ADG721BRMZ-REEL7

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG721BRMZ-REEL7 is a dual 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 maximum on resistance of 4 Ω with low flatness. The device provides a −3 dB bandwidth exceeding 200 MHz, ensuring high-frequency signal integrity. Switching times are characterized by a maximum turn-on time of 20 ns and a maximum turn-off time of 10 ns. Power consumption is minimal, with a maximum supply current of 1 μA. The component is housed in an 8-lead MSOP package and supports an industrial operating temperature range from −40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix REEL7 corresponds to tape-and-reel packaging when sourcing components. Confirm RoHS compliance status indicated by the Z suffix in the base part number. Ensure the supplier documentation matches the Rev E datasheet specifications for accurate electrical parameter validation prior to integration.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for designs requiring low on resistance and high bandwidth within a compact surface-mount footprint. Consider the 8-lead MSOP package constraints for PCB layout. Evaluate the 1.8 V to 5.5 V supply range against system power requirements. Verify that the 4 Ω maximum on resistance meets the voltage drop limitations of the target application circuit.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the ADG721/ADG722/ADG723 family of general-purpose CMOS switches. The ADG721 variant specifically offers two independent SPST channels without break-before-make timing. It shares core architectural features with the ADG722 and ADG723 but differs in logic control configurations. The family is designed for low-voltage, low-power analog signal switching applications.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The ADG721BRM serves as the non-RoHS compliant equivalent with identical electrical characteristics. The ADG721ACPZ variants offer the same functionality in a 3 mm × 2 mm LFCSP package instead of the MSOP form factor. Cross-reference pinouts and thermal impedance values when substituting package types.
