ADG433BNZ

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG433BNZ is a precision quad single-pole single-throw analog switch from Analog Devices, fabricated on an enhanced LC2MOS process. It features four independently selectable switches with a maximum on-resistance of 24 ohms and ultralow power dissipation of 7.7 µW. The device supports dual supplies ranging from ±6.75 V to ±8.25 V (total 13.5 V to 16.5 V) or a single supply up to 13.2 V. Switching times are typically 90 ns for turn-on and 60 ns for turn-off. It includes break-before-make switching action and operates within an industrial temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix BNZ indicates a plastic DIP package when sourcing replacements. Confirm that the component meets RoHS compliance requirements if applicable to your assembly standards. Check for availability as distribution status may vary by region. Ensure the ordering part number matches the required logic configuration for the ADG433 variant.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the ADG433BNZ when mixed logic control is required, as it combines non-inverted and inverted inputs. Compare on-resistance specifications against system linearity requirements. Consider the ultralow leakage current for high-impedance signal paths. Verify that the operating voltage range aligns with the available single or dual supply rails in the target design.

Analog Switches, Multiplexers, Demultiplexers Part Context

The ADG433 is part of the ADG43x family of precision analog switches. It differs from the ADG431 and ADG432 by offering a mix of logic polarities: two switches operate with non-inverted logic while the other two use inverted logic. This allows flexible interfacing without external inverters. The family shares the same LC2MOS process technology for low power and high speed.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The datasheet identifies the DG411, DG412, and DG413 as plug-in replacements. When substituting, verify pin compatibility and ensure the replacement device supports the required signal range and switching speeds. Confirm that the alternative offers similar break-before-make timing characteristics to prevent multiplexer glitches.

Analog Switches, Multiplexers, Demultiplexers FAQ

How does the ADG433 differ from the ADG431 regarding control logic?

The ADG433 has two switches with digital control logic similar to the ADG431 (non-inverted), while the logic is inverted on the other two switches. The ADG431 has all four switches with non-inverted logic.

What is the purpose of the break-before-make switching action?

This feature prevents channel shorting when the switches are configured as a multiplexer by ensuring one switch turns off before another turns on.

Can the ADG433 operate with a single supply?

Yes, the device can operate from a single rail power supply. It is fully specified with a single 12 V supply and remains functional with supplies as low as 5 V.
