MAX1270ACAI Equivalent & Substitute Parts

Part Overview

The MAX1270ACAI is a 12-bit Data Acquisition System (DAS) with 8 channels, 110k sampling rate, and serial interface capability. Manufactured by Analog Devices Inc./Maxim Integrated, this component operates as a single-supply device in a 28-SSOP surface mount package. The part is currently classified as obsolete, making identification of suitable substitutes essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX1270ACAI is determined by strict equivalence across the following critical parameters:

• Number of Channels: 8 channels
• Resolution: 12 bits
• Sampling Rate: 110k samples per second
• Data Interface: Serial capability
• Voltage Supply Source: Single Supply
• Operating Temperature Range: 0°C to 70°C
• Package Type: 28-SSOP (0.209", 5.30mm Width)
• Mounting Type: Surface Mount

The MAX1270ACAI+ qualifies as a direct substitute based on matching all core electrical and mechanical specifications. The primary distinction lies in product status and compliance certifications rather than functional parameters.

Parameter Comparison

Engineering Selection Recommendations

The MAX1270ACAI+ is the direct functional equivalent of the MAX1270ACAI. Selection between these parts should be based on the following criteria:

For new designs and systems requiring regulatory compliance, the MAX1270ACAI+ is the appropriate choice. This part carries Active product status and ROHS3 compliance certification, aligning with current environmental and regulatory standards.

For legacy system maintenance where existing inventory of MAX1270ACAI components is available, continued use of the original part is acceptable provided that RoHS non-compliance does not conflict with system-level requirements or end-market regulations.

Both parts share identical core functionality: 8-channel, 12-bit resolution, 110k sampling rate operation in a 28-SSOP package. The MAX1270ACAI+ offers expanded serial interface options (MICROWIRE™, QSPI™, SPI™) in addition to standard serial capability, with specified supply voltage range of 4.75V to 5.25V.

Frequently Asked Questions (FAQ)

Q: Can MAX1270ACAI+ be used as a direct replacement for MAX1270ACAI in existing designs?

A: Yes. Both parts maintain identical channel count (8), resolution (12 bits), sampling rate (110k), operating temperature range (0°C to 70°C), and 28-SSOP package dimensions. The MAX1270ACAI+ is pin-compatible and functionally equivalent.

Q: What is the primary difference between MAX1270ACAI and MAX1270ACAI+?

A: The MAX1270ACAI+ is an active product with ROHS3 compliance, while the MAX1270ACAI is obsolete and RoHS non-compliant. The MAX1270ACAI+ also specifies supply voltage range (4.75V to 5.25V) and offers additional serial interface protocols (MICROWIRE™, QSPI™, SPI™).

Q: Are there any package or mounting differences between these parts?

A: No. Both parts use identical 28-SSOP surface mount packaging with 0.209" width (5.30mm). PCB footprints and assembly processes remain unchanged.

Q: What does the "+" designation indicate in MAX1270ACAI+?

A: The "+" suffix indicates an updated version of the base MAX1270 product line. In this case, it denotes the active, compliant variant with expanded interface capabilities.

Q: Is the MAX1270ACAI+ available in different packaging options?

A: The MAX1270ACAI+ is supplied in Tube packaging. The original MAX1270ACAI packaging specification was not provided in the technical data.

Q: Are moisture sensitivity levels identical between both parts?

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