GENERAL DESCRIPTION

The ADG5208F and ADG5209F are 8:1 and dual 4:1 analog multi-

plexers. 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.

The low capacitance and charge injection of these switches make

them ideal solutions for data acquisition and sample-and-hold ap-

plications, 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.

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

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

exceed positive fault voltage (V_DD) or negative fault voltage (V_SS

by a threshold voltage (V_T), the channel turns off and that Sx pin

)

becomes high impedance. If the fault channel is selected, the drain

pin is pulled to the secondary 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.

of ±5 V up to ±22 V or a single power supply of 8 V up to 44 V.
