Hello! I'm looking for AD chip that would be on the keys and management would like FST3125MX, but in the parameters better than ADG774BRQZ
That is, I'm looking for a chip AD, which would be 4 keys (no longer necessary). These keys must be controlled by separate signals. The resistance in the open state is less than 2 oHms. Low level control - the keys are open, a high level of control - the keys are closed. The switching frequency of the keys below 120Mhz.
