ADG412BRZ-REEL

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG412BRZ-REEL is a precision quad SPST analog switch from Analog Devices, fabricated on an enhanced LC2MOS process. It features four independently selectable switches with TTL/CMOS-compatible logic requiring a high input to turn on. The device supports dual supplies up to ±16.5 V or a single supply of 12 V (functional down to 5 V). Key electrical parameters include a maximum on-resistance of 35 Ω at ±13.5 V supplies and 80 Ω typ at 12 V single supply. Switching times are tON < 175 ns and tOFF < 145 ns. It operates within the industrial temperature range of −40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Enhanced LC2MOS process provides ultralow power dissipation and extended signal range extending fully to supply rails.
• Break-before-make switching action prevents channel shorting in multiplexer configurations.
• Flat on-resistance profile over the full analog input range ensures excellent linearity and low distortion for audio signals.

Analog Switches, Multiplexers, Demultiplexers Applications

• Audio and video switching
• Automatic test equipment
• Precision data acquisition
• Battery-powered systems
• Sample-and-hold systems

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and RoHS compliance status. The BRZ designation indicates a lead-free SOIC package. Confirm that the reel quantity matches production requirements. Ensure the logic polarity (active high) aligns with the system control interface before finalizing procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the ADG412BRZ when active-high digital control logic is required, distinguishing it from the ADG411 which uses active-low logic. Verify that the 35 Ω maximum on-resistance meets the application's voltage drop constraints. Ensure the operating voltage stays within the specified limits for the desired RON performance. Consider the T-version if operation below −40°C is necessary.

Analog Switches, Multiplexers, Demultiplexers Part Context

The ADG412 is part of the ADG411/ADG412/ADG413 family of precision quad SPST switches. It serves as a plug-in replacement for legacy DG412 devices. The primary distinction within this group is the digital control logic: ADG411 is active-low, ADG412 is active-high, and ADG413 combines both polarities.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The ADG412 is explicitly documented as a plug-in replacement for the DG412. Verify pinout compatibility and logic polarity differences when substituting other quad SPST switches from different manufacturers.
