ADG1212YRUZ-REEL

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG1212YRUZ-REEL is a quad single-pole/single-throw analog switch from Analog Devices, utilizing iCMOS technology for high-voltage operation. It supports a supply range of ±4.5 V to ±16.5 V (33 V total) with rail-to-rail signal handling. Key electrical parameters include a typical on-resistance of 120 Ω and maximum leakage currents of ±1 nA at extreme temperatures. The device features ultralow capacitance (1 pF off, 2.6 pF on) and charge injection below 1 pC. It operates with 3 V logic-compatible inputs without requiring a separate logic supply voltage.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current data sheet to confirm package type and reel specifications. The Y suffix indicates an extended industrial temperature range up to +125°C. Confirm RoHS compliance status as defined in the official documentation. Ensure the selected variant matches the required pin configuration and thermal characteristics for the target application environment.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the ADG1212 variant when non-inverted digital control logic is required, distinguishing it from the ADG1211. Consider the ADG1213 if break-before-make switching action is necessary for multiplexer configurations. Evaluate the TSSOP versus LFCSP package options based on available board space and thermal management requirements. Ensure the system voltage stays within the specified ±16.5 V maximum limit.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the ADG1211/ADG1212/ADG1213 family of low capacitance, low charge injection switches. These devices are designed for applications requiring high performance in a compact footprint. The family utilizes iCMOS technology to combine high voltage tolerance with low power consumption, making them suitable for portable and industrial instrumentation where signal integrity is critical.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The ADG1211YRUZ-REEL serves as a functional substitute with inverted logic control. The ADG1213YRUZ-REEL offers break-before-make switching for multiplexer use cases. Cross-reference the specific ordering suffixes to ensure identical packaging and temperature ratings. Verify that the replacement part maintains the same on-resistance and capacitance specifications for signal integrity compatibility.

Analog Switches, Multiplexers, Demultiplexers FAQ

How does the ADG1212 differ from the ADG1211?

The ADG1212 and ADG1211 have identical electrical specifications but differ in digital control logic polarity. The ADG1212 requires a Logic 1 input to turn the switch on, whereas the ADG1211 requires a Logic 0.

Is a separate logic supply voltage required?

No, the ADG1212 does not require a separate VL supply. The digital inputs are compatible with 3 V logic levels directly.

What is the maximum operating temperature for the Y version?

The Y version of the ADG1212 is rated for an extended industrial temperature range, with a maximum operating temperature of +125°C.
