ADG453BRUZ

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG453BRUZ is a monolithic CMOS analog switch IC containing four independent single-pole/single-throw (SPST) switches. It features an on resistance of 5 Ω maximum and operates with supply voltages ranging from ±4.5 V to ±20 V for dual supplies, or 5.0 V to 13.2 V for single supplies. The device supports continuous currents up to 100 mA and offers switching times of 180 ns maximum for turn-on and 140 ns maximum for turn-off. It utilizes LC2MOS technology for ultralow power dissipation of 17.5 μW and includes break-before-make switching action. The component is housed in a 16-lead TSSOP package and functions within a temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and lead-free status. Confirm that the B version meets the required industrial temperature range specifications. Ensure compatibility with existing board layouts regarding the 16-lead TSSOP footprint before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the ADG453BRUZ when mixed logic control is required, as two switches use standard logic and two use inverted logic. This configuration supports break-before-make timing essential for multiplexing applications. Consider the 5 Ω on resistance and 100 mA current capability for load requirements. Verify supply voltage ranges match the application's single or dual rail constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

The ADG453BRUZ belongs to the ADG451/ADG452/ADG453 family of quad SPST switches fabricated on an enhanced LC2MOS process. It serves as a pin-compatible upgrade for older ADG411/ADG412/ADG413 and ADG431/ADG432/ADG433 series devices. The BRUZ suffix indicates a Pb-free variant in a 16-lead Thin Shrink Small Outline Package.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The ADG451BRUZ and ADG452BRUZ are pin-compatible alternatives within the same family. The ADG451 differs by having all switches controlled by non-inverted logic, while the ADG452 uses fully inverted logic. These parts share identical electrical characteristics but differ only in control logic polarity.

Analog Switches, Multiplexers, Demultiplexers FAQ

How does the ADG453 handle switching transitions in multiplexer applications?

The ADG453 exhibits break-before-make switching action, which prevents channel shorting when configured as a multiplexer.

What is the difference in digital control logic between the ADG453 and other family members?

The ADG453 has two switches with standard logic control and two switches with inverted logic control, whereas the ADG451 uses standard logic for all channels and the ADG452 uses inverted logic for all channels.

What is the maximum analog signal range supported by the ADG453BRUZ?

The analog signal range extends to the supplies, supporting up to ±15 V with dual supplies or unipolar signals up to the positive rail with single supplies.
