ADC3908D125: Simulation Process

TI-CSC
Genius 15200 points

Part Number: ADC3908D125

Hello E2E Experts,

We are feeding a 250mV signal into the inverting input of the AD8002. The single-ended output (Gain=1) from the AD8002 is then connected to the non-inverting input of the AD8138. The differential outputs with swing (1.9Vp-p) from the AD8138 are fed into the ADC3908D125, and the 8-bit outputs from the ADC are sent to the FPGA.
 
as we did simulation for cascaded AD8002 & AD8138 and got the differential swing approximately 1.9Vp-p, Could you please give us the guidance to simulate ADC3908D125.

    HI,

    Unfortunately, there are no models available for simulation of any high-speed ADC.

    if you are confident your input fullscale of 1.9V thru simulation, then its either time to design your board or purchase the ADC39xxEVM from TI can verify a mock up design on your lab bench.

    From there, you can verify the performance using our HW and SW tools.

    Regards,
