ADG1609 S1A DA S4A S1B DB S4B 1-OF-4 DECODER 08318-001 08318-002 GENERAL DESCRIPTION The ADG1608/ADG1609 are monolithic CMOS analog multiplexers comprising eight single channels and four differential channels, respectively.
The ADG1608 switches one of eight inputs to a common output, as determined by the 3-bit binary address lines, A0, A1, and A2.
The ADG1609 switches one of four differential inputs to a common differential output, as determined by the 2-bit binary address lines, A0 and A1.
An EN input on both devices is used to enable or disable the device.
When disabled, all channels are switched off.
Each switch 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.
All switches exhibit break-before-make switching action.
Inherent in the design is low charge injection for minimum transients when switching the digital inputs.

The low on resistance of these switches make them ideal solutions for data acquisition and gain switching applications where low on resistance and distortion is critical.
The on-resistance profile is very flat over the full analog input range, ensuring excellent linearity and low distortion when switching audio signals.
