High Voltage Latch-up Proof Quad SPDT Switches

The ADG5433 and ADG5434 are monolithic industrial CMOS analog switches comprising three independently selectable single-pole, double-throw (SPDT) switches and four independently selectable SPDT switches, respectively.

All channels exhibit break-before-make switching action that prevents momentary shorting when switching channels. An EN input on the ADG5433 (LFCSP and TSSOP packages) is used to enable or disable the device. When disabled, all channels are switched off.

The ultralow on resistance and on resistance flatness of these switches make them ideal solutions for data acquisition and gain switching applications, where low distortion is critical.

APPLICATIONS

* Relay replacement

* Automatic test equipment

* Data acquisition

* Instrumentation

* Avionics

* Audio and video switching

* Communication systems

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 ADG5433/ADG5434 can be operated from dual

supplies up to ±22 V.

* Single-supply operation. For applications where the analog

signal is bipolar, the ADG5433/ADG5434 can be operated from a

single-rail power supply up to 40V.

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

* No VL logic power supply required.

* Latch-up proof

* 8 kV HBM ESD rating

* Low on resistance (13.5 Ω)

* ±9 V to ±22 V dual supply operation
