ADG741BKS-REEL

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG741BKS-REEL is a single-pole single-throw (SPST) CMOS analog switch manufactured by Analog Devices Inc. It operates on a single supply voltage ranging from 1.8 V to 5.5 V and features a typical on resistance of 2 Ω with low flatness. The device provides a -3 dB bandwidth exceeding 200 MHz, fast switching times with tON at 18 ns maximum and tOFF at 12 ns maximum, and extremely low power consumption with a maximum supply current of 1 µA. It is housed in a compact 6-lead SC-70 package and supports an industrial operating temperature range from -40°C to +85°C.

• Signal routing in data acquisition systems.
• Communication equipment requiring fast switching speeds.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix to confirm the reel quantity and lead-free status. The base part number indicates the functional specification, while suffixes like REEL or REEL7 denote packaging variations. Ensure the component matches the required industrial temperature grade and package option KS-6 for the 6-lead SC-70 configuration before procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a single-channel SPST switch is required with low on resistance and high bandwidth. Consider the supply voltage constraints, as on resistance increases significantly at lower voltages such as 1.8 V. Evaluate the package size requirements against the available 6-lead and 5-lead SC-70 options to ensure compatibility with the PCB layout.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the ADG741/ADG742 family of CMOS low-voltage switches. The ADG741 variant specifically provides a single SPST channel, whereas the ADG742 offers dual channels. Both share similar electrical characteristics but differ in pin configurations and channel counts within the same SC-70 package family.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct replacements include other parts from the ADG741/ADG742 series with compatible suffixes. Verify pinout compatibility between 6-lead and 5-lead variants if substituting with different package options within the same family.

Analog Switches, Multiplexers, Demultiplexers FAQ

How does the supply voltage affect the on resistance?

The on resistance increases as the supply voltage decreases. At 1.8 V operation, the typical on resistance rises to approximately 40 Ω, compared to 2 Ω at higher voltages.

What is the difference between the ADG741 and ADG742?

The ADG741 contains a single SPST switch channel, while the ADG742 contains two SPST switch channels. They share similar electrical specifications but have different pin configurations.

Is the ADG741BKS-REEL lead-free?

No, the standard ADG741BKS-REEL is not explicitly marked as lead-free in the ordering guide. Lead-free versions are designated with a 'Z' suffix, such as ADG741BKSZ-REEL.
