GENERAL DESCRIPTION
The ADG5208F and ADG5209F are 8:1 and dual 4:1 analog
multiplexers. The ADG5208F switches one of eight inputs to a
common output, and the ADG5209F switches one of four
differential inputs to a common differential output. An EN input
on both devices enables or disables the device. Each channel
conducts equally well in both directions when on, and each
channel 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.
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 VDD or VSS by a threshold voltage (VT) the channel turns
off and the drain pin is pulled to the supply voltage that was
exceeded. 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 capacitance and charge injection of these switches make
them ideal solutions for data acquisition and sample-and-hold
applications, where low glitch switching and fast settling times
are required.
PRODUCT HIGHLIGHTS
1. The source pins are protected against voltages greater than
the supply rails, up to −55 V and +55 V.
2. The source pins are protected against voltages between
−55 V and +55 V in an unpowered state.
3. Trench isolation guards against latch-up.
4. Optimized for low charge injection and on capacitance.
5. The ADG5208F/ADG5209F can be operated from a dual
supply of ±5 V up to ±22 V or a single power supply of 8 V
up to 44 V.
