1.6 On Resistance, ± 5 V, +12 V, and +3 V Quad SPST Switches
DESCRIPTION
The DG9424E, DG9425E, DG9426E are monolithic quad
single-pole-single-throw analog switches. The G9424E and
DG9425E differ only in that they respond to opposite logic
levels. The DG9426E has two normally open and two
normally closed switches. It can be given various
configurations, including four SPST, two SPDT, and one
DPDT.
Using BiCMOS wafer fabrication technology allows the
DG9424E, DG9425E, and DG9426E to operate on single
and dual supplies. Single supply voltage ranges from 3 V to
16 V while dual supply operation is recommended with
± 3 V to ± 8 V. Each switch conducts equally well in both
direction when on, and blocks input voltages up to the
supply levels when off.
The low and flat on resistance over the full input signal
voltage rang bring excellent linearity, reduce insertion loss
and signal distortion, make them ideal for data acquisition
and programmable gain control applications. These switch
characters also make them ideal fit for audio signal switch
and reed relay replacement.
The DG9424E, DG9425E, DG9426E feature low power
dissipation, fast switching speed, and low voltage logic
control threshold. Proprietary design enables the low charge
injection that minimize the switching transient.
Operation temperature is specified from -40 °C to +85 °C.
The DG9424E, DG9425E, DG9426E are available in 16 lead
TSSOP packages.
