OPA2210: Similar spec part, with higher slew rate

Hao Jie Chan

Part Number: OPA2210
Other Parts Discussed in Thread: OPA2211A, OPA2828, OPA2189

Hi TI,

I am looking at an application, in which OPA2210 can meet almost all requirements, except its slew rate. Do you have any part suggestions? I need ~3x OPA2210 slew rate, so it's ~20V/us.

The spec that makes OPA2210 stands out are:
-Offset drift of 0.5uV/degC max

-Noise density of 2.2nV/sqrtHz

-package of VSSOP (not a strict requirement, but the smaller the better)

-Operating voltage of 36V

Thanks

The OPA2211A is available in the WSON package.

But the drift is 3x worse than OPA2210, 1.5uV/degC max. The offset drift is quite important in my application so I would like to have a part that is lower in drift too.

In addition to OPA2211, you could also consider OPA2828 with slew rate of 150V/us. If offset and drift are also critical, OPA2189 chopper with max offset of +/-3uV and drift +/-0.02uV/C could also be a good choice.
