MAX9034ASD Equivalent & Substitute Parts

Part Overview

The MAX9034ASD is a general-purpose comparator IC manufactured by Analog Devices Inc./Maxim Integrated, featuring four independent comparator elements in a 14-SOIC surface-mount package. The device operates across a 2.5V to 5.5V supply range with push-pull, rail-to-rail output configuration. The MAX9034ASD is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MAX9034ASD are identified based on the following critical parameters that determine functional equivalence:

Primary Substitution Criteria:

• Number of comparator elements: 4
• Package type: 14-SOIC surface-mount
• Operating temperature range: -40°C to 125°C
• Supply voltage compatibility: Overlapping or compatible ranges
• RoHS3 compliance status

Substitution Categories:

Direct Packaging Equivalent (MAX9034ASD+): Identical electrical specifications and packaging. Differs only in product status (Active vs. Obsolete) and packaging format (Tube vs. standard).

Functional Alternative (TS334IDT): Meets core substitution criteria with four comparator elements in 14-SOIC package and identical operating temperature range. Output type differs (Open-Drain vs. Push-Pull, Rail-to-Rail), requiring circuit-level evaluation for compatibility.

Parameter Comparison

Engineering Selection Recommendations

MAX9034ASD+ (Direct Equivalent): Select this part for direct replacement of MAX9034ASD. Electrical specifications and package dimensions are identical. The part is in Active product status, ensuring long-term availability and supply chain stability. ROHS3 compliance and identical certifications (REACH Unaffected, EAR99 ECCN) maintain regulatory alignment.

TS334IDT (Functional Alternative): This STMicroelectronics part provides an active-status alternative with identical package form factor and operating temperature range. Key differences include open-drain output configuration (versus push-pull, rail-to-rail), lower input offset voltage specification (5mV vs. 1mV), reduced quiescent current (26µA vs. 55µA), and lower CMRR (79dB vs. 100dB). Circuit topology must accommodate open-drain output characteristics. This part is suitable for applications where output configuration flexibility exists and lower power consumption is beneficial.

Frequently Asked Questions (FAQ)

Q: Can MAX9034ASD+ be used as a direct drop-in replacement for MAX9034ASD?

A: Yes. MAX9034ASD+ provides identical electrical performance and package specifications. The only differences are product status (Active vs. Obsolete) and packaging format (Tube). No circuit modifications are required.

Q: What is the primary difference between MAX9034ASD and TS334IDT?

A: The output stage configuration differs. MAX9034ASD features push-pull, rail-to-rail outputs, while TS334IDT uses open-drain outputs. This affects circuit design requirements, particularly for pull-up resistor implementation and output voltage swing characteristics.

Q: Is TS334IDT compatible with existing MAX9034ASD designs?

A: Compatibility depends on circuit topology. The open-drain output of TS334IDT requires external pull-up resistors and cannot drive outputs to the positive supply rail without modification. Applications designed for push-pull outputs must be re-evaluated.

Q: Are all three parts in the same package?

A: Yes. MAX9034ASD, MAX9034ASD+, and TS334IDT all use 14-SOIC (0.154", 3.90mm Width) surface-mount packaging with identical pin assignments for the four comparator elements.

Q: What is the supply voltage compatibility range across these parts?

A: MAX9034ASD and MAX9034ASD+ operate at 2.5V to 5.5V. TS334IDT operates at 1.6V to 5V, providing extended low-voltage capability. All three support standard 5V and 3.3V supply rails.

Q: Do all parts meet current RoHS and REACH requirements?

A: Yes. MAX9034ASD, MAX9034ASD+, and TS334IDT are all ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory standards.
