I'm interested in making the following resistor-divider circuit where I can tell 'POLL' to be high by my Arduino and then sample the voltage reading. The battery will have anywhere from 6-10volts. I have quite a few 2N2222A's on hand and I was wondering if I could use it as Q1 as the voltage specification says 40v 500mA (I don't expect a load to be on this), similarly, I was wondering if I could use J176 as M1 or if there are other options? Due to size constraints I'm trying to use all TO-92 packages.
This device is designed for low level analog switching sample and hold circuits and chopper stabilized amplifiers.
