What power-supply considerations affect the precision of the ADA4177?

The ADA4177 is designed to be robust when powered from a variety of power supplies. With an excellent power-supply rejection ration (PSRR) of 145dB, it can tolerate significant supply noise. When calculating the total precision of a signal path, be sure to look at the noise from the power supply and its contribution after being attenuated by the ADA4177’s power supply rejection.
