Rev 11.00
Nov 20, 2006 Monolithic CMOS Analog Switches
The DG401 and DG403 monolithic CMOS analog switches
have TTL and CMOS compatible digital inputs. Features These switches feature low analog ON resistance (<45пЃ—)
and fast switch time (tON<150ns). Low charge injection
simplifies sample and hold applications. Low Power Consumption (PD) .<35пЃW The improvements in the DG401, DG403 series are made
possible by using a high voltage silicon-gate process. An
epitaxial layer prevents the latch-up associated with older
CMOS technologies. The 44V maximum voltage range
permits controlling 30VP-P signals. Power supplies may be
single-ended from +5V to +34V, or split from п‚±5V to п‚±17V. ON Resistance (Max) . 45пЃ— Fast Switching Action

bidirectional signals. The ON resistance variation with analog
signals is quite low over a п‚±15V analog input range. The three
different devices provide the equivalent of two SPST (DG401)
or two SPDT (DG403) relay switch contacts with CMOS or
TTL level activation. The pinout is similar, permitting a
standard layout to be used, choosing the switch function as
needed. Applications Pinouts Hi-Rel Systems
