MAX188ACAP+ Equivalent & Substitute Parts Reference

Part Overview

The MAX188ACAP+ is a 12-bit analog-to-digital converter (ADC) manufactured by Analog Devices Inc./Maxim Integrated, designed for data acquisition applications requiring serial communication interfaces. This device features 8 input channels, a 133 kHz sampling rate, and dual ±5V supply operation in a 20-pin SSOP surface mount package.

The MAX188ACAP+ is classified as obsolete. For applications currently using this component, identifying equivalent substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support long-term product availability.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MAX188ACAP+ must satisfy the following critical parameters to ensure functional and mechanical compatibility:

• Resolution (Bits): 12 bits
• Number of Channels: 8 channels
• Sampling Rate (Per Second): 133 kHz minimum
• Data Interface: Support for MICROWIRE™, QSPI™, Serial, or SPI™ protocols
• Voltage Supply Source: Dual ± supply configuration
• Voltage - Supply: ±5V operation
• Package / Case: 20-SSOP form factor
• Mounting Type: Surface Mount
• Operating Temperature Range: 0°C to 70°C minimum

Substitution is valid only when all electrical parameters and the physical package specification are matched or exceeded. Interface protocol compatibility and supply voltage requirements are non-negotiable for direct replacement.

Parameter Comparison

Engineering Selection Recommendations

The MAX188ACAP+ is ROHS3 compliant and carries MSL 1 rating, indicating minimal moisture sensitivity and full compliance with current environmental regulations. When selecting substitute components, maintain equivalence across all specified electrical parameters: 12-bit resolution, 8-channel configuration, 133 kHz sampling rate, dual ±5V supply, and serial communication protocol support.

The 20-SSOP package specification is fixed and non-negotiable for PCB layout compatibility. Surface mount mounting type must be preserved. Operating temperature range of 0°C to 70°C establishes the baseline thermal requirement for substitute selection.

Compliance certifications (ROHS3, MSL 1) should be verified for any substitute part to ensure regulatory alignment with the original component specification.

Frequently Asked Questions (FAQ)

Q: What makes a part a valid substitute for the MAX188ACAP+?

A: A valid substitute must match all critical electrical parameters: 12-bit resolution, 8 channels, 133 kHz sampling rate, dual ±5V supply, and support for MICROWIRE™, QSPI™, Serial, or SPI™ data interfaces. The package must be 20-SSOP surface mount, and operating temperature range must cover 0°C to 70°C.

Q: Can I use a different package type as a substitute?

A: No. The 20-SSOP package specification is a fixed requirement for PCB layout and assembly compatibility. Package changes require circuit board redesign and are not considered direct substitution.

Q: Are there any protocol compatibility considerations?

A: The MAX188ACAP+ supports multiple serial protocols: MICROWIRE™, QSPI™, Serial, and SPI™. Substitute parts must support at least one of these protocols. Verify that your application uses a supported protocol before substitution.

Q: What is the significance of the ROHS3 and MSL 1 ratings?

A: ROHS3 compliance indicates the part meets current environmental and hazardous substance restrictions. MSL 1 (Unlimited) means the component has minimal moisture sensitivity and requires no special storage or handling precautions. These certifications should be maintained in substitute parts for regulatory consistency.

Q: Why is the MAX188ACAP+ listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. Substitute parts ensure design continuity and supply chain stability for applications currently using this component.
