Switch control pin. This logic input pin controls the SPST switch operation. For the OPA1S2384, a logic-low signal opens
the switch and a logic-high signal closes the switch. For the OPA1S2385, a logic-low signal closes the switch and a logic
high signal opens the switch.
Positive supply voltage pin. Connect this pin to a voltage +2.7V to +5.5V.
Negative supply voltage pin. Connect this pin to the ground (0 V) rail of the single-supply system power supply.
