Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX196ACWI is determined by strict equivalence across the following critical parameters:

• Channel Count: 6 channels (fixed requirement)
• Resolution: 12 bits (fixed requirement)
• Sampling Rate: 100 kHz (fixed requirement)
• Data Interface: Parallel (fixed requirement)
• Package: 28-SOIC form factor (fixed requirement)
• Mounting Type: Surface Mount (fixed requirement)
• Supply Configuration: Single Supply (fixed requirement)

The MAX196ACWI+ qualifies as a direct substitute based on identical electrical specifications and mechanical compatibility. The primary distinction is product status: the original MAX196ACWI is obsolete, while the MAX196ACWI+ remains active in production.

Parameter Comparison

Engineering Selection Recommendations

The MAX196ACWI+ is the direct functional equivalent of the MAX196ACWI. Both components share identical electrical and mechanical specifications across all critical parameters: 6-channel configuration, 12-bit resolution, 100 kHz sampling rate, parallel data interface, and 28-SOIC package footprint.

Selection of the MAX196ACWI+ is supported by the following factors:

• Product Availability: The MAX196ACWI+ maintains active production status, ensuring supply chain continuity and availability for new designs and production runs.
• Regulatory Compliance: The MAX196ACWI+ achieves ROHS3 compliance, whereas the original MAX196ACWI is non-compliant. For applications subject to RoHS directives, the MAX196ACWI+ is the required choice.
• Pin and Package Compatibility: Both components utilize the 28-SOIC package with identical pinout and mechanical dimensions, enabling direct board-level substitution without layout modifications.
• Electrical Equivalence: Functional performance, operating temperature range, and supply voltage specifications are identical between the two parts.

Frequently Asked Questions (FAQ)

Q: Can the MAX196ACWI+ be used as a direct replacement for the MAX196ACWI in existing designs?

A: Yes. The MAX196ACWI+ is electrically and mechanically equivalent to the MAX196ACWI.
