MAX188DCPP Equivalent & Substitute Parts

Part Overview

The MAX188DCPP is a 12-bit Analog-to-Digital Converter (ADC) manufactured by Analog Devices Inc./Maxim Integrated, designed for data acquisition applications requiring SAR (Successive Approximation Register) architecture. The device supports 4 or 8 differential and single-ended inputs with a sampling rate of 133 kSPS and operates on dual ±5V or single 5V supply rails. The MAX188DCPP is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production support.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX188DCPP is determined by strict alignment of the following critical parameters:

• Resolution: 12 bits (exact match required)
• Sampling Rate: 133 kSPS (exact match required)
• Number of Channels: 8 channels (maximum configuration)
• Input Configuration: Differential and single-ended support
• Data Interface: SPI-compatible serial protocols (SPI, QSPI, MICROWIRE)
• Supply Voltage: Dual ±5V or single 5V operation
• Package: 20-DIP form factor with 0.300" (7.62mm) pitch
• Mounting: Through-hole technology

The MAX188DCPP+ qualifies as a direct substitute based on identical electrical specifications, matching package geometry, and compatible serial interface protocols. The primary distinction is product status and compliance certification.

Engineering Selection Recommendations

The MAX188DCPP+ is the direct equivalent for the obsolete MAX188DCPP. Selection of the MAX188DCPP+ is justified by:

• Product Availability: The MAX188DCPP+ maintains active production status, ensuring long-term supply chain reliability compared to the obsolete MAX188DCPP.
• Regulatory Compliance: The MAX188DCPP+ achieves ROHS3 compliance, meeting current environmental and material restriction requirements. The original MAX188DCPP is RoHS non-compliant.
• Electrical Equivalence: Both devices share identical 12-bit resolution, 133 kSPS sampling rate, 20-DIP package geometry, and dual ±5V supply specifications.
• Interface Compatibility: The MAX188DCPP+ supports SPI alongside MICROWIRE and QSPI protocols, maintaining backward compatibility with existing SPI-based designs.
• Certification Alignment: Both parts maintain identical REACH and ECCN classifications (REACH Unaffected, EAR99).

Frequently Asked Questions (FAQ)

Q: Can the MAX188DCPP+ directly replace the MAX188DCPP in existing designs?

A: Yes. Both devices share identical 12-bit resolution, 133 kSPS sampling rate, 20-DIP package footprint, and dual ±5V supply specifications. The MAX188DCPP+ supports SPI alongside additional serial protocols (MICROWIRE, QSPI), ensuring full backward compatibility.

Q: What is the primary reason to transition from MAX188DCPP to MAX188DCPP+?

A: The MAX188DCPP is classified as obsolete, creating supply chain risk. The MAX188DCPP+ is in active production and achieves ROHS3 compliance, meeting current regulatory requirements.

Q: Are there package or mounting differences between these parts?

A: No. Both devices use identical 20-DIP (0.300", 7.62mm) through-hole packaging. PCB layouts and mechanical mounting are fully compatible.

Q: Does the MAX188DCPP+ support the same input configurations?

A: Yes. Both devices support differential and single-ended input configurations with 8-channel maximum capacity and identical operating temperature ranges (0°C to 70°C).

Q: What supply voltage options are available for the MAX188DCPP+?

A: The MAX188DCPP+ operates on dual ±5V supply rails, matching the original MAX188DCPP specifications for analog and digital supply voltages.
