Note 2:
When the analog signal exceeds +13.5V or -12V, the blocking action of Maxim’s gate structure goes into operation. Only
leakage currents flow and the channel ON resistance rises to infinity.
Note 3:
The value shown is the steady-state value. The transient leakage is typically 50μA. See Detailed Description
Note 4:
Guaranteed by other static parameters.
Note 5:
Digital input leakage is primarily due to the clamp diodes. Typical leakage is less than 1nA at +25°C.
Note 6:
Leakage currents not tested at T
A
= cold temp.
Note 7:
Electrical characteristics, such as ON Resistance, will change when power supplies other than ±15V are used.
