Part Number: ADC3644 Hi team,
I use the ADC3644 with an external 1.6V reference. I attach the waveforms of each power supply and VREF. It will take some time for VREF to stabilize, but is there any problem as long as each power supply and VREF are stabilized…
Part Number: ADC3644 Other Parts Discussed in Thread: OPA837 , , REF3318 Hi team,
In the EVM of ADC3644, 1.6V of VREF is divided and supplied by REF3318 and OPA837. Is this because there was no 1.6V reference? If I use the ADC3644 with an external reference…
Part Number: ADC3644 Other Parts Discussed in Thread: ADC3664 , Dear Technical Support Team,
Do you have Comparison chart(pdf or ppt) for ADC3644(DDR CMOS or Serial CMOS) vs ADC3664(Serial LVDS).
I thought it was just the difference between DDR CMOS or Serial…
Part Number: ADC3644 Other Parts Discussed in Thread: ADC3643 , I'm wondering if the ADC3644 (and the ADC3643 if it different) is monotonic. The datasheets do not mention monotonic explicitly, but it puts the DNL at 0.5 typical and max of 0.97, which to…
Part Number: ADC3644 I'm having trouble understanding how the output bit mapper works. On page 38 of the ADC3644 data sheet, figure 8-37, gives you an example of the output mapping. The output on the right has an example cell of D0A (0x63, 0x54). I understand…
Part Number: ADC3644 Hello,
I am preparing to read and write to this ADC chip through the SPI interface. But I don't see anywhere in the datasheet (other than the eFuse) that says how long to wait between each command written to the bus. Does it matter…
Hi Taylor, the ADC3664 (14b, 2ch, 125MSPS, SLVDS) or ADC3644 (14b, 2ch, 125MSPS, CMOS) are higher speed grades of the ADC3643. The ADC3664EVM and ADC3644EVM have the option of using either the on-board THS4541 amplifier for DC-coupled or balun for AC-coupled…
Hi
I found ADC3644 can accept REF35160(REF=1.6V) directly.
Is it same for ADC3563?

Dear Nick,
Here i attached my simulation file. according to my design my input is from VGA and it is single ended. it is coming with a -40mv negative offset
i feeding it to differential amplifier.after that i am giving to…
