ADM698AR Equivalent & Substitute Parts

Part Overview

The ADM698AR is a supervisor integrated circuit from Analog Devices Inc. designed for power management applications. It functions as a simple reset/power-on reset controller with push-pull output configuration, monitoring a single voltage threshold at 4.65V. The ADM698AR is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production requirements. Substitute parts must maintain functional equivalence across voltage monitoring, reset timing, and output characteristics while accommodating modern product status and packaging options.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the ADM698AR is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Parameters:

• Voltage threshold: 4.65V
• Number of voltages monitored: 1
• Reset timeout: 140ms minimum
• Reset logic: Active High/Active Low
• Package / Case: 16-SOIC (0.295", 7.50mm Width)
• Mounting type: Surface Mount
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variations:

• Output configuration (Push-Pull vs. Open Drain) represents a functional difference that may be acceptable depending on circuit design requirements
• Operating temperature range may differ; parts with narrower ranges (-40°C to 85°C vs. 0°C to 70°C) represent a constraint
• Product status (Active vs. Obsolete) affects availability and long-term support
• Packaging format (Tube vs. Tape & Reel) affects handling and assembly processes

The ADM699ARZ is a parametric equivalent with identical electrical specifications and active product status. The MAX698 series parts (MAX698CWE+, MAX698CWE+T, MAX698EWE+) are similar substitutes with output configuration differences that require circuit-level evaluation.

Parameter Comparison

Engineering Selection Recommendations

ADM699ARZ is the primary substitute for ADM698AR. It maintains identical electrical parameters, voltage threshold, reset timing, and output configuration. The ADM699ARZ carries active product status with ROHS3 compliance and REACH unaffected certification, ensuring long-term availability and regulatory alignment for new designs.

MAX698CWE+, MAX698CWE+T, and MAX698EWE+ are functional alternatives with output configuration differences. These parts feature open-drain output instead of push-pull configuration. Selection of MAX698 variants requires circuit-level verification to confirm compatibility with the existing reset signal interface. MAX698EWE+ maintains the full operating temperature range (-40°C to 85°C) matching the ADM698AR, while MAX698CWE+ and MAX698CWE+T operate within a narrower range (0°C to 70°C). All MAX698 variants carry active product status with ROHS3 compliance.

Packaging format selection depends on assembly requirements: tube packaging for manual or low-volume assembly, tape & reel for automated high-volume production.

Frequently Asked Questions (FAQ)

Q: Can ADM699ARZ directly replace ADM698AR without circuit modification?

A: Yes. The ADM699ARZ maintains identical electrical specifications, voltage threshold (4.65V), reset timeout (140ms minimum), output configuration (push-pull), and operating temperature range (-40°C to 85°C). Direct substitution is supported at the component level.

Q: What is the key difference between ADM699ARZ and MAX698 series parts?

A: The primary difference is output configuration. ADM699ARZ provides push-pull output matching the ADM698AR. MAX698 series parts (MAX698CWE+, MAX698CWE+T, MAX698EWE+) feature open-drain output instead. This difference requires circuit-level evaluation to confirm compatibility with the reset signal interface in the target application.

Q: Are there temperature range constraints when selecting a substitute?

A: Yes. ADM698AR and ADM699ARZ operate across -40°C to 85°C. MAX698CWE+ and MAX698CWE+T operate within a narrower range (0°C to 70°C), which may not be suitable for applications requiring extended low-temperature operation. MAX698EWE+ matches the full temperature range of the original part.

Q: What packaging options are available for substitutes?

A: ADM699ARZ is supplied in tube packaging. MAX698 series parts are available in both tube (MAX698CWE+, MAX698EWE+) and tape & reel formats (MAX698CWE+T). Tape & reel packaging is recommended for automated assembly processes.

Q: Are all substitute parts RoHS compliant?

A: ADM699ARZ and all MAX698 variants (MAX698CWE+, MAX698CWE+T, MAX698EWE+) are ROHS3 compliant. The original ADM698AR does not specify RoHS status.

Q: Why is ADM698AR classified as obsolete?

A: Obsolete status indicates the part is no longer in active production. ADM699ARZ and MAX698 series alternatives are active products with ongoing manufacturer support and availability.
