ADG752BRTZ-REEL7

Overview

The ADG752BRTZ-REEL7 is a low voltage SPDT switch from Analog Devices, constructed using a T-switch configuration for high off isolation. It operates on a single supply ranging from +1.8 V to +5.5 V with typical power consumption under 0.01 mW. The device features an on-resistance of 15 Ω typically and 18 Ω maximum at +5 V, with a –3 dB signal bandwidth of 250 MHz. It offers –80 dB off isolation at 30 MHz and switching times of 8 ns (tON) and 3 ns (tOFF). Available in a 6-lead SOT-23 package, it supports industrial temperatures from -40°C to +85°C.

Feature Summary

• T-switch architecture provides high off isolation while maintaining good frequency response.
• Break-before-make switching action prevents momentary shorting between channels.
• Fully bidirectional operation handles signals up to and including the supply rails.
• Compatible with TTL and CMOS logic levels.

Applications

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

Procurement Notes

Verify the RoHS compliant suffix 'Z' in the part number against the manufacturer's ordering guide to ensure environmental compliance. Confirm the specific reel packaging designation matches project requirements. Check current lifecycle status as components may be subject to discontinuation notices. Validate that the 6-lead SOT-23 footprint aligns with existing PCB designs.

Selection Notes

Select this component when high off isolation and wide bandwidth are required for RF or video signals. Ensure the single supply voltage range meets system constraints. Consider the T-switch topology for superior isolation compared to standard series switches. Verify thermal impedance limits if operating near maximum temperature ranges.

Part Context

This part belongs to the ADG752 family of CMOS analog switches. It shares functional similarities with other low-voltage SPDT switches but is distinguished by its specific T-switch design and 250 MHz bandwidth. The B version indicates the industrial temperature grade. Other variants exist in different packages like the 8-lead MSOP.

Replacement Considerations

Direct substitutes include ADG752BRM-REEL and ADG752BRT-REEL. These share identical electrical specifications but differ in package type or reel quantity. Verify pinout compatibility before substitution.
