MAX188CEWP Equivalent & Substitute Parts

Part Overview

The MAX188CEWP is a 12-bit Data Acquisition System (DAS) integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. This device features 8 channels, a 133 kHz sampling rate, and serial data interface capability in a 20-SOIC surface mount package. The MAX188CEWP is classified as obsolete, making identification of suitable substitute components essential for ongoing system support, design updates, and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX188CEWP is determined by strict equivalence across the following critical parameters:

• Channel Count: 8 channels (fixed requirement)
• Resolution: 12 bits (fixed requirement)
• Sampling Rate: 133 kHz (fixed requirement)
• Package Type: 20-SOIC form factor (fixed requirement)
• Mounting Type: Surface mount (fixed requirement)
• Operating Temperature Range: -40°C to 85°C (fixed requirement)
• Voltage Supply Configuration: Dual ± supply (fixed requirement)

The MAX188CEWP+ qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. The primary distinction is product status and compliance certification, with the MAX188CEWP+ classified as active and RoHS3 compliant, whereas the original MAX188CEWP is obsolete and RoHS non-compliant.

Parameter Comparison

Engineering Selection Recommendations

The MAX188CEWP+ is the direct functional equivalent of the MAX188CEWP. Selection between these parts is determined by regulatory and supply chain requirements:

Use MAX188CEWP+ when:

• RoHS3 compliance is required for new designs or production
• Active product support and availability are priorities
• Designs are being updated or refreshed
• Supply chain continuity is essential

Use MAX188CEWP when:

• Legacy system maintenance requires exact original component matching
• RoHS compliance is not a design constraint
• Existing inventory must be consumed

Both parts maintain identical electrical performance across all specified parameters: 8-channel, 12-bit resolution, 133 kHz sampling rate, dual ± supply operation, and -40°C to 85°C operating temperature range in the 20-SOIC package.

Frequently Asked Questions (FAQ)

Q: Can MAX188CEWP+ replace MAX188CEWP in existing designs?

A: Yes. The MAX188CEWP+ is electrically and mechanically equivalent. It provides identical channel count (8), resolution (12 bits), sampling rate (133 kHz), supply configuration (dual ±), operating temperature range (-40°C to 85°C), and package form factor (20-SOIC). The MAX188CEWP+ additionally supports MICROWIRE™, QSPI™, and SPI™ interfaces alongside the base serial interface.

Q: What is the primary difference between MAX188CEWP and MAX188CEWP+?

A: The MAX188CEWP+ is the active production variant with RoHS3 compliance certification. The original MAX188CEWP is obsolete and RoHS non-compliant. Both maintain identical core specifications for data acquisition functionality.

Q: Are there any package or pinout differences?

A: No. Both parts use the identical 20-SOIC (0.295", 7.50mm Width) surface mount package. Pinout and mechanical dimensions are equivalent, allowing direct PCB substitution without layout modifications.

Q: What supply voltage does the MAX188CEWP+ require?

A: The MAX188CEWP+ operates on a dual ± supply configuration specified as ±5V. The original MAX188CEWP specifies dual ± supply without explicit voltage rating in the provided data.

Q: Is the MAX188CEWP+ suitable for new product designs?

A: Yes. The MAX188CEWP+ is classified as active product status and carries RoHS3 compliance, making it appropriate for new designs requiring regulatory compliance and long-term supply availability.
