GENERAL DESCRIPTION  
The ADG1608/ADG1609 are monolithic CMOS analog multip-  
lexers 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.  
The low on resistance of these switches make them ideal solu-  
tions 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.  
CMOS construction ensures ultralow power dissipation,  
making the parts ideally suited for portable and battery-  
powered instruments.  
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.  
PRODUCT HIGHLIGHTS  
1. 8 Ω maximum on resistance over temperature.  
2. Minimum distortion: THD + N = 0.04%  
3. 3 V logic-compatible digital inputs: VINH = 2.0 V, VINL = 0.8 V.  
4. No VL logic power supply required.  
5. Ultralow power dissipation: <8 nW.  
6. 16-lead TSSOP and 16-lead, 3 mm × 3 mm LFCSP.
