Any suggestion for a beteer alternative for ADA4622-2
Have equal or better 1/f noise, bandwidth >5MHZ, slew rate, input impedance >10^9, high slew rate.
An alternative to ADA4622-2 could be the ADA4610-2 which has lower 1/f noise (0.45uApp), 16.3MHz GBWP, 25 V/us SR, 10^13 ohm input resistance. The "Vos TC" (offset drift) of ADA4610-2 (2uV/deg. C, B Grade) is better than ADA4622-2 (5uV/deg. C, B Grade).
However, ADA4610-2 input CM voltage range does not extend down to V- like ADA4622-2!
