The ADG5243F comprises three independently selectable, singlepole/double-throw (SPDT) switches. All channels exhibit break-before-make switching action that prevents momentary shorting when switching channels. An EN input enables or disables the device. When disabled, all channels are switched off. Each switch conducts equally well in both directions when on, and each switch has an input signal range that extends to the supplies. The primary supply voltages define the on-resistance profile, whereas the secondary supply voltages define the voltage level at which the overvoltage protection engages.
When no power supplies are present, the channel remains in the off condition, and the switch inputs are high impedance. Under normal operating conditions, if the analog input signal levels on any Sx pin exceed the positive fault voltage (POSFV) or the negative fault voltage (NEGFV) by a threshold voltage (VT), the channel turns off and that Sx pin becomes high impedance. If the switch is selected to be on, then the drain pin is pulled to the secondary supply voltage that was exceeded. Input signal levels up to −55 V or +55 V relative to ground are blocked, in both the powered and unpowered conditions.
The low capacitance and charge injection of these switches make them ideal solutions for data acquisition and sample-andhold applications, where low glitch switching and fast settling times are required.
Note that, throughout this data sheet, multifunction pins, such as IN1/F1, are referred to either by the entire pin name or by a single function of the pin, for example, IN1, when only that function is relevant.
PRODUCT HIGHLIGHTS
- The source pins are protected against voltages greater than the secondary supply rails, up to −55 V and +55 V.
- The source pins are protected against voltages between −55 V and +55 V in an unpowered state.
- Overvoltage detection with the digital output indicates the operating state of the switches.
- Trench isolation guards against latch-up.
- Optimized for low charge injection and on-capacitance.
- The ADG5243F can be operated from a dual supply of ±5 V to ±22 V or a single power supply of 8 V to 44 V.
