Looking for OP AMP like ADA4622-2 but with lower temperature offset drift.

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.

Any suggestions?

Thanks

    Hi Zayouna,

    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!
