ADG412BNZ

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG412BNZ 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 analog signal ranges up to ±15 V. The component features a typical on resistance of 25 Ω and a maximum of 35 Ω at +25°C. Switching times are specified as tON < 175 ns and tOFF < 145 ns. It exhibits ultralow power dissipation of 35 μW and low charge injection of 5 pC. The device is housed in a 16-lead Plastic Dual In-Line (PDIP) package and functions within an industrial temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Enhanced LC2MOS process provides extended signal range extending fully to the supply rails.
• Break-before-make switching action prevents channel shorting in multiplexer configurations.
• TTL- and CMOS-compatible digital control logic requires a logic high to turn switches on.
• Ultralow power dissipation makes the device suitable for battery-powered instruments.

Analog Switches, Multiplexers, Demultiplexers Applications

• Audio and video signal switching
• Automatic test equipment
• Precision data acquisition systems
• Sample-and-hold circuits

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix 'BNZ' corresponds to the 16-lead PDIP package and RoHS compliance status. Confirm that the B version meets the required -40°C to +85°C industrial temperature range specifications. Ensure the logic polarity matches the design requirements, as the ADG412 uses inverted control logic compared to the ADG411.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the ADG412BNZ when a non-inverted digital control logic is required, distinguishing it from the ADG411 which uses inverted logic. Consider the 35 Ω maximum on resistance and 175 ns switching speed for signal integrity requirements. Verify that the single-supply operation down to 5 V or dual-supply configuration aligns with the system power architecture.

Analog Switches, Multiplexers, Demultiplexers Part Context

The ADG412BNZ belongs to the ADG411/ADG412/ADG413 family of precision quad SPST switches. While electrically similar to the ADG411, the ADG412 differs specifically in its digital control logic polarity. It serves as a plug-in replacement for legacy DG412 devices, maintaining compatibility while offering improved performance through the LC2MOS fabrication process.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The ADG412BNZ is explicitly documented as a plug-in replacement for the DG412. Designers should verify pinout compatibility and ensure that the logic level requirements match the existing control circuitry when substituting legacy components.
