Procurement Notes

Verify the specific suffix of the ordered part number against the manufacturer's current product status. The base model ADG919BRM may be listed as obsolete or discontinued in some distributor catalogs, while variants like ADG919BRMZ remain active. Confirm availability through official Analog Devices channels or authorized distributors to ensure component authenticity and lifecycle compliance before finalizing procurement plans.

Selection Notes

Select this component when a reflective SPDT switch is required for signals up to 4 GHz with low insertion loss. Ensure the system design accommodates the 1.65 V to 2.75 V supply voltage range. Consider the 8-MSOP package dimensions for PCB layout constraints. Verify that the 37 dB isolation at 1 GHz meets the system's interference requirements, noting that isolation characteristics vary with frequency.

Part Context

The ADG919BRM belongs to the ADG91x series of wideband CMOS switches from Analog Devices. This family includes related parts such as the ADG918 and ADG919, which share similar architectural features but differ in termination specifications and performance metrics. These components are designed for high-frequency applications where low power and compact size are critical.

Replacement Considerations

The ADG919BRMZ is a direct replacement variant available from Analog Devices. Verify pin compatibility and electrical parameter equivalence before substitution. Other members of the ADG91x family may serve as functional alternatives depending on specific isolation and frequency requirements.
