MAX170DCWE Equivalent & Substitute Parts

Part Overview

The MAX170DCWE is a 12-bit Analog-to-Digital Converter (ADC) manufactured by Analog Devices Inc./Maxim Integrated, designed for single-ended input data acquisition applications. It features a Successive Approximation Register (SAR) architecture with a 125 kSPS sampling rate and SPI digital interface, housed in a 16-SOIC surface mount package.

The MAX170DCWE is classified as an obsolete product. Finding equivalent or substitute parts is necessary to support legacy system maintenance, design updates, or when original inventory becomes unavailable. The primary substitute identified maintains identical electrical and mechanical specifications while offering improved compliance status and active product support.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX170DCWE is determined by strict equivalence across the following critical parameters:

• 12-bit resolution
• 125 kSPS sampling rate
• Single-ended input configuration
• SPI digital interface
• SAR architecture with internal reference
• Dual supply voltage range (5V, -12V ~ 15V)
• 16-SOIC surface mount package
• Operating temperature range 0°C ~ 70°C

The MAX170DCWE+ meets all these criteria and is therefore a direct functional equivalent. The primary distinction between these parts is product status and compliance certification, not electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

The MAX170DCWE+ is a direct substitute for the MAX170DCWE based on identical electrical specifications and mechanical compatibility. Selection between these parts should be based on the following factors:

Product Status: The MAX170DCWE is obsolete and no longer supported by the manufacturer. The MAX170DCWE+ is an active product with ongoing manufacturer support and availability.

Compliance Requirements: The MAX170DCWE+ meets RoHS3 compliance standards, whereas the MAX170DCWE is RoHS non-compliant. For applications subject to RoHS directives or environmental regulations, the MAX170DCWE+ is the appropriate choice.

Supply Chain Considerations: The MAX170DCWE+ is available in tube packaging format with active inventory. The MAX170DCWE remains available in limited quantities as legacy stock.

Both parts share identical electrical performance characteristics, pinout, and package dimensions, ensuring direct compatibility in existing circuit designs without modification.

Frequently Asked Questions (FAQ)

Q: Can the MAX170DCWE+ be used as a direct replacement for the MAX170DCWE in existing designs?

A: Yes. The MAX170DCWE+ is electrically and mechanically identical to the MAX170DCWE. No circuit modifications or PCB changes are required for substitution.

Q: What is the difference between MAX170DCWE and MAX170DCWE+?
