Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AD7572ALR10 are identified based on strict electrical and mechanical parameter alignment. The following criteria determine substitution eligibility:

Primary Substitution Criteria:

• Resolution: 12 bits
• Number of inputs: 1
• Input type: Single ended
• Architecture: SAR
• Data interface: Parallel
• Package: 24-SOIC surface mount
• Reference type: Internal

Substitute Categories:

Direct Manufacturer Substitute (AD7572AARZ03): Maintains identical electrical specifications and package configuration. Differs in product status (active vs. obsolete) and operating temperature range extension. Packaging format is tube rather than unspecified.

Similar Manufacturer Substitute (MX7572LCWG12+T): Maintains core 12-bit SAR ADC architecture with single-ended input and parallel interface in 24-SOIC package. Introduces specified sampling rate (308k per second) and defined S/H:ADC ratio (1:1). Operating temperature range matches the main part. Supply voltage specifications differ slightly in negative rail specification.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (AD7572AARZ03): The AD7572AARZ03 is the primary substitute for the obsolete AD7572ALR10. Both components share identical electrical specifications and package configuration. The AD7572AARZ03 offers extended operating temperature range (-40°C to 85°C versus 0°C to 70°C), ROHS3 compliance, and active product status with confirmed inventory availability. This part is suitable for applications requiring direct functional equivalence with improved environmental performance and regulatory compliance.

For Alternative Selection (MX7572LCWG12+T): The MX7572LCWG12+T maintains core ADC functionality with identical resolution, input configuration, and package format. This part introduces specified sampling rate and S/H:ADC ratio parameters not detailed in the main part specification. Operating temperature range matches the original component. The MX7572LCWG12+T features superior moisture sensitivity (MSL 1 versus MSL 3), indicating lower moisture absorption risk. Supply voltage specifications show minor differences in negative rail specification (-15V versus -11.4V ~ 16.5V). Selection of this part requires verification that the specified sampling rate and S/H:ADC ratio are compatible with system requirements.

Frequently Asked Questions (FAQ)

Q: Can AD7572AARZ03 be used as a direct replacement for AD7572ALR10? A: Yes. Both components are 12-bit SAR ADCs with single-ended input, parallel interface, internal reference, and identical 24-SOIC package configuration. The AD7572AARZ03 is the active equivalent with extended temperature range and regulatory compliance certifications.

Q: What are the key differences between AD7572AARZ03 and MX7572LCWG12+T? A: Both maintain 12-bit SAR ADC architecture and 24-SOIC packaging. The AD7572AARZ03 provides direct electrical equivalence to the original part. The MX7572LCWG12+T specifies sampling rate (308k per second) and S/H:ADC ratio (1:1), features lower moisture sensitivity (MSL 1), and has slightly different negative supply voltage specification (-15V versus -11.4V ~ 16.5V range).

Q: Are all substitute parts available in the same package? A: Yes. All listed parts use 24-SOIC (0.295", 7.50mm Width) surface mount packaging, ensuring mechanical and footprint compatibility.

Q: What is the significance of MSL rating differences? A: MSL (Moisture Sensitivity Level) indicates moisture absorption risk during storage and handling. MSL 3 (168 Hours) requires controlled storage conditions. MSL 1 (Unlimited) indicates minimal moisture sensitivity, reducing handling and storage requirements.

Q: Do the substitute parts meet current regulatory requirements? A: AD7572AARZ03 and MX7572LCWG12+T both carry ROHS3 compliance and REACH Unaffected status, meeting current environmental and regulatory standards. The original AD7572ALR10 regulatory status is not specified.

Q: What supply voltage considerations apply when selecting a substitute? A: All parts support 5V analog and digital supply. The AD7572ALR10 and AD7572AARZ03 specify -11.4V ~ 16.5V range for both supplies. The MX7572LCWG12+T specifies 5V and -15V. Verify system supply voltage compatibility before selection.
