Low RON, Dual-SPDT/Single-DPDT Analog Switches with Slow Turn-On Time
General Description
The MAX4991–MAX4994 low on-resistance analog switches operate from a single +1.
8V to +5.
5V supply.
The MAX4991/MAX4993 feature a slow turn-on time to reduce clicks and pops due to coupling
capacitors and audio
amplifiers with a DC output bias.
This feature provides click-and-pop reduction without adding additional parts for existing architectures.
The MAX4991/MAX4992 are dual single-pole/doublethrow (SPDT) switches, while the MAX4993/MAX4994 are double-pole/double-throw (DPDT) switches.
The MAX4993/MAX4994 feature an active-low enable input (EN) that sets all t...
