GENERAL DESCRIPTION
The ADG5412/ADG5413 contain four independent single-
pole/single-throw (SPST) switches. The ADG5412 switches
turn on with Logic 1. The ADG5413 has two switches with
digital control logic similar to that of the ADG5412; 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 ADG5412 and ADG5413 do not have a VL pin. The digital
inputs are compatible with 3 V logic inputs over the full
operating supply range.
The on-resistance profile is very flat over the full analog input
range, which ensures good linearity and low distortion when
switching audio signals. High switching speed also makes the
devices suitable for video signal switching. The ADG5413

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. Low RON.
3. Dual-supply operation. For applications where the analog
signal is bipolar, the ADG5412/ADG5413 can be operated
from dual supplies up to ±22 V.
4. Single-supply operation. For applications where the analog
signal is unipolar, the ADG5412/ADG5413 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.
