The HI-524 is designed to operate into a wideband buffer amplifier such as the Intersil HA-2541. The multiplexer chip includes two "ON" switches in series, for use as a feedback element with the amplifier. This feedback resistance matches and tracks the channel ON resistance, to minimize the amplifier VOS and its variation with temperature. The HI-524 is well suited to the rapid switching of video and other wideband signals in telemetry, instrumentation, radar and video systems.
