Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX1270BEAI is determined by strict equivalence across the following critical parameters:

• Number of Channels: 8 channels (fixed requirement)
• Resolution: 12 bits (fixed requirement)
• Sampling Rate: 110k samples per second (fixed requirement)
• Package Type: 28-SSOP form factor (fixed requirement)
• Mounting Type: Surface Mount (fixed requirement)
• Operating Temperature Range: -40°C to 85°C (fixed requirement)
• Voltage Supply Configuration: Single Supply (fixed requirement)

The MAX1270BEAI+ meets all these criteria and is manufactured by the same supplier (Analog Devices Inc./Maxim Integrated) under the same base product number (MAX1270). The primary distinction is product status and compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The MAX1270BEAI+ is the direct active equivalent for the obsolete MAX1270BEAI. Both components share identical electrical specifications across all critical parameters: 8-channel configuration, 12-bit resolution, 110k sampling rate, serial interface capability, single supply operation, and identical package geometry.

The MAX1270BEAI+ offers improved compliance status, meeting ROHS3 requirements compared to the non-compliant status of the original part. This makes the MAX1270BEAI+ the appropriate selection for new designs and procurement where component availability and regulatory compliance are required.

Frequently Asked Questions (FAQ)

Q: Can MAX1270BEAI+ directly replace MAX1270BEAI in existing designs?

A: Yes. Both parts maintain identical channel count (8), resolution (12 bits), sampling rate (110k), package type (28-SSOP), and operating temperature range (-40°C to 85°C). Pin-to-pin compatibility is maintained.

Q: What is the difference in data interface between the two parts?

A: The MAX1270BEAI specifies Serial interface only. The MAX1270BEAI+ supports multiple serial protocols: MICROWIRE™, QSPI™, Serial, and SPI™. This expanded interface support does not affect compatibility with designs using standard serial communication.

Q: Are there packaging differences between MAX1270BEAI and MAX1270BEAI+?

A: No. Both parts use identical 28-SSOP surface mount packaging with 0.209" width (5.30mm). Footprint and mounting requirements are identical.

Q: What is the significance of the RoHS compliance difference?

A: The MAX1270BEAI is RoHS non-compliant, while MAX1270BEAI+ is ROHS3 compliant. For applications subject to RoHS regulations or customer requirements, the MAX1270BEAI+ is the required selection.

Q: Are moisture sensitivity levels the same?

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