Features

1)The built-in bias resistors consist of thin-film resistors with complete

isolation to allow positive biasing of the input, and parasitic effects

are almost completely eliminated.

2)Only the on / off conditions need to be set for operation, making the

device design easy.

3)Higher mounting densities can be achieved.
