ADG6436: 0.5 Ω R_ON, ±20 V, +36 V, Dual SPDT Switch

The ADG6436 is an analog multiplexer containing two independently selectable single-pole, double-throw (SPDT) switches. An EN input is used to disable all of the switches. For use in multiplexer applications, both switches exhibit break-before-make switching action.

Each channel in the ADG6436 conducts equally well in both directions when on, and each switch has an input signal range that extends from V_SS to V_DD − 2 V. When switches are disabled, the 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.
