MAX1290ACEI Equivalent & Substitute Parts

Part Overview

The MAX1290ACEI is a 12-bit Successive Approximation Register (SAR) analog-to-digital converter manufactured by Analog Devices Inc./Maxim Integrated. This device features 4 or 8 pseudo-differential and single-ended inputs with a 400 kSPS sampling rate and parallel data interface. The part is currently classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity.

Substitute Part Grouping Explanation

Substitute parts for the MAX1290ACEI are identified based on strict parameter equivalence across the following criteria:

Core Electrical Parameters:

• Resolution: 12 bits
• Sampling Rate: 400 kSPS
• Number of Inputs: 4, 8
• Input Type: Pseudo-Differential, Single Ended
• Data Interface: Parallel
• Architecture: SAR
• Reference Type: External, Internal
• Analog Supply: 5V
• Digital Supply: 2.7V ~ 5.5V
• Operating Temperature: 0°C ~ 70°C

Mechanical Parameters:

• Package: 28-SSOP (0.154", 3.90mm Width)
• Mounting Type: Surface Mount

All substitute parts listed maintain identical electrical and mechanical specifications to the main part. Substitution is valid where these parameters match completely.

Engineering Selection Recommendations

MAX1290ACEI+ (Direct Substitute): This part is the direct successor to the MAX1290ACEI with identical electrical and mechanical specifications. It carries active product status and ROHS3 compliance, making it the preferred choice for new designs and production continuity. The packaging format (Tube) differs from the original, but electrical compatibility is complete.

MAX1290BCEI+ (Parametric Equivalent): This part maintains all electrical and mechanical parameters of the MAX1290ACEI while offering active product status and ROHS3 compliance. It represents an alternative within the MAX1290 product line with equivalent performance characteristics.

MAX1262BCEI+ (Parametric Equivalent): This part is a parametric equivalent from the MAX1262 product line, maintaining all specified electrical and mechanical parameters. It is active and ROHS3 compliant. Selection of this part should be based on design requirements and supply chain considerations, as it represents a different base product number.

All three substitute parts are suitable for applications requiring the electrical and mechanical specifications of the MAX1290ACEI. The transition from obsolete to active product status and ROHS3 compliance represents a regulatory and supply chain advantage.

Frequently Asked Questions (FAQ)

Q: Can MAX1290ACEI+ be used as a direct replacement for MAX1290ACEI? A: Yes. MAX1290ACEI+ maintains identical electrical specifications (12-bit resolution, 400 kSPS sampling rate, 4/8 inputs, parallel interface, 28-SSOP package) and is electrically compatible. The primary differences are product status (active vs. obsolete) and RoHS compliance.

Q: What is the difference between MAX1290BCEI+ and MAX1290ACEI+? A: Both parts share identical electrical and mechanical specifications. The difference lies in the product designation within the MAX1290 family. Both are active and ROHS3 compliant.

Q: Is MAX1262BCEI+ compatible with designs using MAX1290ACEI? A: Yes, from an electrical and mechanical standpoint. MAX1262BCEI+ maintains all specified parameters: 12-bit resolution, 400 kSPS sampling rate, 4/8 inputs, pseudo-differential and single-ended input types, parallel data interface, and 28-SSOP package. The base product number differs (MAX1262 vs. MAX1290), but functional equivalence is maintained.

Q: Are there packaging differences between the substitute parts? A: The MAX1290ACEI was supplied in standard packaging. MAX1290ACEI+, MAX1262BCEI+, and MAX1290BCEI+ are supplied in Tube packaging. The physical package (28-SSOP) and mounting type (Surface Mount) remain identical.

Q: Which substitute part should be selected for new designs? A: Selection should be based on supply chain availability, cost considerations, and design timeline. All three substitute parts are electrically and mechanically equivalent. MAX1290ACEI+ and MAX1290BCEI+ maintain the MAX1290 product line designation, while MAX1262BCEI+ offers an alternative from the MAX1262 line with identical specifications.

Q: Are all substitute parts RoHS compliant? A: Yes. MAX1290ACEI+, MAX1262BCEI+, and MAX1290BCEI+ are all ROHS3 compliant, whereas the original MAX1290ACEI is RoHS non-compliant.
