ADG812YRUZ-REEL7

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG812YRUZ-REEL7 is a low-voltage complementary metal-oxide semiconductor (CMOS) device containing four independently selectable single-pole/single-throw (SPST) switches. It operates on a single supply voltage ranging from 1.65 V to 3.6 V and supports an automotive temperature range of −40°C to +125°C. The switches offer an ultralow on resistance of less than 0.8 Ω over the full temperature range, with a maximum continuous current carrying capability of 300 mA. Digital inputs are compatible with 1.8 V logic when powered by a 2.7 V to 3.6 V supply. The device features fast switching times under 25 ns, typical power consumption below 0.1 µW, and rail-to-rail switching operation.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix REEL7 corresponds to the reel packaging configuration required for automated assembly processes. Confirm that the Y suffix indicates compliance with the specified automotive temperature range of −40°C to +125°C. Ensure the RoHS compliant status aligns with environmental regulations applicable to the manufacturing region. Cross-reference the manufacturer part number with official Analog Devices documentation to validate component authenticity and revision level.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when designing circuits requiring low-voltage analog signal switching with minimal insertion loss. The ADG812 variant is appropriate when logic high signals are needed to activate the switches, distinguishing it from the ADG811 which uses inverted logic. Consider the 16-lead TSSOP package dimensions for board space constraints. Evaluate the 300 mA continuous current rating against the maximum load requirements of the application to ensure reliable operation without exceeding absolute maximum ratings.

Analog Switches, Multiplexers, Demultiplexers Part Context

The ADG812YRUZ-REEL7 belongs to the ADG811/ADG812 family of low-voltage CMOS analog switches manufactured by Analog Devices Inc. This series is designed for portable and battery-powered applications where low power consumption and small form factors are critical. The ADG812 differs from the ADG811 solely in its digital control logic polarity. Both devices share identical electrical characteristics and pin configurations, offering flexibility in system design based on existing logic levels.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The ADG811YRUZ-REEL7 serves as a functional substitute if the control logic polarity can be inverted within the system design. Verify that any replacement maintains the same 16-lead TSSOP footprint and thermal characteristics. Ensure the alternative component meets the 1.65 V to 3.6 V supply range and automotive temperature specifications.
