Hi Friends,
I have a simple question
input 12v -> time delay of 1 second -> output 12v
input gnd -> output gnd
I need a simple circuit that can do this. ofcourse with mcu its simple but need a simple solution with analog ic
Thank you
Dear Sir,
I have already solved the problem of the timing part using 555 in mono stable mode. I can adjust my time delay as required and can trigger it . its working fine. solved this part [Set_Output(1);delay(1000);Set_Output(0);] (with 1 555, 2 capacitor, 1 resistor)
my problem is much...
Hi friends,
I have been braking my head the entire day to solve this simple problem.
1) 1 digital input low/high (will be continuous say if its low then it can be low for days and vice versa)
2)output needs to be high for n seconds and should be low when the input changes.
if I need to do...
Dear Sir,
I have tired muxing 4 lines of 4 sim card as binary tree. but the design is getting much complex than I expected.
you mentioned other multiplexers what are the other options that you suggest Sir.
the devices like below...
Dear Sir,
You mean to say that I can tie up gnd, reset, clk, io together and switch Vcc alone. is that what you mean ?
Will that work?
or I need to use some package like the below

Hi Friends,
I have the following doubts regarding interfacing multiple sim cards with a single sim300 module.
As you know sim card has the following pins
1 Vcc
2 Reset
3 CLK
4 Gnd
5 Vpp (not used)
6 I/O
In my case I need to use 32 sim cards with a single SIM300. Meaning only one sim...
Hi Friends,
My question is very simple.
Input : 230V 50 Hz AC (India)
Output : 48V 5A
Please help me how can I do the above. I expect a usage of Solid State Devices for conversion. I have no idea where can start.
I am aware of commercial solutions but i need to design it for my...
I have a fuel sensor in the bus which gives me 0-200 ohms.
The fuel gauge is connected to it and it works on 24V.
so the problem is i need an ADC to be connected to it. IF i connect the ADC device 0-5V (no idea on what is the potential divider in it)alone it works or gauge alone it works.
I...
Thanks for the helping me out
just tell me whether i have got it clear or not
GB is the point where the magnitude plot cuts o dB line to get the cutting point i must simulate till the 10kHz to 10 mHz
also i found that GB for TL082 under typical conditions is 3 mHz from its datasheet
when...
Hi lhlbluesky,
I got the simulation done in b2spice. i constructed the circuit with TL081 (which is 100% similar in specs to TL082)
yes the circuit is a Non Inverting Differentiator. the B2Spice had test called 'AC Sweep' in which i set the frequency in range of 1 kHz to 1 mHz and i got...
Thanks for the above Solution 1 it helped a lot.
I have this one more problem.
i need to find the Gain Bandwidth Product from the magnitude and/or frequency plots . i really dont understand how.
this plot i got from the simulation of the above circuit with B2spice .
please help me how can i...
