Part details & applications

The ADG6404 is an analog 4:1 multiplexer. The ADG6404 switches one of four inputs to a common output, D, as determined by the 3-bit binary address line, A0, A1, and EN. For use in multiplexer applications, switches exhibit break-before-make switching action.

Each channel conducts equally well in both directions when on, and each switch has an input signal range that extends from VSS to VDD − 2 V. When switches are disabled, signal levels up to the supplies are blocked.

The digital inputs are compatible with 5 V, 3.3 V, and 1.8 V logic inputs without the requirement for a separate digital logic supply pin.

The on-resistance profile is exceptionally flat over the full-analog input range, which ensures good linearity and low distortion when switching audio signals.
