The ADG221 and ADG222 are monolithic CMOS devices comprising four independently selectable switches. On-chip latches facilitate microprocessor interfacing. They are designed on an enhanced LC2MOS process which gives an increased signal handling capability of ±15 V. These switches also feature high switching speeds and low RON.
The ADG221 and ADG222 consist of four SPST switches. They differ only in that the digital control logic is inverted. All devices exhibit break before make switching action. Inherent in the design is low charge injection for minimum transients when switching the digital inputs.
At least one model within this product family is in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist.
