Description
The ADC02D2 is a 4 port switch with independent
DC voltage control on each port mounted in the
SOIC-8 package.
In transmit or receive applications, the asymmetric design
allows for good isolation between transmit and receive
path while maintaining medium power handling in
transmit port.
