GENERAL DESCRIPTION 

This data sheet describes the evaluation board for the ADG788, 
a triple SPDT switch packaged in a compact 4 mm × 4 mm body, 
20-lead LFCSP package. The switches are designed using an 
enhanced submicron CMOS process to provide optimal 
performance in terms of on resistance, bandwidth, and power 
dissipation. The excellent on resistance flatness makes the 
ADG788 ideal for a wide range of applications, including data 
and audio-video switching. Each SPDT switch can be 
individually controlled using a 1-wire parallel interface.  

The evaluation board supports both single- and dual-supply 
operation and comes fitted with connectors that allow the user 
to evaluate the performance of the ADG788 with minimum effort. 
The operation of the switches is controlled using the on-board 
links or by applying external control signals to the appropriate 
connectors. 

The data sheet for the ADG788 device is available from Analog 
Devices, Inc. It contains all the information regarding operation 
of the device, and it should be consulted in conjunction with 
this data sheet when using the evaluation board.
