ADG752BRMZ

Overview

The ADG752BRMZ is a low voltage single pole double throw (SPDT) analog switch manufactured by Analog Devices Inc. It operates on a single supply ranging from +1.8 V to +5.5 V and features a T-switch configuration for high off isolation of -80 dB at 30 MHz. The device provides a typical on-resistance of 15 Ω, a -3 dB signal bandwidth of 250 MHz, and fast switching times with a typical turn-on time of 8 ns and turn-off time of 3 ns. Power consumption is typically less than 0.01 mW. It supports TTL/CMOS compatible logic inputs and utilizes an 8-lead mini small outline package.

Feature Summary

• T-switch architecture providing high off isolation while maintaining good frequency response in the ON condition.
• Low power dissipation suitable for battery-powered portable instruments.
• Fully bidirectional signal handling capability extending up to and including the supply rails.
• Break-before-make switching action to prevent momentary shorting during channel transitions.

Applications

• Audio and video signal switching
• RF and networking applications
• Relay replacement circuits
• Sample-and-hold systems

Procurement Notes

Verify the specific ordering suffix to confirm the package type and reel quantity. Ensure the component meets RoHS compliance requirements if applicable to your manufacturing process. Confirm that the industrial temperature range aligns with your system's operational environment before finalizing procurement orders.

Selection Notes

Select this component when high off isolation and wide bandwidth are required in a low voltage environment. Consider the 8-lead MSOP package for space-constrained designs. Evaluate the break-before-make timing characteristics to ensure compatibility with your multiplexing application requirements.

Part Context

The ADG752 belongs to Analog Devices' family of low voltage CMOS analog switches. It is designed using a submicron process to achieve high switching speeds and low on-resistance. The BRMZ variant specifically denotes the industrial temperature grade and the 8-lead mini small outline package format.

Replacement Considerations

Direct substitutes include other ADI SPDT switches such as the ADG704 or ADG708, provided they meet the voltage and isolation requirements. Verify pinout compatibility and thermal impedance specifications before implementing any cross-model replacements.

FAQ

What is the maximum analog signal range the ADG752 can handle?

The analog signal range extends from 0 V to VDD, allowing it to handle signals up to and including the positive supply rail.

How does the T-switch configuration benefit performance?

The T-switch configuration improves off isolation by providing a shunt path to ground for unwanted signals, resulting in better isolation than standard series switches.

Is the ADG752 suitable for high-frequency RF applications?

Yes, the device offers a -3 dB signal bandwidth of 250 MHz and high off isolation, making it suitable for RF and video signal switching.
