ADM690AQ Equivalent & Substitute Parts

Part Overview

The ADM690AQ is a Power Management Integrated Circuit (PMIC) functioning as a supervisor with push-pull, totem pole output configuration. This device monitors a single voltage channel and provides active-low reset functionality with a 35ms minimum reset timeout. The ADM690AQ is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system support and new design implementations. Substitute parts must maintain identical electrical characteristics and package compatibility to ensure direct replacement capability.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ADM690AQ are identified based on strict equivalence across the following critical parameters:

• Single voltage channel monitoring capability
• 4.65V voltage threshold setting
• Push-pull, totem pole output configuration
• Active-low reset logic with 35ms minimum timeout
• 8-CDIP (0.300", 7.62mm) through-hole package
• 8-CERDIP supplier device package designation
• Moisture Sensitivity Level 1 (Unlimited)

The ADM690SQ and MAX690EJA meet all electrical and mechanical substitution criteria. Both devices maintain identical functional specifications and package compatibility with the ADM690AQ. The ADM690SQ offers extended operating temperature range (-55°C ~ 125°C) and active product status. The MAX690EJA provides equivalent performance within the original temperature specification (-40°C ~ 85°C) and active product status.

Parameter Comparison

Engineering Selection Recommendations

For applications currently using the ADM690AQ, the ADM690SQ is the primary substitute. This part maintains all electrical equivalence while offering active product status and extended operating temperature range (-55°C ~ 125°C), providing greater environmental flexibility. The ADM690SQ carries ROHS3 compliance and REACH unaffected status, meeting modern regulatory requirements.

The MAX690EJA serves as an alternative substitute when ADM690SQ availability is constrained. This part provides identical electrical performance and package compatibility within the original temperature specification (-40°C ~ 85°C). The MAX690EJA also carries ROHS3 compliance and REACH unaffected status.

Both substitute parts are active products with established supply chains, eliminating obsolescence risk associated with the ADM690AQ.

Frequently Asked Questions (FAQ)

Q: Can the ADM690SQ directly replace the ADM690AQ in existing designs?

A: Yes. The ADM690SQ maintains identical electrical specifications including voltage threshold (4.65V), output configuration (push-pull, totem pole), reset logic (active low), and reset timeout (35ms minimum). Package compatibility is confirmed: both use 8-CDIP (0.300", 7.62mm) through-hole mounting with 8-CERDIP supplier designation. No circuit modifications are required.

Q: What is the primary advantage of the ADM690SQ over the ADM690AQ?

A: The ADM690SQ offers extended operating temperature range (-55°C ~ 125°C) compared to the ADM690AQ (-40°C ~ 85°C), providing broader environmental applicability. Additionally, the ADM690SQ maintains active product status with established supply availability, whereas the ADM690AQ is obsolete.

Q: Is the MAX690EJA suitable for applications requiring the original temperature specification?

A: Yes. The MAX690EJA operates within the original ADM690AQ temperature range (-40°C ~ 85°C) while maintaining all electrical equivalence. This part is appropriate for designs with temperature constraints matching the original specification.

Q: Are there packaging differences between these parts?

A: No. All three parts use identical 8-CDIP (0.300", 7.62mm) through-hole packages with 8-CERDIP supplier designation. Direct socket compatibility is confirmed.

Q: Do the substitute parts meet current regulatory compliance?

A: Yes. Both the ADM690SQ and MAX690EJA carry ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements. The ADM690AQ compliance status was not specified in available documentation.
