Applications Information  
All DG300 family switches will operate with 5V to 15V  
power supplies. They can also be used with single-ended  
power supplies ranging from +10V to +30V where the V-  
terminal is connected to ground. In either case, analog  
signals ranging from V+ to V- can be switched.

voltage is shown in the Typical Operating Characteristics.  
The temperature coefficient of R  
is typically 0.5%/°C.

The charge injection test circuit is shown in Figure 1.  
Table 2 lists the typical injected charge for DG300 series  
switches with various input voltages.  
Typical on-resistance matching from channel to chan-  
nel is 10%. In addition, Table 1 outlines some typical  
parameters for single-supply operation.
