MAX1090ACEI Equivalent & Substitute Parts

Part Overview

The MAX1090ACEI is a 10-bit Analog-to-Digital Converter (ADC) manufactured by Analog Devices Inc./Maxim Integrated, designed for data acquisition applications. It features a Successive Approximation Register (SAR) architecture with 400 kSPS sampling rate, supporting 4 or 8 input channels with pseudo-differential and single-ended input configurations. The device operates with a 5V analog supply and 2.7V to 5.5V digital supply, housed in a 28-QSOP surface mount package.

The MAX1090ACEI is classified as obsolete. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support legacy system maintenance or redesigns requiring active component alternatives.

Substitute Part Grouping Explanation

Substitution for the MAX1090ACEI is determined by strict equivalence across the following critical parameters:

• 10-bit resolution
• 400 kSPS sampling rate
• 4 or 8 input channel configuration
• Pseudo-differential and single-ended input support
• SAR architecture with parallel data interface
• External and internal reference capability
• 5V analog supply and 2.7V to 5.5V digital supply range
• 28-QSOP package footprint
• Surface mount technology

The substitute parts identified maintain identical electrical specifications and mechanical compatibility, ensuring direct functional replacement in existing designs.

Engineering Selection Recommendations

For applications currently using the MAX1090ACEI, the MAX1090BCEI+ is the primary substitute. This part maintains full parametric equivalence across all specified electrical and mechanical characteristics while offering the advantage of active product status and ROHS3 compliance. The transition from the obsolete MAX1090ACEI to the MAX1090BCEI+ eliminates supply chain risk and aligns with current environmental and regulatory standards.

The MAX1090ACEI+ is also available as an active alternative with ROHS3 compliance. However, detailed parametric specifications for this variant are limited in the provided data, requiring verification of input channel configuration and input type compatibility before selection.

Both substitute parts are manufactured by Analog Devices Inc./Maxim Integrated, ensuring consistency in design support and technical documentation.

Frequently Asked Questions (FAQ)

Q: Can MAX1090BCEI+ directly replace MAX1090ACEI in existing designs?

A: Yes. The MAX1090BCEI+ maintains identical electrical specifications including 10-bit resolution, 400 kSPS sampling rate, 4/8 input channels, SAR architecture, and 28-QSOP package footprint. No circuit modifications are required for functional substitution.

Q: What is the primary reason to transition from MAX1090ACEI to MAX1090BCEI+?

A: The MAX1090ACEI is classified as obsolete, creating long-term supply availability risk. The MAX1090BCEI+ is an active product with ROHS3 compliance, ensuring sustained component availability and regulatory alignment.

Q: Are there packaging differences between the substitute parts?

A: All three parts use the 28-QSOP surface mount package with identical 0.154" (3.90mm) width. Mechanical compatibility is maintained across all variants.

Q: What is the difference between MAX1090ACEI+ and MAX1090BCEI+?

A: Both are active products with ROHS3 compliance. The MAX1090BCEI+ provides complete parametric documentation matching the original MAX1090ACEI specification. The MAX1090ACEI+ has limited parametric detail in available data.

Q: Are moisture sensitivity levels identical across all variants?

A: Yes. All three parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.

Q: Do all substitute parts support the same supply voltage ranges?

A: Yes. All variants operate with 5V analog supply and 2.7V to 5.5V digital supply, maintaining full compatibility with existing power distribution designs.
