AG201A Quad SPST Switch IC
The AG201A (or ADG201A) is a monolithic CMOS analog switch device that contains four independent Single-Pole Single-Throw (SPST) switches. Each switch is controlled digitally, and when activated it connects the analog signal path; when de-activated the path is open. It is intended for switching analog signals (or digital) with low on-resistance, low charge injection, and good signal-handling capability.
