Key Parameters

Substitute Part Grouping Explanation

Substitution of the AD5372BCPZ-RL7 is determined by strict equivalence across the following core electrical and mechanical parameters:

• Resolution and Channel Count: 16-bit resolution with 32 independent D/A converters
• Output Characteristics: Buffered voltage output with external reference capability
• Interface Protocol: SPI and DSP data interface compatibility
• Linearity Performance: INL/DNL specifications of ±4 LSB (Max) and ±1 LSB (Max)
• Settling Time: 30µs maximum settling time
• Supply Voltage Ranges: Analog supply 9V ~ 16.5V and -4.5V ~ 16.5V; Digital supply 2.5V ~ 5.5V
• Temperature Range: -40°C to 85°C operating specification
• Base Product Architecture: String DAC topology

The AD5372BSTZ-REEL maintains electrical equivalence across all specified parameters while differing only in package form factor and product status classification.

Engineering Selection Recommendations

The AD5372BSTZ-REEL serves as the direct electrical equivalent to the AD5372BCPZ-RL7 for applications requiring 16-bit, 32-channel DAC functionality with buffered voltage outputs and external reference configuration.

Primary Advantage: The AD5372BSTZ-REEL maintains active product status with Analog Devices, ensuring continued availability and manufacturing support. This addresses the obsolescence constraint of the original AD5372BCPZ-RL7.

Compliance Consideration: The AD5372BSTZ-REEL carries ROHS3 compliance certification, meeting current environmental and regulatory requirements for component procurement in regulated industries.

Package Transition: The substitution requires PCB layout modification due to package form factor change from 64-VFQFN (9x9mm) to 64-LQFP (10x10mm). Both packages maintain surface mount compatibility and identical pin functionality. Footprint redesign and thermal management evaluation are necessary during integration.

Tape & Reel Packaging: The AD5372BSTZ-REEL is supplied in Tape & Reel format, suitable for automated assembly processes. The original AD5372BCPZ-RL7 packaging format is not specified in available data.

Frequently Asked Questions (FAQ)

Q: Are the AD5372BCPZ-RL7 and AD5372BSTZ-REEL electrically interchangeable?

A: Yes. Both components share identical electrical specifications across resolution (16-bit), channel count (32), output type (buffered voltage), data interface (SPI/DSP), settling time (30µs), supply voltage ranges, and linearity performance (INL/DNL). Electrical functionality is fully equivalent.

Q: What is the primary difference between these two parts?

A: The differences are packaging format and product status. The AD5372BCPZ-RL7 uses a 64-VFQFN package and is classified as obsolete. The AD5372BSTZ-REEL uses a 64-LQFP package, maintains active product status, and includes ROHS3 compliance certification.

Q: Can I use the AD5372BSTZ-REEL as a direct drop-in replacement?

A: No direct drop-in replacement is possible due to package form factor differences. The 64-VFQFN (9x9mm) and 64-LQFP (10x10mm) packages have different footprints, requiring PCB redesign. Pin functionality and electrical behavior remain identical, but physical layout modification is mandatory.

Q: What are the thermal considerations when switching packages?

A: The 64-VFQFN package includes an exposed pad for enhanced thermal dissipation. The 64-LQFP package does not feature an exposed pad. Thermal management strategy must be re-evaluated during the transition to ensure adequate heat dissipation for your specific application current and duty cycle.

Q: Is the AD5372BSTZ-REEL suitable for new designs?

A: Yes. The AD5372BSTZ-REEL is classified as active product status with ROHS3 compliance, making it appropriate for new design implementations. The obsolete status of the AD5372BCPZ-RL7 makes the AD5372BSTZ-REEL the recommended choice for ongoing development.

Q: Are there any supply chain advantages to using the AD5372BSTZ-REEL?

A: Yes. Active product status ensures continued manufacturing and distribution through Analog Devices and authorized distributors. The Tape & Reel packaging format supports high-volume automated assembly, potentially offering cost advantages in production environments.

Q: What is the Moisture Sensitivity Level (MSL) for both parts?

A: Both the AD5372BCPZ-RL7 and AD5372BSTZ-REEL carry MSL 3 rating with a 168-hour floor life specification. Identical moisture handling and storage requirements apply to both components.
