ADG839YKSZ-500RL7

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG839YKSZ-500RL7 is a low voltage CMOS single-pole double-throw (SPDT) switch manufactured by Analog Devices Inc. It operates on a single supply ranging from 1.65 V to 3.6 V and features an ultralow on resistance of 0.35 Ω typical, with a maximum of 0.6 Ω across the automotive temperature range of –40°C to +125°C. The device supports rail-to-rail switching, high current carrying capability of 300 mA continuous, and excellent audio performance with total harmonic distortion plus noise as low as 0.01%. Packaged in a compact 6-lead SC-70 (KS-6) surface-mount format, it consumes less than 0.1 µW typically.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix matches the required packaging configuration. Confirm that the component meets RoHS compliance standards for lead-free manufacturing. Ensure the automotive temperature grade variant is selected if deployment requires operation within the specified extended thermal limits. Cross-reference the datasheet revision to confirm parameter stability before finalizing procurement specifications.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when designing circuits requiring a single SPDT switch with minimal signal loss in low voltage environments. Consider the 0.6 Ω maximum on resistance limit when calculating voltage drops for high-current applications. Verify that the digital input voltage levels align with the system's logic family, particularly for 1.8 V operation. Evaluate the package size constraints against available PCB real estate for the 6-lead SC-70 footprint.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the ADG839 series of low voltage analog switches. It shares functional similarities with other devices in the ADG8xx family but is distinct in its single-channel SPDT configuration. The Y suffix denotes the automotive temperature rating, differentiating it from commercial grade variants. The KSZ suffix indicates the specific 6-lead thin shrink small outline transistor package used for surface mount assembly.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct substitutes include the ADG839YKSZ-REEL or ADG839YKSZ-REEL7, which share identical electrical characteristics and pinouts but differ only in reel packaging quantities. Other members of the ADG8xx family may offer similar performance but require verification of channel count and on-resistance specifications to ensure compatibility.
