UPDATE: So far, I found two (2) significant bugs: 1. +1.8V and +3.3V are swapped with respect to the pins of the chip. Brain fart. Embarrassing. 2. The clock...
Hello, Iam subin mathew and iam an electronic engineer.I do lot of projects in microcontroller.But iam interested in drawing orcad.Though i got the software,i...
Look in the Files area for the Digi-Key libraries. Some microcontroller libraries are there. For others, visit the manufacturer's web site. microsuffer...
Sorry, I just looked and told you wrong. Instead, you need to click on Links and follow the starter lib link. Lots of other stuff is in the Files section, but...
hello i am using LATB T66B osram true color led (smd topled, package P-LCC-4) Is there already a library for pcb footprint of this device ? thank you in...
This isn't the right group I suppose but I am going to throw the question out there anyway. If I have an opamp in the standard inverting configuration so that...
Define the remainder of the circuit. What are the supply rails for the op amp? At what voltage is the non-inverting input? Your description implies that the...
The invetering configuration assumes: 1) The input signal is connected to the R1 resistor. 2) The Non-inverting input must be connected to a DC Voltage signal...
Hi, Supply rails are +/-5V. Input voltage is 2.5VDC from a lab power supply applied to the "west" end of R1 as you say. The "east" end of R1 thus go to the...
Hi, There is no blocking capacitor. This is a dc coupled circuit. I described it in more detail in another email if it is not too much trouble for you to read...
R1 and R3 will form a voltage divider, which can be seen as a lower voltage input with a lower source impedance, and the two effects tend to cancel. If the...
Hi, The situation is, i repeat from you earlier mail is that the opAmp is in inverting configuration with dual supply +-5V. The gain of OpAmp is with R3 and R1...
Hi, I know about the bias current iuuses. The thing is this is an existing circuit and I have seen it work properly (no railing effects when a 100k resistor is...
I would suggest to download, install and use free simulation tool (if you don't have such module in your OrCAD) Switcher CAD from Linear Technology: ...
Believe me (I am in that business for more than 20 years now) - autorouter is not for the beginners! First you have to learn very well how to do it manually,...
WHAT???? !!! You mean i can't just push a button and get ready to build gerbers??? ; ) Yes, I would agree with the post below. I like to think of an...
Autorouter is decent for doing nets where pretty much if they make contact they are okay. What I ususally do is route critical nets by hand, these include...
hi friends i have designed one op amp based level shifter. i have drawn in ORCAD but i dont know how to compile and see the output. can any one tell me how to...
Has anybody been able to get the UltraLibrarian symbol generator that MicroChip offers on it's web page to actually generate a usable symbol in OrCAD 9.0 or...
It does work. 1. Use "Load Data Download From Microchip", to select the part you have downloaded and unzipped. 2. Select the formats you want exported...eg,...
Hi, I'm a nooby of all this, I'm doing some school projects but we are using 7 segment displays, I read many past messages about doing it yourself but I dont...
Ruben, I am not sure what you were asking for so I added a library for some seven segment and dot matrix displays and addressed your question in two other...
