, temperature, and voltage. Worst-case signal path, audio or
USB channel, is characterized.
5. Flatness is defined as the difference between the maximum and minimum values of on resistance over the
specified range of conditions.
6. Guaranteed by characterization, not production tested.
7. On resistance is determined by the voltage drop between the A and B pins at the indicated current through the switch.
