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.

PRODUCT HIGHLIGHTS  
1. Power-Off Protection On Both S and D Pins.  
2. PSS Robustness.  
GENERAL DESCRIPTION  
The ADG4612/ADG4613 contain four independent single-  
pole/single-throw (SPST) switches. The ADG4612 switches are  
turned on with Logic 1 on the appropriate control input. The  
ADG4613 has two switches with digital control logic similar to  
that of the ADG4612; the logic is inverted on the other two  
switches. Each switch conducts equally well in both directions  
when on, and each switch has an input signal range that extends  
to the supplies. The ADG4613 exhibits break-before-make  
switching action for use in multiplexer applications.  
3. Overvoltage Protection up to 16 V.  
4. 5.2 Ω On Resistance.  
5. 16-Lead TSSOP and 3 mm × 3 mm LFCSP Packages.  
When no power supplies are present, the switch remains in the  
off condition, and the switch inputs are high impedance inputs,  
ensuring that no current flows, which can damage the switch or  
downstream circuitry. This is very useful in applications where  
analog signals may be present at the switch inputs before power  
is applied or where the user has no control over the power supply  
sequence.  
In the off condition, signal levels up to 16 V are blocked. Also,  
when the analog input signal levels exceed VDD by VT, the switch  
turns off.
