MAX156ACWI+ Equivalent & Substitute Parts

Part Overview

The MAX156ACWI+ is an 8-bit Analog to Digital Converter (ADC) manufactured by Analog Devices Inc./Maxim Integrated, designed for data acquisition applications requiring simultaneous sampling and selectable addressing. This SAR (Successive Approximation Register) architecture device operates with 2 or 4 differential/single-ended inputs and delivers a 250 kSPS sampling rate. The part is currently in active production status with full ROHS3 compliance and unlimited moisture sensitivity rating, making it suitable for industrial and commercial applications operating between 0°C and 70°C.

Alternative components may be required due to supply constraints, design revisions, or system integration requirements while maintaining equivalent electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX156ACWI+ is determined by strict equivalence across the following critical parameters:

• Resolution: 8-bit conversion capability
• Sampling Rate: 250 kSPS minimum performance
• Input Configuration: Support for 2 or 4 inputs with differential and single-ended modes
• Data Interface: Parallel output architecture
• ADC Architecture: SAR-based conversion
• Supply Voltage Compatibility: ±5V and 5V dual supply operation
• Package Compatibility: 28-SOIC surface mount form factor
• Regulatory Compliance: ROHS3 compliance and MSL Level 1 rating

Only components meeting all specified parameters across electrical performance, supply requirements, and mechanical packaging are classified as direct substitutes. The MAX156ACWI+ represents the current production equivalent within this specification set.

Parameter Comparison

Engineering Selection Recommendations

The MAX156ACWI+ is the active production part meeting all specified electrical and mechanical requirements. Selection of this component is supported by:

• Active product status ensuring continued manufacturing and supply availability
• Full ROHS3 compliance for regulatory adherence in restricted substance applications
• MSL Level 1 rating providing unlimited shelf life without moisture sensitivity constraints
• Established design validation across the specified operating temperature range (0°C ~ 70°C)

No alternative substitutes meeting identical parameter specifications are currently documented. Component selection should be based on application-specific supply requirements and design timeline constraints.

Frequently Asked Questions (FAQ)

Q: What determines if a part can substitute for the MAX156ACWI+?

A: Direct substitution requires identical specifications across resolution (8-bit), sampling rate (250 kSPS), input configuration (2 or 4 inputs, differential/single-ended), data interface (parallel), architecture (SAR), supply voltages (±5V, 5V), package type (28-SOIC), and compliance ratings (ROHS3, MSL Level 1).

Q: Is the MAX156ACWI+ suitable for applications requiring higher sampling rates?

A: The MAX156ACWI+ operates at 250 kSPS. Applications requiring higher sampling rates require components with different specifications and are outside the scope of this equivalency document.

Q: Can the MAX156ACWI+ be used in surface mount and through-hole designs?

A: The MAX156ACWI+ is specified for surface mount applications only, utilizing the 28-SOIC package format with 0.295" width (7.50mm). Through-hole mounting requires alternative package configurations not covered by this part number.

Q: What is the significance of the 4:1 S/H:ADC ratio?

A: The 4:1 Sample-and-Hold to ADC ratio indicates the simultaneous sampling capability across the 2 or 4 input channels, enabling parallel data acquisition with selectable address configuration as specified in the features set.

Q: Are there temperature-rated variants of the MAX156ACWI+?

A: The MAX156ACWI+ is specified for 0°C ~ 70°C commercial operating temperature range. Extended temperature variants require different part numbers and are not substitutes for this specification.
