AD7626 signal chain for higher frequency measurements >1MHz

The AD7626 datasheet does show AC dynamic performance with input frequencies up to 2.4MHz. In addition there is a Circuit Note CN0105 that shows the AD7626 10 MSPS 16 bit ADC used with the ADA4932-1 Fully Differential Amp doing Single ended to differential conversion in addition to driving the AD7626 input. This Circuit note shows performance with a tone of 2.4MHz the SINAD is >84.5 dB. Also use the Precision ADC Driver tool to test the AD7626 with different ADC driver options at higher input frequency tones to understand the best option for your design.
