#172058 - Should not be important Responding to: ???'s previous message |
Rdon is the dynamic resistance measured with Vgs=0 and near the Vds=0 point. It should be important if you use the J309 as analog switch, but not too much as amplifier.
How is your circuit? Frequency? Expected gain? Also, put devices in parallel will not help for GAIN. Daniel |
