ADG1422BCPZ-REEL7

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG1422BCPZ-REEL7 is a dual single-pole/single-throw (SPST) analog switch manufactured by Analog Devices Inc. It utilizes iCMOS technology to support supply voltages up to ±15 V or +12 V while maintaining low power consumption. The device features a maximum on resistance of 2.4 Ω at 25°C and operates with 3 V logic-compatible inputs without requiring a separate logic supply voltage. It is housed in a 10-lead, 3 mm × 3 mm Lead Frame Chip Scale Package (LFCSP). The component supports an industrial operating temperature range from -40°C to +125°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Dual SPST switches with inverted digital control logic for turn-on activation.
• iCMOS construction enabling high voltage operation with ultralow power dissipation.
• Rail-to-rail signal handling capability extending to the supply rails.
• Flat on resistance profile ensuring excellent linearity and minimal distortion.

Analog Switches, Multiplexers, Demultiplexers Applications

• Automatic test equipment
• Data acquisition systems
• Relay replacements
• Battery-powered systems
• Audio and video signal routing

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific package variant against the datasheet ordering guide. The suffix REEL7 indicates tape and reel packaging. Confirm RoHS compliance status as indicated by the Z suffix in the base part number. Ensure the design accommodates the exposed pad connection requirements for the LFCSP thermal management.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when inverted logic control is required compared to the ADG1421. Verify that the maximum on resistance of 2.4 Ω meets the system's voltage drop requirements. Consider the 10-lead LFCSP footprint constraints during PCB layout. Ensure the application does not require break-before-make switching, which is a feature of the ADG1423 variant.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the ADG142x family of iCMOS analog switches. It shares the same physical package and core specifications as the ADG1421 and ADG1423. The primary distinction lies in the digital input logic polarity; the ADG1422 activates when the input is Logic 0, whereas the ADG1421 activates with Logic 1.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The ADG1421BRMZ-REEL7 serves as a direct functional substitute if non-inverted logic control is acceptable. The ADG1423BCPZ-REEL7 is suitable if break-before-make switching action is required for multiplexer configurations. Both alternatives share the same LFCSP-10 package and electrical characteristics.
