ADC10738CIWM Equivalent & Substitute Parts

Part Overview

The ADC10738CIWM is a 10-bit Analog to Digital Converter (ADC) manufactured by Texas Instruments, designed for data acquisition applications requiring 8-channel input capability with SAR (Successive Approximation Register) architecture. The device operates at a 74 kHz sampling rate and supports multiple input configurations including differential, pseudo-differential, and single-ended modes via SPI interface.

The ADC10738CIWM carries an Obsolete product status, making identification of compatible alternatives essential for ongoing system support, design updates, and procurement continuity. Direct substitutes maintain identical electrical and mechanical specifications while offering improved availability and compliance status.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ADC10738CIWM is determined by strict equivalence across the following critical parameters:

• Resolution and Sampling Rate: 10-bit resolution at 74 kHz sampling rate
• Channel Configuration: 8 input channels with support for differential, pseudo-differential, and single-ended input modes
• Interface Protocol: SPI data interface for host communication
• Converter Architecture: SAR-based analog-to-digital conversion
• Supply Voltage Requirements: 5V analog and digital supply voltages
• Package and Pinout: 24-SOIC surface mount package with identical mechanical dimensions
• Temperature Rating: -40°C to 85°C operating range

Only parts meeting all these specifications are classified as direct substitutes. Packaging variants (such as tube versus alternative packaging) do not affect functional substitutability when the core device remains unchanged.

Parameter Comparison

Engineering Selection Recommendations

The ADC10738CIWM/NOPB serves as the direct functional equivalent to the ADC10738CIWM. Both devices are manufactured by Texas Instruments and maintain identical electrical specifications, pin configurations, and performance characteristics across all critical parameters.

The primary distinction between these parts is product lifecycle status and regulatory compliance. The ADC10738CIWM carries Obsolete designation, while the ADC10738CIWM/NOPB maintains Active status with ROHS3 compliance. For new designs, system updates, or long-term procurement planning, the ADC10738CIWM/NOPB is the appropriate selection due to its active product status and enhanced compliance posture.

Both devices share identical MSL (Moisture Sensitivity Level) ratings and REACH/ECCN classifications, ensuring equivalent handling and logistics requirements.

Frequently Asked Questions (FAQ)

Q: Can ADC10738CIWM/NOPB be used as a direct replacement for ADC10738CIWM in existing designs?

A: Yes. The ADC10738CIWM/NOPB is a direct functional equivalent with identical pin configuration, electrical specifications, and performance characteristics. No circuit modifications are required for substitution.

Q: What does the "/NOPB" suffix indicate?

A: The "/NOPB" suffix denotes "No Plumbum" (lead-free) packaging, indicating RoHS3 compliance. This is a packaging and compliance variant of the base ADC10738 device, not a functional modification.

Q: Why is the ADC10738CIWM listed as Obsolete?

A: Obsolete status indicates the part has been discontinued by the manufacturer. The ADC10738CIWM/NOPB represents the current active equivalent and is the recommended selection for procurement.

Q: Are there differences in sampling rate or resolution between these parts?

A: No. Both parts maintain identical 10-bit resolution and 74 kHz sampling rate specifications.

Q: Do both parts support the same input configurations?

A: Yes. Both the ADC10738CIWM and ADC10738CIWM/NOPB support differential, pseudo-differential, and single-ended input modes across 8 channels via SPI interface.

Q: What is the significance of the RoHS compliance difference?

A: The ADC10738CIWM/NOPB is RoHS3 compliant, meeting current environmental and regulatory requirements. For applications subject to RoHS regulations or customer compliance mandates, the ADC10738CIWM/NOPB is the appropriate selection.

Q: Are the package dimensions identical?

A: Yes. Both parts use the 24-SOIC package with identical dimensions (0.295", 7.50mm width) and surface mount mounting type.

Q: Is there a difference in operating temperature range?

A: No. Both parts operate across the identical -40°C to 85°C temperature range.
