Engineering Selection Recommendations

AD7896ARZ is a direct manufacturer equivalent available in active production status with tube packaging. This part maintains identical electrical and mechanical specifications to the AD7896AR and carries ROHS3 compliance and REACH unaffected status, making it suitable for applications requiring regulatory compliance documentation.

AD7896BRZ is a parametric equivalent with identical functional specifications, also in active production with tube packaging. This part likewise carries ROHS3 compliance and REACH unaffected status. Higher inventory availability (4022 units) compared to AD7896ARZ (1308 units) may provide supply chain advantages.

Both substitute parts are functionally interchangeable with the obsolete AD7896AR at the circuit level. Selection between AD7896ARZ and AD7896BRZ should be based on component availability, lead time requirements, and supplier inventory status.

Frequently Asked Questions (FAQ)

Q: Can AD7896ARZ and AD7896BRZ be used interchangeably with AD7896AR?

A: Yes. Both parts maintain identical electrical specifications including 12-bit resolution, 100 kHz sampling rate, single-ended input configuration, SPI interface, and 8-SOIC packaging. They operate within the same supply voltage range (2.7V to 5.5V) and temperature range (-40°C to 85°C).

Q: What is the difference between AD7896ARZ and AD7896BRZ?

A: Both parts are parametrically equivalent with identical functional specifications. The primary differences are product status (both active), packaging format (both tube), and inventory availability. No electrical or mechanical differences exist between these parts.

Q: Is the 8-SOIC package compatible across all three part numbers?

A: Yes. All three parts use the same 8-SOIC (0.154", 3.90mm Width) surface mount package. PCB footprints and assembly processes are identical.

Q: Are there compliance differences between the substitute parts?

A: AD7896ARZ and AD7896BRZ both carry ROHS3 compliance and REACH unaffected status. The obsolete AD7896AR does not have these certifications documented. For applications requiring regulatory compliance, AD7896ARZ or AD7896BRZ are recommended.

Q: Can I use these parts in new designs?

A: AD7896ARZ and AD7896BRZ are in active production and suitable for new designs. The AD7896AR is obsolete and should not be specified for new applications.
