High Voltage Latch-Up Proof, Quad SPST Switches

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 exhibits break-before-make switching action for use in multiplexer applications.

Product Highlights

* 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.

* Low RON.

* Dual-supply operation. For applications where the analog

signal is bipolar, the ADG5412/ADG5413 can be operated

from dual supplies up to ±22 V.

* 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.

* 3 V logic compatible digital inputs: VINH = 2.0 V, VINL = 0.8 V.

* No VL logic power supply required.
