ADG936BRU

Overview

The ADG936BRU is a wideband analog switch featuring two independently selectable single-pole double-throw (SPDT) circuits fabricated using CMOS technology. It provides high isolation and low insertion loss up to 4 GHz, with typical off-isolation of 36 dB at 1 GHz and insertion loss of 0.9 dB from DC to 1 GHz. The device operates on a single 1.65 V to 2.75 V power supply and supports CMOS/LVTTL control logic. It is housed in a 20-lead TSSOP package and consumes a maximum power of 1 µA.

Feature Summary

• Absorptive dual SPDT topology with 50 Ω terminated shunt legs for matched performance
• Wideband operation supporting frequencies up to 4 GHz with high off-isolation
• Low power consumption with maximum current draw of 1 µA
• Compatible with standard CMOS and LVTTL control logic levels

Applications

• Wireless communications systems
• General-purpose RF switching
• Dual-band applications
• High-speed filter selection
• Antenna diversity switching

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm package type and tape/reel specifications. Ensure the component matches the required absorptive topology rather than reflective variants. Confirm RoHS compliance status and lead-free markings on the physical device prior to integration into production assemblies.

Selection Notes

Select this component when an absorptive switch architecture is required to maintain impedance matching in signal paths. The dual SPDT configuration allows independent control of two channels within a compact footprint. Consider the 4 GHz bandwidth and low insertion loss characteristics for high-frequency signal routing applications requiring minimal signal degradation.

Part Context

The ADG936BRU belongs to the ADG936 family of wideband analog switches manufactured by Analog Devices. This series utilizes CMOS processes to deliver high isolation and low insertion loss. The BRU designation specifically indicates the 20-lead TSSOP surface-mount package variant within the broader product line that includes reflective versions and different packaging options.

Replacement Considerations

The ADG936BRUZ serves as a lead-free replacement variant within the same package form factor. For reflective topology requirements, the ADG936BRU-R is the functional counterpart. Verify pinout compatibility and electrical parameters before substituting with other dual SPDT RF switches.
