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.

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.

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 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.
