Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX188CCPP is determined by strict equivalence across the following critical parameters:

• Resolution: 12-bit ADC
• Sampling Rate: 133 kSPS minimum
• Input Configuration: Support for 4 or 8 channels with differential and single-ended capability
• Data Interface: SPI-compatible serial communication
• Architecture: SAR-based conversion
• Supply Voltage: ±5V or 5V operation
• Package: 20-DIP form factor with 0.300" (7.62mm) pitch
• Mounting: Through-hole technology

The MAX188CCPP+ meets all substitution criteria as a direct equivalent, maintaining identical electrical specifications and physical packaging while offering improved compliance status.

Parameter Comparison

Engineering Selection Recommendations

The MAX188CCPP+ is a direct functional equivalent to the MAX188CCPP. Both devices share identical core specifications: 12-bit resolution, 133 kSPS sampling rate, SAR architecture, and 20-DIP through-hole packaging. The primary distinction is compliance status: the MAX188CCPP+ achieves ROHS3 compliance, whereas the original MAX188CCPP is RoHS non-compliant.

For new designs or systems requiring regulatory compliance with modern environmental standards, the MAX188CCPP+ is the appropriate selection. For legacy system maintenance where RoHS compliance is not a requirement, either part may be used interchangeably from an electrical and mechanical standpoint.

Both parts are classified as obsolete. Procurement should account for limited availability and consider long-term supply chain planning.

Frequently Asked Questions (FAQ)

Q: Can MAX188CCPP+ replace MAX188CCPP in existing designs?

A: Yes. The MAX188CCPP+ is electrically and mechanically equivalent. Both devices operate at 12-bit resolution, 133 kSPS sampling rate, support identical input configurations, and use the same 20-DIP package. Direct substitution is possible without circuit modification.

Q: What is the difference between MAX188CCPP and MAX188CCPP+?

A: The primary difference is RoHS compliance status. MAX188CCPP+ is ROHS3 compliant, while MAX188CCPP is RoHS non-compliant. Both devices have identical electrical specifications and packaging.

Q: Are there differences in data interface compatibility?

A: The MAX188CCPP specifies SPI interface. The MAX188CCPP+ supports MICROWIRE™, QSPI™, Serial, and SPI™ protocols. Both are SPI-compatible, ensuring protocol compatibility in existing applications.

Q: What supply voltage options are available?

A: MAX188CCPP supports ±5V or 5V operation for both analog and digital supplies. MAX188CCPP+ operates on ±5V dual supply. Verify your system's supply configuration before substitution.

Q: Are both parts available in the same package?

A: Yes. Both MAX188CCPP and MAX188CCPP+ use 20-DIP (0.300", 7.62mm) through-hole packaging. Physical board layout compatibility is maintained.

Q: Why are both parts classified as obsolete?

A: Both MAX188CCPP and MAX188CCPP+ are end-of-life products from Analog Devices Inc./Maxim Integrated. Availability is limited to existing inventory. For new designs, consult the manufacturer for current-generation ADC alternatives.
