MAX192ACWP Equivalent & Substitute Parts

Part Overview

The MAX192ACWP is a 10-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 MAX192ACWP is classified as obsolete, making identification of compatible substitute parts essential for ongoing system support, design updates, and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX192ACWP is determined by strict equivalence across the following critical parameters:

• Number of Channels: 8 channels (fixed requirement)
• Resolution: 10 bits (fixed requirement)
• Sampling Rate: 133 kHz (fixed requirement)
• Package / Case: 20-SOIC form factor (fixed requirement)
• Mounting Type: Surface Mount (fixed requirement)
• Operating Temperature Range: 0°C to 70°C (fixed requirement)
• Voltage Supply Source: Single Supply (fixed requirement)

The MAX192ACWP+ meets all these criteria and is identified as a direct substitute. The primary distinction between the main part and its substitute is product status and compliance certification, not functional or electrical parameters.

Parameter Comparison

Engineering Selection Recommendations

The MAX192ACWP+ is the direct substitute for the obsolete MAX192ACWP. Both devices share identical functional specifications across all critical parameters: 8-channel configuration, 10-bit resolution, 133 kHz sampling rate, single supply operation, and 20-SOIC packaging.

The MAX192ACWP+ offers two significant advantages for new designs and system updates:

• Active Product Status: The MAX192ACWP+ is currently in active production, ensuring long-term availability and supply chain stability.
• RoHS3 Compliance: The MAX192ACWP+ meets ROHS3 compliance requirements, whereas the original MAX192ACWP is RoHS non-compliant. This compliance status is critical for applications subject to environmental regulations and industry standards.

Both devices maintain identical moisture sensitivity levels and REACH status. The MAX192ACWP+ supports expanded data interface options (MICROWIRE™, QSPI™, SPI™) in addition to the serial interface, providing enhanced flexibility for system integration without compromising backward compatibility.

Frequently Asked Questions (FAQ)

Q: Can the MAX192ACWP+ be used as a direct replacement for the MAX192ACWP?

A: Yes. The MAX192ACWP+ is electrically and mechanically equivalent to the MAX192ACWP across all functional parameters: 8 channels, 10-bit resolution, 133 kHz sampling rate, single supply operation, and 20-SOIC package. Both devices operate within the same temperature range (0°C to 70°C) and share identical moisture sensitivity levels.

Q: What is the primary reason to transition from MAX192ACWP to MAX192ACWP+?

A: The MAX192ACWP is obsolete, while the MAX192ACWP+ is in active production. Additionally, the MAX192ACWP+ is ROHS3 compliant, whereas the original part is RoHS non-compliant. For new designs and system updates, the MAX192ACWP+ ensures regulatory compliance and supply chain continuity.

Q: Are there any package or pinout differences between these parts?

A: No. Both the MAX192ACWP and MAX192ACWP+ use the identical 20-SOIC package with 0.295" width (7.50mm). Pinout and mechanical dimensions are equivalent, allowing direct board-level substitution.

Q: Does the MAX192ACWP+ support the same data interfaces as the MAX192ACWP?

A: The MAX192ACWP+ supports serial interface operation identical to the MAX192ACWP, plus additional interface options (MICROWIRE™, QSPI™, SPI™). Existing designs using serial interface operation require no modification.

Q: Are there any supply voltage differences?

A: Both devices operate as single supply devices. The MAX192ACWP+ specifies ±5V supply voltage. Designs using the MAX192ACWP should verify supply voltage compatibility with the MAX192ACWP+ before implementation.

Q: What is the moisture sensitivity level for both parts?

A: Both the MAX192ACWP and MAX192ACWP+ have a Moisture Sensitivity Level (MSL) of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage and handling.
