Note 1: When the analog signal exceeds +13.5V or -13.5V, the blocking action of Maxim
’
s gate structure goes into operation. Only
leakage currents flow, and the channel on-resistance rises to infinity (see
Typical Operating Characteristics
).
Note 2: Electrical characteristics such as on-resistance will change when power supplies other than ±15V are used.
Note 3: ∆R

Note 4: Leakage parameters are 100% tested at maximum rated hot operating temperature, and guaranteed by correlation at +25°C.
Note 5: Guaranteed by design.
