GENERAL DESCRIPTION
The ADG5236 is a monolithic CMOS device containing two
independently selectable single-pole/double throw (SPDT)
switches. An EN input on the LFCSP package enables or
disables the device. When disabled, all channels switch off. Each
switch conducts equally well in both directions when on and
has an input signal range that extends to the supplies. In the off
condition, signal levels up to the supplies are blocked. Both
switches exhibit break-before-make switching action for use in
multiplexer applications.
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 together with high signal bandwidth make
the device 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 <1 pC Charge Injection.
3. Dual-Supply Operation.
For applications where the analog signal is bipolar, the
ADG5236 can be operated from dual supplies up to ±22 V.
4. Single-Supply Operation.
For applications where the analog signal is unipolar, the
ADG5236 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.
