Will the ADA4177 drive an Analog-to-Digital Converter?

There are many considerations when driving an ADC.  A primary consideration is the noise and linearity of the amplifier driving the ADC. The effective resolution of an ADC is affected by its total harmonic distortion and noise (called “SINAD” in ADCs and “THD+N” in amplifiers). The driving amplifier must have a THD+N that is better than that of the ADC in order to maintain the resolution of the ADC. The ADA4177 has a THD+N of 0.002% or 94dB. This makes the ADA4177 suitable for processing signals into precision ADCs like the 16-bit AD7980 with its excellent SINAD of 91.5 dB.
