Hi,
In one circuit, it was found that the slew rate of the OPA was slow and affected the measurement accuracy. So when OPA2197 with a high slew rate was used, an improvement in accuracy was observed. However, the margin of the terminal input/output current is low, so I am looking for an OPA that matches the other conditions.
Conditions
- Number : 2ch
- Slew rate : 20 V/us
- input/output current: ±10mA or more
- Package: SOIC - 8pin
As far as I can find, the maximum input/output current of TI's SOIC packages is ±10 mA. This is probably due to the internal diode clamping. If you know of any products that can flow more than 10 mA, please let me know.
Thanks,
Conor
