GENERAL DESCRIPTION
The ADG5233 and ADG5234 are monolithic industrial CMOS
analog switches comprising three independently selectable
single-pole, double throw (SPDT) switches and four indepen-
dently selectable SPDT switches, respectively.
All channels exhibit break-before-make switching action that
prevents momentary shorting when switching channels. An EN
input on the
(LFCSP and TSSOP packages) is used to
enable or disable the device. When disabled, all channels are
switched off.
The ultralow capacitance and charge injection of these switches
make them ideal solutions for data acquisition and sample-and-
hold applications, where low glitch and fast settling are required.
Fast switching speed coupled with high signal bandwidth make
these devices suitable for video signal switching.
PRODUCT HIGHLIGHTS
1.
Trench Isolation Guards Against Latch-Up.
A dielectric trench separates the P and N channel transistors
thereby preventing latch-up even under severe overvoltage
conditions.
2.
Ultralow Capacitance and 0.6 pC Charge Injection.
3.
Dual-Supply Operation.
For applications where the analog signal is bipolar, the
ADG5233/ADG5234 can be operated from dual supplies
up to ±22 V.
4.
Single-Supply Operation.
For applications where the analog signal is unipolar, the
ADG5233/ADG5234 can be operated from a single-rail
power supply up to 40 V.
5.
3 V Logic-Compatible Digital Inputs.
VINH = 2.0 V, VINL = 0.8 V.
6.
No VL Logic Power Supply Required.
