The ADG5404F is an analog multiplexer composed of four The low on resistance of the ADG5404F, combined with on- single channels with fault protected inputs. The ADG5404F resistance flatness over a significant portion of the signal range, switches one of the four inputs to a common drain, D, as makes it an ideal solution for data acquisition and gain determined by the 2-bit binary address lines (A0 and A1). An switching applications where excellent linearity and low enable digital input, EN, is used to disable all the switches. Each distortion are critical. channel conducts equally wel in both directions when on, and Note that, throughout this data sheet, the dual function pin names each switch has an input signal range that extends to the are referenced only by the relevant function where applicable.
