ADG702BRM-REEL7

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG702BRM-REEL7 is a CMOS single-pole single-throw (SPST) analog switch from Analog Devices, housed in an 8-lead MSOP package. It operates on a single supply voltage ranging from 1.8 V to 5.5 V. Key electrical parameters include a typical on resistance of 2 Ω and a maximum of 4 Ω at 25°C, extending to 6 Ω across the industrial temperature range of -40°C to +85°C. The device features a -3 dB bandwidth exceeding 200 MHz, with switching times of 18 ns maximum for turn-on and 12 ns maximum for turn-off. Power consumption is minimal, with a typical supply current of 0.001 μA.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix to confirm package type and lead-free status, as the ADG702 series includes variants such as BRJZ and BRTZ. Confirm that the REEL7 designation corresponds to the required tape and reel quantity for manufacturing integration. Check current availability status, as distribution channels may list end-of-life or limited stock notifications for specific reel configurations.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the ADG702BRM-REEL7 when a single-channel SPST configuration is required within a compact 8-lead MSOP footprint. Ensure the application voltage stays within the 1.8 V to 5.5 V range to maintain specified on resistance and bandwidth characteristics. Consider the 2 Ω typical on resistance for minimizing insertion loss in sensitive signal paths. Verify thermal requirements against the 315 mW power dissipation rating for the MSOP package.

Analog Switches, Multiplexers, Demultiplexers Part Context

The ADG702 belongs to the Analog Devices family of general-purpose CMOS switches, designed alongside the ADG701. While the ADG701 is configured as a normally open switch, the ADG702 provides complementary functionality within the same low-voltage, high-performance architecture. Both parts share identical electrical specifications regarding speed, leakage, and power consumption, differing primarily in their default logic states.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct functional replacements within the same package include other ADG702 variants such as ADG702BRMZ-REEL7 or ADG702BRTZ-REEL7, provided the pinout compatibility is verified. Cross-family substitution with ADG701 requires attention to the normally open versus normally closed logic configuration. Ensure any substitute maintains the 1.8 V to 5.5 V operating range and comparable on resistance specifications.
