ADG752BRMZ-REEL7

Overview

The ADG752BRMZ-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. Off isolation reaches –80 dB at 30 MHz. Switching times are typically 8 ns for turn-on and 3 ns for turn-off. It utilizes TTL/CMOS compatible logic inputs and is housed in an 8-lead MSOP package.

Feature Summary

• T-switch architecture provides enhanced off isolation while maintaining frequency response.
• Fully bidirectional switching capability handles signals up to the supply rails.
• Break-before-make action prevents momentary shorting during channel transitions.
• Low power dissipation suitable for battery-powered portable instruments.

Applications

• Audio and video signal routing
• RF switching applications
• Networking equipment
• Communication systems
• Sample-and-hold circuits

Procurement Notes

Verify the specific ordering suffix REEL7 indicates tape and reel packaging when sourcing this component. Confirm the B version designation corresponds to the industrial temperature range of -40°C to +85°C. Ensure compatibility with the 8-lead MSOP footprint during procurement planning.

Selection Notes

Select this component for designs requiring high off-isolation and wide bandwidth in a compact form factor. The low on-resistance and flatness ensure minimal signal distortion. Verify that the single-supply operation aligns with the system's power constraints and that the logic levels match the control interface requirements.

Part Context

This part belongs to the ADG752 series of CMOS analog switches. It shares functional similarities with other low-voltage RF switches but is distinguished by its specific T-switch topology and 250 MHz bandwidth. The BRMZ variant specifically denotes the MSOP package option within the product line.

Replacement Considerations

Direct replacements include ADG752BRM-REEL and ADG752BRTZ-REEL7, which share identical electrical specifications. Note that the RT variants utilize a 6-lead SOT-23 package, requiring PCB layout adjustments compared to the 8-lead MSOP format.

FAQ

What is the maximum continuous current allowed through the source or drain terminals?

The maximum continuous current for the Source (S) or Drain (D) terminals is 30 mA.

How does the T-switch configuration improve performance?

The T-switch configuration uses a shunt switch to ground when off, providing a path for unwanted signals and resulting in higher off-isolation compared to standard series switches.

Is the ADG752BRMZ-REEL7 RoHS compliant?

Yes, parts with the 'Z' suffix in the model number, such as ADG752BRMZ, are RoHS compliant according to the manufacturer's ordering guide.
