ADG1634LYCPZ-REEL7

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG1634LYCPZ-REEL7 is a monolithic industrial CMOS (iCMOS) analog switch comprising four independently selectable single-pole, double-throw (SPDT) switches. It features ultralow on resistance and flatness for low distortion in data acquisition and gain switching applications. The device supports ±3.3 V to ±8 V dual-supply or 3.3 V to 16 V single-supply operation with an external VL supply for 1.2 V and 1.8 V JEDEC logic compliance. It operates from -40°C to +125°C in a 24-lead, 4 mm × 4 mm LFCSP package.

Analog Switches, Multiplexers, Demultiplexers FAQ

How does the ADG1634L handle floating digital inputs?

The switches are guaranteed to be in the off state when the INx pins are floating, which prevents unwanted signal passage without requiring external pull-down resistors.

What is the purpose of the VL supply pin?

The VL supply provides flexibility for lower logic control levels, allowing the device to comply with both 1.2 V and 1.8 V JEDEC standards depending on the applied voltage.

Does the ADG1634L support rail-to-rail operation?

Yes, the device supports rail-to-rail operation across its specified single and dual supply voltage ranges.
