GENERAL DESCRIPTION
The ADG5212/ADG5213 contain four independent single-
pole/single-throw (SPST) switches. The ADG5212 switches
turn on with Logic 1. The ADG5213 has two switches with
digital control logic similar to that of the ADG5212; however,
the logic is inverted on the other two switches. Each switch
conducts equally well in both directions when on, and each
switch has an input signal range that extends to the supplies.
In the off condition, signal levels up to the supplies are blocked.
The ADG5212 and ADG5213 do not have a VL pin. The digital
inputs are compatible with 3 V logic inputs over the full
operating supply range.
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 parts 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
ADG5212/ADG5213 can be operated from dual supplies of
up to ±22 V.
4. Single-Supply Operation.
For applications where the analog signal is unipolar, the
ADG5212/ADG5213 can be operated from a single rail
power supply of 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.
