MAX188CEPP Equivalent & Substitute Parts

Part Overview

The MAX188CEPP is a 12-bit Analog-to-Digital Converter (ADC) manufactured by Analog Devices Inc./Maxim Integrated, designed for data acquisition applications requiring moderate sampling rates and flexible input configurations. This component features a Successive Approximation Register (SAR) architecture with support for both differential and single-ended inputs, operating from dual ±5V or single 5V supply rails.

The MAX188CEPP is classified as obsolete, which necessitates identification of functionally equivalent alternatives for new designs or ongoing production requirements. The primary substitute maintains core electrical specifications while offering improved product status and compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX188CEPP is based on strict equivalence across the following critical parameters:

• Resolution and Sampling Rate: 12-bit resolution at 133 kSPS sampling rate
• Input Configuration: Support for 4 or 8 input channels with differential and single-ended input types
• Data Interface Protocol: SPI-compatible serial communication (including MICROWIRE™ and QSPI™ variants)
• Supply Voltage Compatibility: Dual ±5V or single 5V operation
• Package and Pinout: 20-DIP form factor with identical pin assignments
• Operating Temperature Range: -40°C to 85°C industrial temperature specification
• Mounting Technology: Through-hole mounting on printed circuit boards

The MAX188CEPP+ qualifies as a direct substitute based on full compliance with all specified electrical and mechanical parameters.

Engineering Selection Recommendations

The MAX188CEPP+ is the appropriate substitute for the obsolete MAX188CEPP based on the following engineering criteria:

Product Status: The MAX188CEPP+ maintains active product status with ongoing manufacturer support, ensuring continued availability and technical documentation access. The MAX188CEPP is classified as obsolete, creating supply chain risk and limiting access to design resources.

Regulatory Compliance: The MAX188CEPP+ achieves ROHS3 compliance, meeting current environmental and hazardous substance restrictions applicable to electronic components in regulated markets. The original MAX188CEPP does not meet these requirements.

Electrical Equivalence: Both components share identical core specifications across resolution, sampling rate, input configuration, data interface protocols, operating temperature range, and supply voltage requirements. The MAX188CEPP+ supports an expanded set of serial interface protocols (MICROWIRE™, QSPI™, Serial, SPI™) while maintaining full SPI compatibility.

Physical Compatibility: Identical 20-DIP package geometry and through-hole mounting technology ensure direct board-level substitution without layout modifications.

Certification Alignment: Both components maintain identical REACH and ECCN classifications, with equivalent moisture sensitivity ratings.

Frequently Asked Questions (FAQ)

Q: Can the MAX188CEPP+ be used as a direct replacement for the MAX188CEPP in existing designs?

A: Yes. The MAX188CEPP+ maintains identical pinout, package geometry, electrical specifications, and operating parameters. No circuit modifications are required for substitution.

Q: What is the difference between the data interface protocols listed for the MAX188CEPP+?

A: The MAX188CEPP+ supports multiple serial communication standards: SPI (Serial Peripheral Interface), MICROWIRE™, QSPI™ (Queued Serial Peripheral Interface), and generic Serial protocols. All are compatible with standard SPI implementations. The original MAX188CEPP specifies SPI only.

Q: Does the MAX188CEPP+ support the same input channel configurations as the MAX188CEPP?

A: The MAX188CEPP+ is specified with 8 input channels. The original MAX188CEPP supports both 4 and 8 input configurations. Both versions support differential and single-ended input types. Verify your application requires only the 8-channel configuration.

Q: What is the significance of the RoHS3 compliance difference?

A: ROHS3 compliance indicates the MAX188CEPP+ meets current Restriction of Hazardous Substances directives applicable to electronic components. The non-compliant MAX188CEPP may face restrictions in certain markets or applications with regulatory requirements.

Q: Are there any supply voltage differences between these components?

A: The MAX188CEPP supports both ±5V dual supply and single 5V supply operation. The MAX188CEPP+ is specified for ±5V dual supply. Verify your application uses dual ±5V supply configuration.

Q: Is the packaging format identical between both parts?

A: Yes. Both components use 20-DIP (0.300", 7.62mm) through-hole packaging with identical pin assignments and mechanical dimensions.
