Let me try by doing modification as you said and I will update here. Sir I am also not clear about offset circuit and ripples.
Sir am attaching the complete schematic, PCB and other files with. Software used, Orcad 16.
Note:
R12 = R13 = 400 Ohm
R9 = R11 = 1K Ohm
R10 Removed
R1 = R2 = R3 = OR
@KlausST & @FvM ... Sorry Let me update now,, R10 is DNS here.
Sir R4 is the actually RM as per LMH6553 datasheet, at page 21, it says for 0db gain set RM to 26.7R (PowerPad IC).
Sir Tomorrow I will upload the updated schematic with layout files for Orcad.
I am working on HMCAD1520, for this I have to create a two stage input circuit, which translates 0v to 5v signal to -1v to +1v.
For this I created a circuit (PDF attached in the end) with AD8056 for -1 offset (adjustable with +/- 200mV), AD8009 for amplitude mapping (0v <-> 5v signal to 0v <->...
Hi experts,
I am going to use HMCAD1520 ADC and LMH6553 IC. I want to clear my mind about its maximum input voltage.
HMCAD1520 said at page 0-2 that, FSR Differential input voltage full scale range is 2 Vpp and Vcm is 0.9v. So what does 2Vpp is in differential mode.
P and N will swing from...
Yes I read and I will try it in my circuit by replacing ADG1408. Yet that IC is not available in my office store room. I have to order it.
I am placing order in DIGIKEY = ADG1604BCPZ-REEL7CT-ND. Will update the post and mark the answer after testing it if nothing goes wrong.
ok guys I got your answer. MUX will not do my job, so whats the alternative to my circuit or what I have to do on output side to stable my voltage level as well as current. I can allow voltage drop of 500mV.
As I said that ADG shows -7 volts but the current shows limit. I want to add that I...
Hi Experts,
Need your help for a circuit.
I made a circuit with CD4520 IC, the required output voltage is -8 volts but when load is attached to the circuit the voltage drops to approximately -3 volts (-2.286 Volts). So I found that ON resistance is 125 ohm so it is casing the voltage level drop...
Thanks for your great suggestions. I am only making it for washroom, so I don't think that counting the people going inside or outside is important. Also I am taking your suggestion about timer to turn off the light, but what happens if someone take long time in washroom but the light goes off...
Hi every body.
I am trying to create automatic light control circuit for washroom. I made some thing and want to share with experts. Please check the circuit and tell me if I am missing or using anything extra in the circuit.
Let me explain my circuit and problem;
I place magnet on the door...
