Part Number: LMH6555 Tool/software: Hi, We are using LMH6555 op amp to convert a single ended 800mV signal to a differential signal to thereby drive an ADC. This is our circuit below, we have taken the values of resistors from the data sheet. We are giving…
Hello Wael,
I was able to recreate this, looks like whenever we try to import the model, the software overwrites this imported model with the incorrect model.
This is how we got around this issue while we wait on simulation team to update the fix:
…
Thanks for the reply. I need to drive ADC12QJ1600. Does this ADC12QJ1600 has inbuilt differential driver? or we should drive externally.
Can I use LMH6555 for converting the single ended to differential signal? for ADC12QJ1600 Could you please help me in…
Hi Reza,
Apologies for the late reply on this thread. In general you can use a rough rule of thumb of amplifier bandwidth that is 3 x (1/pulse width), which would be 3.3 GHz for your pulse. This is just a rough rule of thumb so you could use the LMH6555…
Other Parts Discussed in Thread: LMH6555 Dear Sir/Madam,
There are queries which need inputs from the company for the following part: LMH6555
1) What is the process technology used to fabricate the LMH6555, is it purely based on bipolar technology, CMOS,…
Other Parts Discussed in Thread: LMH6555 AN-1704 AKA SNOA500A, page 3, for the LMH6555, state that "The series and shunt resistances, Rx and Ry, present the proper cable termination (50ohm) and achieved the correct thevenin reistance (64.5) so that there…
Other Parts Discussed in Thread: LMH6555 Hi,
I will like to know the input and output swing of the LMH6555. Besides that, will you recommend me this to interface to a 12Bit ADC? If not, any recommendation on a fixed gain FDA?
Thanks.
Really not going to be able to answer this question without a min/max input offset spec on the LMH6552
Not sure where you got that 1mV typ number fromthe LMH6555, that fixed gain of about 5 device only quotes a min/max output of 50mV or about +/-10mV…
Part Number: ADC08B3000 Other Parts Discussed in Thread: LMH6555 , LMH6554 Hi,
My customer is using ADC08B3000. He wants to input Vin+/- single-end input signal.
The method of inputting single-end signal is showed Figure 46 in datasheet. But customer condition…
Other Parts Discussed in Thread: THS4513-SP , LMH6555 , THS4513 I am currently trying to replace a LMH6555 differential amplifier with a Rad hard part for a space mission. The THS4513-SP part says the minimum gain that it can have is 2V/V or 6dB but I am…
