ADG812YRU-REEL7

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG812YRU-REEL7 is a low voltage CMOS device containing four independently selectable single-pole/single-throw (SPST) switches. It operates on a single supply ranging from 1.65 V to 3.6 V and supports digital inputs compatible with 1.8 V logic when powered between 2.7 V and 3.6 V. The component features an ultralow on resistance of less than 0.8 Ω maximum over the full automotive temperature range of –40°C to +125°C. It provides high current carrying capability, supporting up to 300 mA continuous current at 3.3 V operation. The switches conduct equally well in both directions and allow rail-to-rail switching operation.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the packaging format. The REEL7 designation indicates tape and reel packaging intended for automated assembly processes. Ensure the component meets the required environmental specifications for the target application environment before finalizing procurement decisions.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for designs requiring low voltage operation and high current capacity. The ADG812 variant requires a logic high input to activate the switches, distinguishing it from the ADG811 which uses logic low activation. Confirm that the system's digital control signals align with the required logic levels for reliable switch actuation within the specified voltage range.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the ADG811/ADG812/ADG813 family of low voltage CMOS analog switches. All members share identical electrical characteristics and package options, differing only in their digital control logic polarity. The ADG812 specifically utilizes non-inverted logic where a high input turns the switch on, providing design flexibility for interface compatibility.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The ADG811YRU-REEL7 and ADG813YRU-REEL7 are direct functional substitutes within the same package. Selection depends on the required logic polarity: use ADG811 for active-low control or ADG813 for mixed logic configurations. Verify that the replacement matches the specific REEL7 packaging requirement for the manufacturing line.

Analog Switches, Multiplexers, Demultiplexers FAQ

How does the ADG812 differ from the ADG811?

The ADG812 and ADG811 have identical electrical specifications but differ in control logic. The ADG812 switches turn on with a logic high input, whereas the ADG811 switches turn on with a logic low input.

What is the maximum continuous current rating?

The device supports a continuous current of 300 mA at 3.3 V operation. Lower voltages such as 2.5 V and 1.8 V support slightly lower continuous currents of 275 mA and 250 mA, respectively.

Does the ADG812 exhibit break-before-make switching action?

No, the ADG812 does not feature break-before-make switching. This characteristic is exclusive to the ADG813 model within this product family.
