am using should i expect to see something similar at the output or something vastly different? i want to get each section working properly before proceeding to the next.

Severe clipping points to excessive input level. Try a much smaller input at pin 3.
 
I made my sinewave input much smaller at pin 3 and pin 4 (output) now looks REALLY nice!

Thankyou so much Alec!!

Neil.
