ADG904BCPZ-REEL

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG904BCPZ-REEL is a wideband analog 4:1 multiplexer manufactured by Analog Devices Inc. It operates on a single 1.65 V to 2.75 V power supply and features CMOS/LVTTL control logic. The device provides a -3 dB frequency of 2.5 GHz, with an insertion loss ranging from 0.4 dB to 1.5 dB depending on frequency and voltage conditions. Off isolation reaches up to 60 dB at 100 MHz and 37 dB at 1 GHz. It utilizes a 20-lead Lead Frame Chip Scale Package (LFCSP) measuring 4 mm × 4 mm. The component supports an operating temperature range from -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm packaging format and reel specifications. Ensure the procurement channel sources components directly from authorized distributors or the manufacturer to guarantee authenticity and traceability. Confirm RoHS compliance status as indicated in the official datasheet before finalizing orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this model when an absorptive switch topology is required to minimize reflections back to the RF source. Compare performance metrics such as off-isolation and insertion loss against reflective variants like the ADG904-R if high off-port VSWR is not critical. Verify that the 20-lead LFCSP package dimensions fit the available PCB footprint and thermal management constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the ADG904 series of wideband SP4T switches. It shares functional similarities with the ADG904BRUZ but differs in physical packaging. The BCPZ variant specifically denotes the 20-lead LFCSP form factor. Other family members include reflective versions and automotive-grade alternatives designed for different environmental and reliability standards.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The ADG904BCPZ-REEL7 serves as a direct replacement regarding function and package type. For tape-and-reel configurations, verify the reel quantity specifications. The ADG904BRUZ offers identical electrical characteristics but requires a TSSOP footprint.
