ADG802BRT-REEL7

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG802BRT-REEL7 is a monolithic CMOS single-pole, single-throw (SPST) switch with normally closed contacts. It operates on a single supply voltage ranging from 1.8 V to 5.5 V and supports an automotive temperature range of −40°C to +125°C. The device features a maximum on resistance of 0.4 Ω at 125°C and a maximum on resistance flatness of 0.08 Ω at the same temperature. It provides a current-carrying capability of 400 mA and switching times of 35 ns. The component is housed in a 6-lead SOT-23 package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix REEL7 corresponds to the required tape and reel packaging format. Confirm that the BRT designation matches the intended 6-lead SOT-23 package variant. Ensure the component meets RoHS compliance requirements if applicable to the manufacturing process. Cross-reference the part number against the manufacturer's latest ordering guide to confirm availability and specifications.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a normally closed analog switch is required within a 1.8 V to 5.5 V supply range. The ADG802 is pin-compatible with the ADG702, facilitating direct upgrades or replacements in existing designs. Consider the 400 mA current capacity and low on resistance for high-performance signal paths. Verify that the 6-lead SOT-23 package dimensions fit the available board space constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

The ADG802 is part of the ADG801/ADG802 family of submicron CMOS switches designed for low on resistance and high speed. Unlike the ADG801 which is normally open, the ADG802 provides a normally closed state by default. This family offers pin compatibility with the older ADG701/ADG702 series, allowing for straightforward design transitions while benefiting from improved electrical characteristics.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The ADG802BRMZ serves as a pin-compatible alternative in an 8-lead MSOP package. The ADG702 is a legacy equivalent offering similar functionality but may differ in specific electrical parameters.
