MAX1270BCAI Equivalent & Substitute Parts

Part Overview

The MAX1270BCAI 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 analog-to-digital converter in a 28-SSOP surface mount package.

The MAX1270BCAI is classified as obsolete. Locating equivalent or substitute parts becomes necessary when original inventory is depleted or when design requirements mandate components with active product status and current compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX1270BCAI is determined by strict equivalence across the following electrical and mechanical parameters:

• Number of Channels: 8 channels
• Resolution: 12 bits
• Sampling Rate: 110k samples per second
• Data Interface: Serial protocol compatibility
• Voltage Supply Source: Single supply operation
• Operating Temperature Range: 0°C to 70°C
• Package / Case: 28-SSOP form factor with 0.209" width (5.30mm)
• Mounting Type: Surface mount configuration

The MAX1270BCAI+ qualifies as a direct substitute based on matching all core electrical specifications and identical package geometry. The primary distinction is product status and compliance certification level.

Parameter Comparison

Engineering Selection Recommendations

The MAX1270BCAI+ serves as the direct substitute for the MAX1270BCAI. Both components share identical electrical specifications, channel count, resolution, sampling rate, and package geometry, ensuring pin-for-pin compatibility and functional equivalence in circuit applications.

The MAX1270BCAI+ offers two significant advantages over the obsolete MAX1270BCAI:

1. Active product status ensures ongoing availability and manufacturing support from Analog Devices Inc./Maxim Integrated.
2. ROHS3 compliance certification meets current environmental and regulatory requirements, whereas the MAX1270BCAI carries RoHS non-compliant status.

Selection of the MAX1270BCAI+ is appropriate for new designs, production restocking, and applications requiring current compliance certifications. The identical package footprint and electrical performance enable direct substitution without circuit redesign.

Frequently Asked Questions (FAQ)

Q: Are the MAX1270BCAI and MAX1270BCAI+ pin-compatible?

A: Yes. Both components use the 28-SSOP package with identical pin assignments and electrical specifications. Direct substitution is possible without PCB modification.

Q: What is the primary difference between these two parts?

A: The MAX1270BCAI is obsolete with RoHS non-compliant status. The MAX1270BCAI+ is an active product with ROHS3 compliance certification. Electrical performance and package geometry are identical.

Q: Can the MAX1270BCAI+ be used in existing designs originally specified for the MAX1270BCAI?

A: Yes. The MAX1270BCAI+ maintains full functional and electrical equivalence. No circuit modifications are required for substitution.

Q: What data interface protocols does the MAX1270BCAI+ support?

A: The MAX1270BCAI+ supports MICROWIRE™, QSPI™, Serial, and SPI™ protocols. The original MAX1270BCAI supports Serial interface. Applications using serial communication remain fully compatible.

Q: Are there supply voltage differences between these parts?

A: Both components operate as single-supply devices. The MAX1270BCAI+ specifies a supply voltage range of 4.75V to 5.25V. Both maintain identical operating temperature range of 0°C to 70°C.

Q: What is the moisture sensitivity level for these components?

A: Both the MAX1270BCAI and MAX1270BCAI+ carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.
