ADG431BNZ

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG431BNZ is a monolithic CMOS device comprising four independently selectable SPST analog switches. Fabricated on an enhanced LC2MOS process, it operates with single supplies from 5 V to 12 V or dual supplies up to ±16.5 V. Key electrical parameters include a maximum on-resistance of 24 Ω and ultralow power dissipation of 7.7 µW at ±16.5 V. Switching times are specified with a maximum tON of 165 ns and tOFF of 130 ns. The device features low leakage currents below 0.25 nA and TTL/CMOS compatible logic inputs.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Break-before-make switching action prevents channel shorting in multiplexer configurations.
• Flat on-resistance profile over the full analog input range ensures excellent linearity.
• Trench isolation technology provides latch-up proof performance.
• Rail-to-rail signal range extends fully to the supply rails.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix BNZ corresponds to the 16-lead Plastic DIP (N-16) package configuration. Confirm that the B version meets the required industrial temperature range specifications for -40°C to +85°C operation. Ensure compatibility with standard DIP footprint requirements during PCB layout planning.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when low charge injection and high switching speed are critical. The ADG431 requires a logic low input to turn the switch on, distinguishing it from the ADG432 which uses a logic high. Consider the ADG433 if mixed logic polarity control is needed within the same package. Verify supply voltage constraints against the flat on-resistance characteristics.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the ADG431/ADG432/ADG433 family of precision quad SPST switches. It serves as a direct plug-in replacement for older DG411/DG412/DG413 devices. The family utilizes enhanced LC2MOS technology to achieve superior power consumption and switching performance compared to standard CMOS processes.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Publicly confirmed substitute part numbers include ADG432BNZ and ADG433BNZ. These variants share identical pinouts and mechanical dimensions but differ in digital control logic inversion patterns. Verify logic level compatibility before substituting.
