GENERAL DESCRIPTION PRODUCT HIGHLIGHTS The ADG211A and ADG212A are monolithic CMOS devices 1. Extended Signal Range. 2 comprising four independently selectable switches. They are These switches are fabricated on an enhanced LC MOS 2 designed on an enhanced LC MOS process, which gives an process, resulting in high breakdown and an increased increased signal handling capability of 15 V. These switches analog signal range of 15 V. also feature high switching speeds and low R . 2. Single Supply Operation. ON For applications where the analog signal is unipolar (0 V to The ADG211A and ADG212A consist of four SPST switches. 15 V), the switches can be operated from a single 15 V They differ only in that the digital control logic is inverted. In supply. multiplexer applications, all switches exhibit break-before-make 3. Low Leakage. switching action when driven simultaneously. Inherent in the Leakage currents in the range of 500 pA make these design is low charge injection for minimum transients when switches suitable for high precision circuits. The added switching the digital inputs. feature of break-before-make allows for multiple outputs to be tied together for multiplexer applications while keeping leakage errors to a minimum. Rev.
