REF5030 - Current Source 20uA

Other Parts Discussed in Thread: REF5030

Hi,

The idea is to use the REF5030 to make a precision current source of 20uA to use with a NTC.

Some data:

Vcc = 3.3V

Precision Current = 20uA.

Questions:

Can I use the REF5030 on this configuration? With GND connected to the OPA635 output?

The Bypass Cap, Trim Cap and Vout Cap are connected correctly?

Any considerations or advices?

Thank you.
