ADG721BRM-REEL

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG721BRM-REEL 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. The device provides a -3 dB bandwidth exceeding 200 MHz, with switching times of 20 ns for turn-on and 10 ns for turn-off. It 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 against official documentation to confirm packaging type. The REEL suffix indicates tape and reel packaging intended for automated surface-mount assembly processes. Ensure compatibility with standard SMD/SMT manufacturing equipment specifications before procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when designing circuits that require low on-resistance and fast switching speeds within a compact footprint. Verify that the system's single supply voltage falls within the 1.8 V to 5.5 V operational range. Confirm that the 8-lead MSOP package dimensions align with the printed circuit board layout constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the ADG721/ADG722/ADG723 family of general-purpose CMOS switches. While sharing similar electrical characteristics, the ADG721 specifically functions as two independent SPST switches without break-before-make timing. This distinguishes it from the ADG723, which includes overlap protection features.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The ADG721BRMZ serves as a lead-free RoHS-compliant alternative within the same package configuration. Other family members like the ADG722 or ADG723 offer different internal switching configurations but share identical pinouts and electrical performance metrics.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the maximum analog signal range supported by the ADG721?

The analog signal range extends from ground (0 V) to the positive supply voltage (VDD).

Does the ADG721 support break-before-make switching?

No, the ADG721 consists of two independent SPST switches. Break-before-make functionality is exclusive to the ADG723 model.

How does the supply voltage affect the on-resistance?

Lower supply voltages result in higher on-resistance values. For instance, at 1.8 V, the typical on-resistance increases significantly compared to operation at 5 V.
