ADM699AN Equivalent & Substitute Parts

Part Overview

The ADM699AN is a supervisor integrated circuit from Analog Devices Inc. designed for power management applications. It functions as a simple reset/power-on reset device with push-pull output configuration, monitoring a single voltage threshold at 4.65V. The ADM699AN is classified as obsolete, making equivalent and substitute parts necessary for ongoing system support and new design implementations. Substitute parts maintain core functionality while offering active product status and improved availability.

Substitute Part Grouping Explanation

Substitute parts for the ADM699AN are categorized based on electrical and mechanical compatibility. The primary substitution criteria are:

Direct Equivalents maintain identical electrical specifications: single voltage monitoring at 4.65V threshold, push-pull output configuration, active high/active low reset logic, 140ms minimum reset timeout, and 8-PDIP package format. These parts are pin-compatible and functionally interchangeable.

Parametric Equivalents share all critical electrical parameters but may differ in output configuration or temperature range. Parts with open drain/open collector output require circuit-level evaluation for compatibility with push-pull designs.

Similar Parts maintain core supervisor functionality with identical voltage thresholds, reset timing, and package format but differ in output type or operating temperature specifications.

Engineering Selection Recommendations

Direct Replacement (Recommended for Obsolete Part Mitigation): ADM699ANZ is the primary substitute for ADM699AN. Both parts are manufactured by Analog Devices Inc. with identical electrical specifications, output configuration, and operating temperature range. ADM699ANZ holds active product status with ROHS3 compliance and REACH unaffected certification, ensuring long-term availability and regulatory compliance.

Alternative Direct Replacement: MAX707EPA+ provides equivalent functionality with push-pull output and active high/active low reset logic. This part maintains the full operating temperature range (-40°C ~ 85°C) and offers active product status with ROHS3 compliance.

Output Configuration Consideration: MAX699CPA+ and MAX699EPA+ feature open drain/open collector output instead of push-pull configuration. These parts are suitable only for applications where the circuit design accommodates open drain/open collector logic levels. MAX699EPA+ supports the extended temperature range (-40°C ~ 85°C), while MAX699CPA+ operates within 0°C ~ 70°C.

Parametric Equivalent: ADM698ANZ shares all critical electrical parameters with ADM699AN and offers the highest current inventory (2400 pcs). This part is suitable for applications where the base product number change is acceptable.

Frequently Asked Questions (FAQ)

Q: Can ADM699ANZ directly replace ADM699AN without circuit modification? A: Yes. ADM699ANZ is a direct equivalent with identical voltage threshold (4.65V), push-pull output configuration, active high/active low reset logic, 140ms reset timeout, and 8-PDIP package. No circuit modification is required.

Q: What is the difference between push-pull and open drain/open collector output? A: Push-pull output actively drives both high and low logic states. Open drain/open collector output can only pull low; the high state requires an external pull-up resistor. Circuit compatibility depends on the application's output stage design.

Q: Is MAX707EPA+ compatible with ADM699AN applications? A: MAX707EPA+ is electrically compatible with identical voltage threshold, reset timing, and operating temperature range. Both parts feature push-pull output and active high/active low reset logic. The base product number differs (MAX707 vs. ADM699), but functional compatibility is maintained.

Q: Why does MAX699CPA+ have a narrower operating temperature range? A: MAX699CPA+ operates from 0°C ~ 70°C, compared to ADM699AN's -40°C ~ 85°C range. Applications requiring extended temperature operation must use MAX699EPA+ or ADM699ANZ.

Q: Are all substitute parts ROHS3 compliant? A: All active substitute parts listed (ADM699ANZ, ADM698ANZ, MAX699CPA+, MAX699EPA+, MAX707EPA+) are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the package compatibility across all parts? A: All parts use 8-PDIP (0.300", 7.62mm) through-hole packaging with 8-PDIP supplier device package designation. Physical and electrical pin compatibility is maintained across all listed substitutes.
