Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DAC37J82IAAV are determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters establish substitution eligibility:

• 16-bit resolution with dual D/A converter configuration
• 10ns typical settling time
• Current-mode unbuffered output with differential capability
• JESD204B serial data interface
• Dual supply voltage ranges: 3.15V–3.45V (analog), 0.85V–0.95V (digital)
• INL/DNL specifications of ±6 LSB and ±4 LSB respectively
• Current source architecture
• Operating temperature range of -40°C to 85°C
• 144-FCBGA (10x10) package footprint
• Surface mount configuration
• RoHS3 compliance and REACH unaffected status

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

All three parts—DAC37J82IAAV, DAC38J82IAAV, and DAC39J82IAAV—are active production components from Texas Instruments with identical electrical specifications and mechanical packaging. Each part carries RoHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements. Selection among these equivalents may be based on inventory availability, lead time, or supply chain logistics, as all parts are functionally interchangeable within the specified parameter set. No performance differentiation exists between these parts based on the provided technical data.

Frequently Asked Questions (FAQ)

Q: Are DAC38J82IAAV and DAC39J82IAAV true substitutes for DAC37J82IAAV?

A: Yes. Both parts meet all electrical and mechanical substitution criteria, including 16-bit resolution, dual D/A converter configuration, JESD204B interface, identical supply voltage ranges, settling time, output type, and 144-FCBGA package specification. All three parts are active production components with equivalent compliance certifications.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes. The parts share identical package specifications (144-FCBGA, 10x10 footprint) and mounting type (surface mount), ensuring mechanical and electrical compatibility on the same circuit board layout without modification.

Q: What compliance certifications apply to all substitute parts?

A: All three parts are RoHS3 compliant and REACH unaffected. Moisture sensitivity level is rated at MSL 3 (168 hours) for all parts.

Q: Are there differences in ECCN or HTSUS classifications?

A: ECCN and HTSUS codes differ between parts and should be verified with the supplier for specific export or tariff classification requirements. These differences do not affect functional substitution.

Q: What inventory levels are available for each part?

A: DAC37J82IAAV has 1543 pcs in stock, DAC38J82IAAV has 1678 pcs, and DAC39J82IAAV has 936 pcs. Inventory levels may change and should be confirmed with the supplier.
