ADG441BRZ-REEL

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG441BRZ-REEL is a monolithic CMOS device comprising four independently selectable SPST switches fabricated on an enhanced LC2MOS process. It operates with a maximum supply rating of 44 V and supports both single and dual power supplies. The component features low on-resistance (70 Ω max), low charge injection (6 pC max), and fast switching times (tON < 110 ns, tOFF < 60 ns). It utilizes trench isolation for latch-up protection and includes an internal voltage generator for logic power, eliminating the need for an external VL pin.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Enhanced LC2MOS process provides high switching speed and low power dissipation suitable for portable systems.
• Trench isolation technology ensures complete latch-up proof performance under severe overvoltage conditions.
• Internal voltage generator creates logic power supply, removing the requirement for an external VL pin connection.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix to confirm packaging format. The REEL suffix indicates tape and reel packaging, distinct from tube configurations. Confirm RoHS compliance status via the Z suffix if required by manufacturing standards. Ensure the B version temperature range matches the operational environment requirements.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this model when internal logic generation is preferred over external VL pin connections found in the ADG444 variant. Verify that the 70 Ω maximum on-resistance meets the circuit's linearity and distortion requirements. Ensure the 44 V absolute maximum rating accommodates the system's peak analog signal voltages without exceeding limits.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the ADG441/ADG442/ADG444 family of quad SPST switches. It serves as a plug-in replacement for legacy DG441 devices. The BRZ-REEL designation specifies the industrial temperature grade, SOIC-16 package, RoHS compliance, and reel packaging format.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Confirmed direct replacements include ADG441BR and ADG441ABR-REEL within the same series. These variants share identical electrical specifications and pinouts but may differ in packaging or lot traceability details.

Analog Switches, Multiplexers, Demultiplexers FAQ

Does the ADG441BRZ-REEL require an external logic power supply?

No, the ADG441 variant generates its own logic power supply internally using an on-chip voltage generator, unlike the ADG444 which requires an external 5 V supply on the VL pin.

What is the maximum analog signal range supported by this switch?

The analog signal range extends from VSS to VDD, allowing operation across the full supply voltage range up to the maximum 44 V rating.

How does the device prevent channel shorting in multiplexer configurations?

The device exhibits break-before-make switching action, which prevents channel shorting when multiple switches are configured as a multiplexer.
