ADG738BRUZ-REEL7

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG738BRUZ-REEL7 is a CMOS analog matrix switch featuring an 8-to-1 multiplexer configuration housed in a 16-lead TSSOP package. It operates on a single supply voltage ranging from 2.7 V to 5.5 V and utilizes a 3-wire serial interface compatible with SPI, QSPI, and MICROWIRE standards. The device guarantees a maximum on-resistance of 4.5 Ω at 25°C and maintains a typical on-resistance flatness of 0.75 Ω. Key electrical specifications include a maximum leakage current of 0.3 nA, a switching time (tON) of 32 ns, and a break-before-make delay of 1 ns. The component supports digital input currents up to 0.1 µA and functions within an industrial temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Features a 3-wire serial interface compatible with standard microprocessor protocols for simplified control.
• Provides guaranteed break-before-make switching action to prevent momentary shorting during channel transitions.
• Includes a power-on reset function that initializes all switches to the off state upon startup.
• Supports daisy-chaining multiple devices via the DOUT pin for expanded system scalability.

Analog Switches, Multiplexers, Demultiplexers Applications

• Data acquisition systems
• Communication systems
• Relay replacement circuits
• Audio and video signal routing

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix REEL7 corresponds to the required tape and reel packaging format before ordering. Confirm that the B version industrial temperature rating (-40°C to +85°C) meets the operational requirements of the target environment. Ensure the 16-lead TSSOP footprint matches the PCB layout constraints. Cross-reference the datasheet revision A specifications against the latest manufacturer documentation to confirm parameter stability.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when an 8-channel multiplexing solution with serial control is required. The low on-resistance and flatness make it suitable for precision signal paths. Consider the ADG739 if a dual 4-channel configuration is preferred instead. Verify that the 30 MHz serial clock speed aligns with the host processor's capabilities. Ensure the single-supply operation fits within the available voltage rails of the design.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the ADG738/ADG739 family of low-voltage, serially controlled CMOS matrix switches manufactured by Analog Devices Inc. The series is designed for applications requiring flexible signal routing with minimal external logic. The BRUZ designation indicates the specific temperature grade and surface-mount package type within the broader product line.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The ADG739BRUZ-REEL7 serves as a functional substitute within the same family, offering a dual 4-channel configuration rather than an 8-channel setup. Both parts share identical pinouts, serial interface protocols, and package dimensions, facilitating direct board-level interchangeability where channel count permits.
