PRODUCT HIGHLIGHTS

1. Extended Signal Range

The ADG417 is fabricated on an enhanced LC

giving an increased signal range that extends to the supply

rails.

2. Ultralow Power Dissipation

4. Single Supply Operation

For applications where the analog signal is unipolar, the

ADG417 can be operated from a single rail power supply.

The part is fully specified with a single +12 V power supply

and will remain functional with single supplies as low as

+5 V.

GENERAL DESCRIPTION

The ADG417 is a monolithic CMOS SPST switch. This switch

is designed on an enhanced LC

power dissipation yet gives high switching speed, low on resis-

tance and low leakage currents.

The on resistance profile of the ADG417 is very flat over the

full analog input range ensuring excellent linearity and low

distortion. The part also exhibits high switching speed and high

signal bandwidth. CMOS construction ensures ultralow power

dissipation making the parts ideally suited for portable and

battery powered instruments.

The ADG417 switch, which is turned ON with a logic low on

the control input, conducts equally well in both directions when

ON and has an input signal range that extends to the supplies.

In the OFF condition, signal levels up to the supplies are

blocked. The ADG417 exhibits break-before-make switching

action for use in multiplexer applications. Inherent in the design

is low charge injection for minimum transients when switching

the digital input.
