ADG602BRMZ

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG602BRMZ is a monolithic CMOS single-pole single-throw (SPST) switch manufactured by Analog Devices Inc. It features a normally closed (NC) configuration with a maximum on-resistance of 3.3 Ω and an on-resistance flatness of less than 0.8 Ω. The device operates on dual supplies ranging from ±2.7 V to ±5.5 V or a single supply from +2.7 V to +5.5 V, supporting rail-to-rail input signal ranges. Key electrical parameters include a typical on-resistance of 2 Ω, maximum leakage currents of 1 nA, and switching times up to 155 ns for turn-on and 90 ns for turn-off under dual supply conditions. It offers 180 MHz bandwidth and low power consumption of 1 μA maximum.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix to confirm package type and packing quantity. The BRMZ suffix indicates an 8-lead MSOP tube package containing 50 units. Ensure compatibility with RoHS compliance standards if required by the manufacturing process. Confirm that the industrial temperature range of -40°C to +85°C meets the operational environment specifications before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the ADG602BRMZ when a normally closed analog switch is required for low-distortion signal paths. Compare its 3.3 Ω maximum on-resistance against other SPST switches to ensure it meets impedance matching requirements. Consider the 180 MHz bandwidth for high-frequency signal integrity. Verify that the single or dual supply voltage options align with the system's power architecture constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

The ADG602BRMZ belongs to the ADG601/ADG602 family of CMOS analog switches. While the ADG601 provides a normally open configuration, the ADG602 variant specifically offers a normally closed state. Both share identical electrical characteristics regarding resistance, speed, and power consumption, differing only in their default switch condition upon power-up or control input deactivation.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct functional replacements within the same family include the ADG601BRMZ for normally open applications. For different packaging, the ADG602BRTZ-REEL7 serves as a reel-based alternative in the SOT-23 form factor. Ensure substitute parts maintain the same NC configuration and electrical specifications to preserve circuit behavior without redesign.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the difference between the ADG601 and ADG602?

The primary difference is the switch configuration: the ADG601 is a normally open (NO) switch, while the ADG602 is a normally closed (NC) switch. All other electrical specifications remain identical.

Does the ADG602 support bidirectional signal flow?

Yes, the switch conducts equally well in both directions when turned on, allowing the Source and Drain terminals to function interchangeably as inputs or outputs.

What is the maximum continuous current rating?

The absolute maximum continuous current for either the Source or Drain terminal is 100 mA.
