awg 18 wire
During my design ,
I need to build up the long wire model which need the parasitical parameter
(such as conductance ,resistoance, inductance,capacitance) of the AWG18 wire.
however, I can not find it, who has it ?
would you please share the data ?
Many many thanks.
5v 2a buck
Requirement is "Cost" and "Efficient" .
Here I select : LM25576 , MIC4576 , LT1766 .etc ,
However, could you tell me which one (or others) is more cheap and more
Thanks very much.
24v to 3.3v
How to deal with 24v->3.3V LDO circuit?
Goal : input : +24V~~+30V
output: 3.3V , 80mA
I plan to use "LM317" .
If I input the 24V directly to LM317's input,
then the efficiency is too low ( efficiency = Vout/vin = 3.3/24...
what is the output of MAX1036(ADC), if the analog input of ADC is bigger than its Vref?
A/D is MAX1036
if analog input is 4.096V , then it will output "11111111" ,
if analog input is 4.5V , MAX1036 will output what ? "11111111" still ???
(Note :Vcc = 5.0V )
Where Q is a generic NPN transistor, such as BC817 .
So what is the voltage of point "YYY" , if Vin = 40V ?
and what is the voltage of point "YYY" , if Vin = 20V ?
how to understand the circuit ?
when Q isin state of saturation ?
how to use bufgdll of Spartan2 fpga ?
my design includes a Top module which will call some small module and some other modules.
when i use
u1: bufgdll(clk_in,clk) ;
there errors !!!
how to use BUFGDLL ?
PC can detect that the VID / PID of AN2131Q ,
can not download program by "KEIL C"or "EZ-USB Control Panel" ,
what may be the problem ?
how to deal with it ?????????
please help me!!!
Very Very thanks!!!
