Hi,Emman and Joe,
Thank you for your explanations. I could not deal with the design for a little time.
Firstly;
I m making a chart for drivers and need ADS8130, AD9631, AD8331 and ADA4937 as well. Could you please provide their release date?
The application is baseband video sampling upto 25 MHz.
Actually we almost completed the circuit schematic with AD8138 but i think to update it after your comments. I will try to use ADA4930 since the newer one and recommanded for new designs. But i must not make any design error since there is limited time for complete project.
Originally, my application does not need AC coupling, but i m taking it into account in case we may need it. it just adds an capacitor and does not change any resistor values. So may be used in the circuit and can be used when needed.
I used Diff-Amp Calculator to get a circuit example both AD8138 and ADA4930 but i need to confirm it with you. So could you please create a circuit with Diff-Amp Calculator based on AD48138 and ADA4930 for following charecteristics:
- AD9215 will be used 2Vpp input level.
- AD9215 VREF will be driven by VOCM of driver if possible
-Original analog input voltage is 0-5V analog upto 25 MHz bw
-topology is the single ended to differential
i dont have any idea about input tracking.
-input must be terminated with 75 ohm
Best regards,
