Low Voltage, Dual Supply, Low R
ON
, Quad SPST Analog Switches
DESCRIPTION
The DG9424, DG9425, DG9426 are low voltage precision
monolithic quad single-pole-single-throw analog switches.
Using BiCMOS wafer fabrication technology allows the
DG9424, DG9425, DG9426 to operate on single and dual
supplies. Single supply voltage ranges from 3 V to 12 V while
dual supply operation is recommended with ± 3 V to ± 6 V.
Combining high speed (t
ON
: 42 ns), flat R
DS(on)
over
the analog signal range (), minimal insertion lose (-3 dB at
190 MHz), and excellent crosstalk and off-isolation
performance, the DG9424, DG9425, DG9426 are ideally
suited for audio and video signal switching.
The DG9424 and DG9425 respond to opposite control logic
as shown in the truth table. The DG9426 has two normally
open and two normally closed switches.
