GENERAL DESCRIPTION
The ADG5436F is an analog multiplexer, containing two
independently selectable single-pole, double-throw (SPDT)
switches. An EN input is used to disable all the switches. For use
in multiplexer applications, both switches exhibit break-before-
make switching action.
resistance of the ADG5436F, combined with the on-resistance
flatness over a significant portion of the signal range, makes it
an ideal solution for data acquisition and gain switching
applications where excellent linearity and low distortion are
critical.
Each channel conducts equally well in both directions when on,
and each switch has an input signal range that extends to the
supplies. The digital inputs are compatible with 3 V logic inputs
over the full operating supply range.
Note that, throughout this data sheet, the dual function pin names
are referenced only by the relevant function where applicable. See
the Pin Configurations and Function Descriptions section for
full pin names and function descriptions.
When no power supplies are present, the switch remains in the off
condition, and the channel inputs are high impedance. Under
normal operating conditions, if the analog input signal level on
any Sxx pin exceeds VDD or VSS by a threshold voltage, VT, the
channel turns off and that Sxx pin becomes high impedance. If
the channel is on, the drain pin reacts according to the drain
response (DR) input pin. If the DR pin is left floating or pulled
high, the drain remains high impedance and floats. If the DR pin
is pulled low, the drain pulls to the exceeded rail. Input signal
levels of up to +55 V or −55 V relative to ground are blocked, in
both the powered and unpowered conditions. The low on
PRODUCT HIGHLIGHTS
1. Source pins are protected against voltages greater than the
supply rails, up to −55 V and +55 V.
2. Source pins are protected against voltages between −55 V
and +55 V in an unpowered state.
3. Overvoltage detection with digital output indicates the
operating state of the switches.
4. Trench isolation guards against latch-up.
5. Optimized for low on resistance and on-resistance flatness.
6. The ADG5436F operates from a dual supply of 5 V up to
22 V, or a single power supply of 8 V up to 44 V.
