Hello,
My customer will use AD9648( ADC )and ADL5562 (ADC driver) in their product.
And they want to add additional amp. (ADA4938-1) for compensating Gain value at the frond-end of ADL5562.
Q1) Would you advice your opinions about using 2 op amps at the front-end of AD9648 (Please refer below concept picture.)?
Q2) At the front-end of AD9648 (ADC), is the above concept usable circuit?
Q3) Can you recommend other components or circuits for this case?
( Amp with 5dB Gain + ADL5562 + AD9648)
1) Need additional 5dB Gain
2) Change single-ended signal to differential signals
3) Output signals should be met the input spec. of ADL5562.
Regards,
Se-woong
