GENERAL DESCRIPTION
The ADG201A-EP is a monolithic CMOS device comprising
four independently selectable switches. They are designed on an
enhanced LC
2
MOS process, which gives an increased signal
handling capability of ±15 V. These switches also feature high
switching speeds and low R
ON
.
The ADG201A-EP exhibits break before make switching action.
Inherent in the design is low charge injection for minimum
transients when switching the digital inputs.
Full details about this enhanced product are available in the
ADG201A data sheet, which should be consulted in conjunc-
tion with this data sheet.
PRODUCT HIGHLIGHTS
1. Extended signal range of ±15 V.
2. Operates with 15 V single supply voltages.
3. Low leakage: 500 pA.
