ADG842YKSZ-500RL7

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG842YKSZ-500RL7 is a single-pole, single-throw (SPST) CMOS analog switch from Analog Devices. It operates on a single supply voltage ranging from 1.65 V to 3.6 V and features an ultralow on resistance of less than 0.48 Ω across the automotive temperature range of –40°C to +125°C. The device supports rail-to-rail signal handling and offers high current carrying capability with 300 mA continuous and 500 mA peak ratings. Typical power consumption is below 0.01 µW. It provides excellent audio performance with total harmonic distortion plus noise as low as 0.02% and includes break-before-make switching action.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and reel specifications. Ensure compatibility with lead-free manufacturing processes if required by assembly standards. Confirm that the automotive grade temperature rating aligns with environmental design constraints for the target application.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when low on resistance and high current capacity are critical within a single-supply architecture. The ADG842 is appropriate for designs requiring the switch to be open during a logic high input state. Consider the SC70 package dimensions for space-constrained layouts and verify digital input voltage levels match the system logic family.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the ADG841/ADG842 series of low-voltage CMOS switches. While functionally similar to the ADG841, the ADG842 differs in its logic control behavior, remaining open for a logic high input. Both devices share identical electrical characteristics regarding on resistance, leakage, and power consumption.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The ADG841YKSZ-500RL7 serves as a functional substitute within the same series, differing only in the logic state required to close the switch. Verify pinout compatibility and ensure the alternative part meets the specific logic inversion requirements of the circuit design.
