Nov 20, 2006  
The DG441 and DG442 monolithic CMOS analog switches  
are drop-in replacements for the popular DG201A and  
DG202 series devices. They include four independent single  
pole single throw (SPST) analog switches, TTL and CMOS  
compatible digital inputs, and a voltage reference for logic  
thresholds.

• Low Charge Injection  
DG201A and DG202. Charge injection has been reduced,  
simplifying sample and hold applications.  
• Upgrade from DG201A, DG202  
• TTL, CMOS Compatible  
The improvements in the DG441 series are made possible  
by using a high voltage silicon-gate process. An epitaxial  
layer prevents the latch-up associated with older CMOS  
technologies. The 44V maximum voltage range permits

signals. Power supplies may be single

Applications  
ended from +5V to +34V, symmetrical supplies from ±5V to  
±22V or asymmetrical supplies limited to a maximum  
differential voltage of 44V with a V+ max of 34V or a V- max  
of -25V.  
• Audio Switching  
• Battery Operated Systems  
• Data Acquisition  
The four switches are bilateral, equally matched for AC or  
bidirectional signals. The ON resistance variation with  
analog signals is quite low over a 5V analog input range.  
The switches in the DG441 and DG442 are identical,  
differing only in the polarity of the selection logic.
