... DACs and ADCs from Analog Devices. The ADG721, ADG722 and ADG723 contain two independent single-pole/single-throw (SPST) switches. The ADG721 and ADG722 differ only in that both switches are normally open and normally closed respectively. While in the ADG723, Switch 1 is normally open and Switch 2 is normally closed. ...

... ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although the ADG721/ADG722/ADG723 features proprietary ESD protection circuitry, per- manent damage may occur on devices subjected to high energy electrostatic discharges. There- fore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality ...

... Therefore, in order to maximize bandwidth a switch must have a low input and output capacitance and low on resistance. The On Response vs. Frequency plot for the ADG721/ADG722/ADG723 can be seen in Figure 7. Off Isolation Off isolation is a measure of the input signal coupled through an off switch to the switch output ...
