Notes:

4. On resistance is determined by the voltage drop between the A and B pins at the indicated current through the switch.

5. ∆ RON=RON max – RON min measured at identical VCC, temperature, and voltage. Worst-case signal path, audio, or

USB channel, is characterized.

6. Guaranteed by characterization, not production tested.

7. Flatness is defined as the difference between the maximum and minimum values of on resistance over the

specified range of conditions.
