ADG221KNZ

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG221KNZ is a CMOS analog switch manufactured by Analog Devices Inc., housed in a 16-pin plastic dual in-line package (DIP). It integrates four independent single-pole single-throw (SPST) switches. The device operates with a nominal supply voltage of ±15 V, supporting an operating temperature range from -40 °C to +85 °C. Key electrical specifications include a maximum on-resistance (Ron) of 145 Ω and a maximum turn-on time of 300 ns. The component is not RoHS compliant.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify RoHS compliance status prior to procurement as the component is listed as non-compliant. Confirm the specific suffix 'KNZ' matches the required lead finish and packaging configuration for your assembly process. Ensure the supplier provides official documentation verifying the manufacturer source and part authenticity to avoid counterfeit components.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when four independent SPST switching channels are required in a DIP package. Consider the 145 Ω maximum on-resistance and 300 ns switching speed against system requirements. Verify that the ±15 V supply capability aligns with the available power rails in the target design.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the ADG221 family of quad SPST analog switches. It shares functional similarities with other members like the ADG222KN but differs in specific pinout or performance characteristics. The 'KNZ' suffix typically denotes the specific package type and material composition defined by Analog Devices for this variant.
