GENERAL DESCRIPTION
The ADG211A and ADG212A are monolithic CMOS devices
comprising four independently selectable switches. 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 ADG211A and ADG212A consist of four SPST switches.
They differ only in that the digital control logic is inverted. In
multiplexer applications, all switches exhibit break-before-make
switching action when driven simultaneously. Inherent in the
design is low charge injection for minimum transients when
switching the digital inputs.
PRODUCT HIGHLIGHTS
1.
Extended Signal Range.
These switches are fabricated on an enhanced LC2MOS
process, resulting in high breakdown and an increased
analog signal range of ±15 V.
2.
Single Supply Operation.
For applications where the analog signal is unipolar (0 V to
15 V), the switches can be operated from a single 15 V
supply.
3.
Low Leakage.
Leakage currents in the range of 500 pA make these
switches suitable for high precision circuits. The added
feature of break-before-make allows for multiple outputs
to be tied together for multiplexer applications while
keeping leakage errors to a minimum.
