ICL7135 PCB Layout Method
I have design a PCB layout for a 4.5 digit voltmeter using the ICL7135 chip, and i have problems with the analog and digital ground. Do you know if somebody have make a PCB...
Mains Stability and Supply Regulation
I have problem with my power supply… . The power supply uses LM317 and TIP2955 and the unstable AC net here causes the output to drop sometimes below 5V. The normally output is 13,5V....
Spice Simulation for CD4060
I found your web site today. I am looking for the CD4060 spice model for Orcad Capture. My Orcad version is the 9.2 (complete but without CD4060 !!) I saw on your web pages...
