ADG751ART-REEL

Overview

The ADG751ART-REEL is a low voltage single pole single throw (SPST) analog switch manufactured by Analog Devices Inc. It utilizes a T-switch configuration to achieve high off isolation and wide signal bandwidth. The device operates on a single supply ranging from +1.8 V to +5.5 V with typical power consumption below 0.01 mW. Key electrical parameters include an on-resistance of 15 Ω maximum at +5 V, a –3 dB signal bandwidth of 300 MHz, and off isolation of –75 dB at 100 MHz. Switching times are typically 9 ns for turn-on and 3 ns for turn-off. The component is housed in a 6-lead SOT-23 package.

Feature Summary

• T-switch architecture provides enhanced off isolation while maintaining frequency response.
• Capable of handling bidirectional signals up to and including the supply rails.
• Compatible with TTL and CMOS logic levels for digital control inputs.

Applications

• Audio and video switching
• RF switching applications
• Networking equipment
• Battery powered portable instruments
• Communication systems

Procurement Notes

Verify the specific ordering suffix to confirm the package type and reel quantity. Confirm RoHS compliance status if required by the manufacturing process. Ensure the temperature range matches the operational environment requirements. Check for any recent product change notices that may affect pinout or specifications.

Selection Notes

Select this component when high off isolation and wide bandwidth are critical for RF or video signal routing. The low power consumption makes it suitable for battery-operated devices. Verify that the supply voltage range aligns with the system design. Consider the thermal impedance characteristics for proper heat dissipation in the chosen package.

Part Context

This part belongs to the ADG751 family of low voltage SPST switches. The ART variant specifically denotes the 6-lead Small Outline Transistor Package. Other variants in the series include the ARMZ version in an 8-lead Mini Small Outline Package. The family shares similar electrical characteristics but differs in physical footprint and pin count.

Replacement Considerations

Direct replacements within the same family include the ADG751ARMZ for an 8-lead option. Cross-family substitutes require verification of pin compatibility and electrical performance matching. Ensure the alternative device supports the required single supply voltage range and signal bandwidth.
