MAX170CCWE Equivalent & Substitute Parts

Part Overview

The MAX170CCWE 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 operates from dual supply voltages (5V and -12V to 15V). The device is packaged in a 16-SOIC surface-mount package.

The MAX170CCWE is classified as obsolete. Finding equivalent substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support long-term product availability for legacy systems or new designs requiring this functionality.

Substitute Part Grouping Explanation

Substitute parts for the MAX170CCWE are identified based on strict parametric equivalence. The following criteria determine substitutability:

• Resolution: 12 bits
• Sampling Rate: 125 kSPS
• Number of Inputs: 1
• Input Type: Single Ended
• Data Interface: SPI
• Architecture: SAR
• Reference Type: Internal
• Supply Voltages: 5V, -12V to 15V (both analog and digital)
• Operating Temperature: 0°C to 70°C
• Package: 16-SOIC surface mount

The MAX170DCWE+ meets all these parametric requirements and is therefore classified as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

The MAX170DCWE+ is the direct parametric equivalent for the MAX170CCWE. Both devices share identical electrical specifications, pin configurations, and package dimensions, ensuring drop-in compatibility at the circuit level.

The MAX170DCWE+ offers the following advantages:

• Active product status ensures long-term availability and continued manufacturer support
• RoHS3 compliance meets current environmental and regulatory requirements
• Tube packaging provides standard handling and storage conditions for production environments

The MAX170CCWE, being obsolete, should be replaced with the MAX170DCWE+ in new designs or when replenishing inventory for existing applications.

Frequently Asked Questions (FAQ)

Q: Can the MAX170DCWE+ be used as a direct replacement for the MAX170CCWE?

A: Yes. The MAX170DCWE+ is a parametric equivalent with identical resolution (12 bits), sampling rate (125 kSPS), input configuration (single-ended), data interface (SPI), supply voltages, operating temperature range, and 16-SOIC package. Pin-for-pin compatibility is maintained.

Q: What is the difference between the MAX170CCWE and MAX170DCWE+?

A: The primary differences are product status and compliance. The MAX170CCWE is obsolete and RoHS non-compliant, while the MAX170DCWE+ is an active product with RoHS3 compliance. Electrical and functional specifications are identical.

Q: Are there any package differences between these parts?

A: Both devices use the 16-SOIC (0.295", 7.50mm Width) surface-mount package. The MAX170DCWE+ is supplied in tube packaging, which is standard for active production parts.

Q: What supply voltages do these ADCs require?

A: Both the MAX170CCWE and MAX170DCWE+ require dual supply voltages: 5V and -12V to 15V for both analog and digital supplies.

Q: Is the MAX170DCWE+ suitable for new designs?

A: Yes. The MAX170DCWE+ is an active product with current manufacturer support and RoHS3 compliance, making it the appropriate choice for new designs requiring 12-bit, single-input SAR ADC functionality with SPI interface.
