Marsh, I just talked with Rob about this so I will post on his behalf.
We are still unsure of the system design. For instance, in the above messages, you are mentioning inputs are from a power divider. Is this the analog input channels or the clock inputs…
Part Number: ADC3683 Due to clock distribution constrains in my design I would like utilize 20-bit output formatting in all modes: By-pass, real, complex (NCO is active). 1 wire connection is preferred. Acc. the datasheet is possible, but evaluation SW…
Part Number: ADC3683 Hello,
One customer used ADS3683 and wanted to configure the Decimation Bypass, 1-wire, 16bit mode, below is the configuration, but the FCLK duty cycle is not 50%.
I found the 0x20~x022 has no problem and 0x1B =0x88, I wonder why the…

Hi TI Expert,
I need to design a optical detector with wide dynamitc range so the input voltage to the AIN_P may be very large, for instance 3.4V.
And I notice that when the AIN_P is large and clamped by the the ADC's internel diode…
Part Number: ADC3683 Hi, When I enable test pattern and enable digital bypass, I can see the test pattern in my FPGA debugging environment. But with bypass disabled. There is no test pattern anymore, just raw ADC data (same with test pattern off and digital…
Part Number: ADC3683 Dear Sirs,
I am going to use this ADC with fully diff driver, coupling is DC. Its max output current is cca 30mA and supply voltage is 5V. Let assume I don't have implemented power sequencing. Do I have to protect analog inputs of…
Part Number: ADC3683 Other Parts Discussed in Thread: ADC3681 , ADC3682 , Hi,
the datasheet says that the input clock frequency works with a range of 0.5 to 65 MHz.
How is this correlated to the sampling rate of 65 MSPS?
Is it something like this:
ADC3681…
Part Number: ADC3683 Hi TI Expert,
I'd like to confirm something about the input range of the ADC3683.
When the Vcm=0.95 and I used the internal reference 1.6V.
In the datasheet, the differential input range is 3.2Vpp.
Then when I have AINP= 0…

Part Number: ADC3683 Other Parts Discussed in Thread: THS4551
Hi TI expert,
I find voltage attenuation on the input of ADC3683.
The single end intput voltage is 1.41V. But the ADC output is only around 1.28V.
The output of the FDA(THS4551) is correct…
