Outputs are stable with capacitive loads of more than 1000 p F with no external pensation. The inputs of the ADA4177-1/ADA4177-2/ADA4177-4 feature outstanding precision amplifier robustness, providing input protection against signal excursions 32 V beyond either supply, as well as 70 d B of rejection for electromagnetic interference (EMI) at 1000 MHz.
