Remote sensing with a switched mode power supply?
Quote:Shall it be feasible, just run in two extra potential Vcc and GND wires and use these for error amplifier inputs. IIRC this is Lead Resistance Compensation method. No extra...

USB Switch
You can use a switch like the TPS2560.

0.7V..20V wide input step up converter with 15V fixed output
Quote:look for SEPIC converter topology I haven't seen any that go as low as .7V.

Solid State Relay?
I sort of just skimmed through this thread but I think this might work. Edit: Woops, someone already suggested a Fairchild load switch that...

My professor allowed a TI89 in our circuits class. Using the matrix method with a calculator made that class a piece of cake, even with capacitors/inductors and AC circuits.

Best Pre-sensitive photoetch pcb maker
Quote:I have used board houses as well and the results are great, but it seems like you can either have quick turn-around or cheap, but not both. In the end it seems like they are...

No complaints with the MG chemicals boards. Here's a tutorial I posted on how to etch boards if you're interested: I just recently submitted my...

USB Host and Device in Original XBOX
I know the guys at work have some USB sniffing software. I personally have only used the Beagle USB analyzer, but I'm assuming that's not an option since it's expensive.

Looking for voltage reference IC, 3.3v - 5v
I ended up using an intersil reference in my design, the reason being is that it had really low quiescent current. I think the cost was pretty high compared to other parts though.

JFET maximum gain?
Thanks for the responses. We actually decided to build a small board with a microcontroller on it and a variable gain amplifier. Now if it's an AVR or PIC, that's another story...

JFET maximum gain?
I used a 10 uF bypass cap.

6-36V input, 3.3V output, and low quiescent current?
Thanks, those parts look like they will be perfect for my application.
