ADG413BR

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG413BR 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. The device supports single or dual supply operation, with maximum ratings of 44 V between supplies and ±15 V analog signal range. Key electrical parameters include a maximum on-resistance of 35 Ω, ultralow power dissipation of 35 μW, and fast switching times with tON < 175 ns and tOFF < 145 ns. It operates within an industrial temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific package variant (e.g., SOIC-16 or TSSOP-16) when ordering, as the base model number does not specify the footprint. Confirm RoHS compliance status if required for your assembly process. Check the manufacturer's current datasheet revision to ensure all specifications match your design requirements before finalizing procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the ADG413BR when mixed logic control is needed, as it combines non-inverted and inverted channels. Ensure the application voltage stays within the specified limits for both single and dual supply modes. Consider the break-before-make timing if using the device in multiplexer applications to avoid signal overlap. Verify thermal constraints based on the chosen package type.

Analog Switches, Multiplexers, Demultiplexers Part Context

The ADG413BR belongs to the ADG411/ADG412/ADG413 family of precision CMOS analog switches. While the ADG411 and ADG412 differ only by logic inversion across all channels, the ADG413 offers a hybrid configuration with two non-inverted and two inverted switches. This family serves as a plug-in replacement for older DG411/DG412/DG413 devices while offering improved performance characteristics.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The datasheet explicitly identifies the ADG411/ADG412/ADG413 series as a plug-in replacement for the legacy DG411, DG412, and DG413 models. When substituting these parts, verify that the pinout compatibility remains consistent with the original design, particularly regarding the logic control inputs and power supply pins.

Analog Switches, Multiplexers, Demultiplexers FAQ

How does the ADG413 differ from the ADG411 and ADG412?

The ADG413 features a mixed logic configuration where two switches have non-inverted logic and two have inverted logic. In contrast, the ADG411 has all switches with non-inverted logic, and the ADG412 has all switches with inverted logic.

What is the benefit of the break-before-make switching feature?

The break-before-make switching action ensures that one channel turns off before another turns on. This prevents channel shorting when the switches are configured as a multiplexer, protecting the circuit from signal overlap.

Can this device operate with a single power supply?

Yes, the ADG413 can operate from a single-rail power supply. It is fully specified with a single 12 V supply and remains functional with single supplies as low as 5 V, making it suitable for unipolar signal applications.
