ADG1434YRUZ

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG1434YRUZ is a monolithic industrial iCMOS analog switch featuring four independently selectable single-pole, double-throw (SPDT) channels in a 20-lead TSSOP package. It operates with supply voltages ranging from ±4.5 V to ±16.5 V or a single 5 V to 16.5 V source. The device exhibits a maximum on-resistance of 4.7 Ω at 25°C and maintains an on-resistance flatness of 0.5 Ω. Key dynamic specifications include a transition time of up to 170 ns, off-isolation of -70 dB at 1 MHz, and a -3 dB bandwidth of 200 MHz. It supports continuous channel currents up to 100 mA and features 3 V logic-compatible inputs.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging format and temperature grade. Confirm that the Y suffix corresponds to the industrial temperature range of -40°C to +125°C as defined in the manufacturer's ordering guide. Ensure compatibility with the required 20-lead TSSOP footprint and pinout configuration before integration into the design.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when four independent SPDT switching paths are required within a compact surface-mount footprint. The device is suitable for applications demanding rail-to-rail signal swing and low distortion. Verify that the system supply voltage falls within the specified 5 V to 16.5 V range and that the logic interface meets the 3 V compatibility requirements.

Analog Switches, Multiplexers, Demultiplexers Part Context

The ADG1434YRUZ belongs to the ADG1433/ADG1434 family of iCMOS switches manufactured by Analog Devices Inc. This series utilizes a specialized process combining high-voltage CMOS and bipolar technologies to achieve performance levels unattainable with conventional CMOS processes. The YRUZ designation specifically identifies the industrial temperature variant housed in a 20-lead Thin Shrink Small Outline Package.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The ADG1433 serves as a functional substitute offering three SPDT channels in a 16-lead TSSOP package. Both devices share identical electrical characteristics, iCMOS construction, and pinout configurations for their respective channel counts. Designers must account for the difference in package size and available I/O pins when transitioning between these models.

Analog Switches, Multiplexers, Demultiplexers FAQ

Does the ADG1434YRUZ feature an enable pin?

Yes, the ADG1434YRUZ includes an active-low digital input (EN) that disables all switches when driven high.

What is the maximum operating supply voltage for this device?

The device supports dual supplies up to ±16.5 V or a single supply up to 16.5 V.

How does the device handle channel switching to avoid signal glitches?

It employs a break-before-make switching action, which ensures that one channel disconnects before the next connects, preventing momentary shorting.
