-55C rated zero drift Opamps

Hi Kavindu,

Good day. You may want to look at AD8629 which is a Zero-Drift, Single-Supply, Rail-to-Rail Input/Output Operational Amplifier with a rated temperature range of -55C to 125C available on 8-pin MSOP and SOIC_N package. Also, you may also want to look at ADA4528-2-EP which is a Precision, Ultralow Noise, RRIO, Zero-Drift Dual Op Amp with a temperature range of -55C to 125C available on 8-pin MSOP and 8-lead LFCSP. Feel free to ask if you have other parameters in mind to consider in your selection. Thank you.

Hi Gilbeys,

Thank you very much for the information provided. One problem I'm seeing is the quiescent current because I'm working on a 2 -wire 4 - 20 mA design. Appreciate if you can suggest something similar yet with low power capability

Hi Kavindu,

Good day. You want to check ADA4528-2 which is available on the 8-lead LFCSP and MSOP package. Its Iq is typically around 1.4m and has an operating range of -55C to 125C.

But if you're looking for a 4-20 mA driver, you may want to look into our "Industrial 4-20 mA Driver catalog".

I hope this helps.
