AD7768 driver

Question asked by splin on Jun 23, 2016

I want to drive 4 AD7768 channels with the same signal to improve the SNR when sampling at higher speeds. Is it possible to use a single driver op-amp without significantly compromising the ADC performance - especially noise and linearity, or is it necessary to use seperate drivers for each channel?

 

If I can use one driver, what would you recommend?

 

My signals (for the other 4 channels) are single ended, 0 to 5V; is it possible to perform the SE to differential conversion and the ADC driver with a single device (to save cost and board space), again without significantly compromising the overall performance? If so, what device would you recommend?
