zFeatures
1) The built-in bias resistors consist of thin-film
resistors with complete isolation to allow negative
biasing of the input, and parasit ic effects are a lmost
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.
