ADG701LBRM Equivalent & Substitute Parts

Part Overview

The ADG701LBRM is a single-pole single-throw (SPST) normally-open IC switch manufactured by Analog Devices Inc., designed for high-speed analog signal switching applications. This component features a 3Ohm on-state resistance and operates across a 1.8V to 5V supply voltage range, making it suitable for precision signal routing in mixed-signal systems.

The ADG701LBRM is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain reliability, and support ongoing production or maintenance of systems utilizing this component.

Substitute Part Grouping Explanation

Substitution eligibility for the ADG701LBRM is determined by the following critical parameters:

Switch Circuit Configuration: SPST - NO topology
Circuit Count: Single circuit (1:1 multiplexer/demultiplexer)
On-State Resistance: Maximum 3Ohm
Supply Voltage Range: 1.8V ~ 5V compatibility
Switching Speed: Ton/Toff performance within acceptable margins
Bandwidth: Minimum 200MHz operation
Leakage Current: Maximum 250pA
Package Compatibility: 8-MSOP surface mount form factor
Operating Temperature Range: -40°C ~ 85°C

Substitute parts are grouped into two categories:

Direct Equivalent: Parts with identical electrical specifications and packaging, differing only in product status or packaging format.

Functional Equivalent: Parts meeting all critical electrical parameters with minor variations in secondary specifications (such as on-state resistance tolerance or switching time), while maintaining full functional compatibility within the defined operating envelope.

Engineering Selection Recommendations

ADG701LBRMZ is the primary substitute for the obsolete ADG701LBRM. This part is manufactured by Analog Devices Inc. and maintains identical electrical specifications across all critical parameters. The ADG701LBRMZ is currently in active production status with ROHS3 compliance and REACH unaffected certification, ensuring regulatory alignment and supply chain continuity. The component is available in tube packaging format.

MAX4645EUA+ serves as a functional equivalent manufactured by Analog Devices Inc./Maxim Integrated. This part meets all core switching requirements with a lower on-state resistance (2.5Ohm versus 3Ohm maximum), providing improved performance in signal path applications. Switching times are marginally extended (15ns/10ns versus 12ns/8ns typical), which remains within acceptable operational margins for most applications. The MAX4645EUA+ is actively produced, ROHS3 compliant, and REACH unaffected. Selection of this part is appropriate when lower on-state resistance provides system-level benefits.

Both substitute parts maintain identical supply voltage ranges, leakage current specifications, charge injection characteristics, and operating temperature ranges as the original ADG701LBRM, ensuring direct functional compatibility in existing designs.

Frequently Asked Questions (FAQ)

Q: Can ADG701LBRMZ be used as a direct replacement for ADG701LBRM?

A: Yes. The ADG701LBRMZ is a direct equivalent with identical electrical specifications. The primary difference is product status (active versus obsolete) and packaging format (tube). Both parts are manufactured by Analog Devices Inc. and share the same 8-MSOP package footprint.

Q: What is the key difference between ADG701LBRMZ and MAX4645EUA+?

A: The MAX4645EUA+ features a lower on-state resistance (2.5Ohm maximum versus 3Ohm) and slightly extended switching times (15ns/10ns versus 12ns/8ns typical). Both parts operate across the same 1.8V to 5V supply range and maintain identical leakage current and capacitance specifications. The MAX4645EUA+ is suitable when reduced on-state resistance improves system performance.

Q: Are all substitute parts compatible with the original PCB layout?

A: Yes. All substitute parts use the 8-MSOP surface mount package with identical 0.118" (3.00mm) width, ensuring direct footprint compatibility on existing printed circuit boards.

Q: Do the substitute parts meet current regulatory requirements?

A: Both ADG701LBRMZ and MAX4645EUA+ are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards. The original ADG701LBRM regulatory status is not specified in available documentation.

Q: What is the operating temperature range for substitute parts?

A: Both substitute parts operate across -40°C to 85°C (TA), matching the original ADG701LBRM specification and supporting industrial and commercial temperature environments.
