Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX188ACAP is determined by strict equivalence across the following critical parameters:

• Channel Count: 8 channels (fixed requirement)
• Resolution: 12 bits (fixed requirement)
• Sampling Rate: 133k samples per second (fixed requirement)
• Package: 20-SSOP form factor with identical pin pitch and dimensions
• Data Interface: Serial protocol compatibility (MICROWIRE™, QSPI™, SPI™ acceptable as serial variants)
• Voltage Supply Architecture: Dual ± supply configuration
• Operating Temperature Range: 0°C to 70°C minimum coverage
• Mounting Technology: Surface mount only

The MAX188ACAP+ qualifies as a direct substitute based on matching all electrical and mechanical parameters while offering improved compliance status.

Parameter Comparison

Engineering Selection Recommendations

The MAX188ACAP+ serves as the direct equivalent for MAX188ACAP applications. Both parts maintain identical electrical specifications across channel count, resolution, sampling rate, and operating temperature range. The primary distinction is regulatory compliance: MAX188ACAP+ achieves ROHS3 compliance, whereas the original MAX188ACAP is RoHS non-compliant. For new designs or systems requiring RoHS compliance, MAX188ACAP+ is the appropriate selection. For legacy system maintenance where RoHS compliance is not mandated, either part satisfies functional requirements. Both components are classified as obsolete; long-term availability should be confirmed with authorized distributors prior to procurement decisions.

Frequently Asked Questions (FAQ)

Q: Can MAX188ACAP+ replace MAX188ACAP in existing designs? A: Yes. Both parts are electrically and mechanically identical across all functional parameters. The 20-SSOP package pinout and signal timing are equivalent, enabling direct substitution on PCBs designed for MAX188ACAP.

Q: What is the difference between the serial interfaces listed for MAX188ACAP+? A: MAX188ACAP+ supports MICROWIRE™, QSPI™, Serial, and SPI™ protocols. These are serial communication variants compatible with the same 20-SSOP pinout. The original MAX188ACAP specification lists "Serial" generically; MAX188ACAP+ provides explicit protocol options.

Q: Are there packaging differences between these parts? A: No. Both MAX188ACAP and MAX188ACAP+ use identical 20-SSOP packaging with 0.209" width and 5.30mm dimensions. Supplier device packages are equivalent.

Q: Why is RoHS compliance different between the two parts? A: MAX188ACAP predates RoHS3 requirements and is non-compliant. MAX188ACAP+ was manufactured to meet ROHS3 standards. For applications subject to RoHS regulations, MAX188ACAP+ is the required selection.

Q: Are both parts still in production? A: Both MAX188ACAP and MAX188ACAP+ are classified as obsolete. Availability is limited to existing inventory from authorized distributors. Verify stock status and lead times before finalizing procurement.

Q: What is the moisture sensitivity level, and does it affect handling? A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard handling procedures for surface mount components apply.
