ADG728BRU-REEL7

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG728BRU-REEL7 is an 8-channel CMOS analog matrix switch featuring a 2-wire serial interface compatible with the I²C standard. It operates on a single supply voltage ranging from 2.7 V to 5.5 V and is housed in a 16-lead TSSOP package. The device provides a typical on-resistance of 2.5 Ω at 5 V and 6 Ω at 3 V, with a maximum of 4.5 Ω and 11 Ω respectively. It supports a -3 dB bandwidth of 65 MHz, exhibits a charge injection of ±3 pC, and includes guaranteed break-before-make switching action. The operating temperature range extends from -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Serially controlled via a 2-wire I²C-compatible interface allowing independent channel configuration.
• Capable of functioning as multiplexers, demultiplexers, or switch arrays with any combination of channels active.
• Ensures signal integrity through guaranteed break-before-make switching to prevent momentary shorting.

Analog Switches, Multiplexers, Demultiplexers Applications

• Data acquisition systems requiring flexible signal routing
• Programmable gain amplifier input selection
• Test and measurement equipment signal conditioning

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify that the specific ordering suffix corresponds to the reel packaging format required for automated assembly processes. Confirm that the component version matches the industrial temperature grade specifications necessary for the intended operational environment. Ensure compatibility with the target system's serial bus voltage levels before integration.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when an 8-channel matrix topology is required rather than a simple multiplexer configuration. The choice is appropriate for designs needing independent control over multiple signal paths via a serial interface. Consider the 16-lead TSSOP package constraints regarding board space and thermal dissipation requirements during the layout phase.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the ADG728/ADG729 family of low-voltage CMOS matrix switches manufactured by Analog Devices Inc. The ADG728 variant specifically provides eight independently controllable switches, whereas the ADG729 offers two sets of four channels. Both share identical serial control logic and pinout structures within the 16-lead TSSOP form factor.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The ADG728BRUZ serves as a RoHS-compliant alternative within the same package type. Other series members like the ADG708 offer similar multiplexing functions but utilize parallel addressing rather than serial control.
