ADG751BRMZ

Overview

The ADG751BRMZ 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 of -75 dB at 100 MHz and a -3 dB signal bandwidth of 300 MHz. The device operates on a single supply ranging from +1.8 V to +5.5 V with typical power consumption below 0.01 mW. It features fast switching times, with turn-on typically at 9 ns and turn-off at 3 ns. The component is available in an 8-lead mini small outline package (mSOIC).

Feature Summary

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

Applications

• Audio and video signal routing
• RF switching applications
• Battery powered portable instruments

Procurement Notes

Verify the specific ordering suffix to confirm the package type and reel specifications. Ensure the procurement documentation matches the required temperature range and RoHS compliance status indicated in the manufacturer's ordering guide before finalizing acquisition.

Selection Notes

Select this component when high isolation and wide bandwidth are critical for RF or video paths within low voltage systems. Consider the 8-lead mSOIC package constraints and thermal impedance values during PCB layout planning to ensure reliable operation across the specified industrial temperature range.

Part Context

This part belongs to the ADG751 series of CMOS low voltage switches. The BRMZ designation indicates the B grade performance level packaged in an 8-lead mini small outline format. It is designed for submicron process technology to balance low power dissipation with high switching speed.

Replacement Considerations

Direct substitutes include other ADG751 variants such as ADG751ARMZ or ADG751ARTZ, provided the package footprint and pinout compatibility are verified against the current design requirements.

FAQ

What is the maximum continuous current rating for the source or drain terminals?

The absolute maximum ratings specify a continuous current limit of 30 mA for either the source or drain terminal.

How does the T-switch configuration improve performance compared to standard series switches?

The T-switch configuration uses a shunt switch to ground when the series switches are open, providing a path for unwanted signals and resulting in significantly higher off-isolation than ordinary series switches.

Is the ADG751 suitable for dual-supply operation?

No, the datasheet specifies that the ADG751 is designed for single supply operation ranging from +1.8 V to +5.5 V.
