Part Number: ADS2807 Hi,
1)On my ADS2807 evaluation board (and on my newly developed hardware) I noticed that REFTB = 2V and REFBB = 3V is this expected or could be a reason why I am getting undesired random output in the range of 400 to 3500 from the…
Part Number: ADS2807 Hello,
I wanted to stimulate an anti aliasing filter before ADS2807, Can I get a spice model for this ADC or is it fine if I stimulate the input to ADC as a 1.25M resistor in parallel with 3pF capacitor?
Can the transformer circuit…
Hello, I use a ADS2807 in my FPGA based analog & digital mixed system, but it doesn't work normally. I choose DC-Coupled ,Differential Driver circuit befor the AD input side just as the schematic shows. The chip's temperature rises to about 50° no matter…

Hi,
The curve are the ADS2807 Output.
the Analog input is related to function generator,
I use with the measurements a sine signal with 1 MHz of frequency
If I raise the signal more than 400 mV the…

hve a Problem with ADS2807 EVM. The Problem is with the Analog Input
J5, J6 , he d'ont Work. In Datasheet from ADS 2807 EVM there are
R5,R6,R7 und R8 not installed, but there are…
Other Parts Discussed in Thread: ADS2807 Hello, I use a high speed ADC ADS2807 in my anolog & digital system and I choose DC-Coupled Differential input mode as the image shows. According to my calculation, the Vin range is only -0.375~+0.375 in this circuit…
Couple of quick things Akash,
1. Where is your DC bias current path for the V+ inputs to the op amps?
2. This differential I/O op amp circuit sometimes has a common mode oscillation - probably not here, but we did see that in the OPA838 decomp device…
