Key Parameters

Substitute Part Grouping Explanation

Substitution of the ADA4610-2ARMZ-RL is determined by the following criteria:

Functional Equivalence Parameters:

• Dual-channel configuration (2 circuits)
• Rail-to-rail output capability
• Surface mount packaging in 8-pin MSOP/TSSOP form factor
• Operating temperature range of -40°C to 125°C
• Supply voltage compatibility within specified ranges
• Output current capability sufficient for target applications

Electrical Performance Considerations:

• Slew rate, gain bandwidth product, and -3dB bandwidth define signal processing speed
• Input bias current and input offset voltage determine precision and noise characteristics
• Supply current consumption affects power budget
• Output current per channel establishes load-driving capability

Compliance and Environmental Factors:

• RoHS3 compliance status
• Moisture sensitivity level (MSL) rating
• REACH and ECCN classifications

The OPA2172QDGKQ1 qualifies as a substitute based on matching the dual-channel, rail-to-rail, surface mount 8-pin configuration and operating temperature range. Differences in amplifier topology (General Purpose vs. J-FET), slew rate, and supply voltage span are documented in the parameter comparison table below.

Engineering Selection Recommendations

ADA4610-2ARMZ-RL Selection Criteria:

The ADA4610-2ARMZ-RL is the primary choice for applications requiring J-FET input stage characteristics, specifically the ultra-low input bias current of 5 pA and higher slew rate of 61 V/µs. The device supports supply voltages from 10 V to 30 V and maintains ROHS3 compliance with MSL 1 rating (unlimited moisture sensitivity). Active production status ensures long-term availability.

OPA2172QDGKQ1 Substitution Criteria:

The OPA2172QDGKQ1 serves as a substitute in applications where General Purpose amplifier topology is acceptable and where the extended supply voltage range (4.5 V to 36 V) provides system design flexibility. This device carries automotive-grade qualification (AEC-Q100) and is suitable for automotive applications. The lower slew rate (10 V/µs) and gain bandwidth product (10 MHz) represent reduced performance compared to the ADA4610-2ARMZ-RL. The MSL 2 rating requires controlled storage conditions (1 year maximum). Both devices maintain active production status and ROHS3 compliance.

Substitution Feasibility:

Direct substitution is feasible when application requirements do not mandate J-FET input characteristics or the higher speed performance of the ADA4610-2ARMZ-RL. Pin-compatible 8-pin MSOP/VSSOP packages support direct PCB layout compatibility. Supply voltage requirements must fall within the OPA2172QDGKQ1 range (4.5 V to 36 V) for successful substitution.

Frequently Asked Questions (FAQ)

Q: Can the OPA2172QDGKQ1 directly replace the ADA4610-2ARMZ-RL on a PCB?

A: Both devices use 8-pin surface mount packages (MSOP and VSSOP respectively) with compatible pinouts for dual-channel operational amplifiers. Physical footprint compatibility exists for standard 8-pin MSOP/VSSOP land patterns. Electrical compatibility depends on application-specific requirements for slew rate, bandwidth, and input bias current performance.

Q: What are the key performance differences between these two devices?

A: The ADA4610-2ARMZ-RL features J-FET input topology with 61 V/µs slew rate and 16.3 MHz gain bandwidth product. The OPA2172QDGKQ1 uses General Purpose topology with 10 V/µs slew rate and 10 MHz gain bandwidth product. The ADA4610-2ARMZ-RL provides lower input bias current (5 pA vs. 8 pA) and higher input offset voltage (400 µV vs. 200 µV). Supply voltage ranges differ: ADA4610-2ARMZ-RL operates from 10 V to 30 V, while OPA2172QDGKQ1 operates from 4.5 V to 36 V.

Q: Are there supply voltage compatibility issues when substituting?

A: The ADA4610-2ARMZ-RL requires minimum 10 V supply voltage. The OPA2172QDGKQ1 operates at lower voltages starting from 4.5 V. If the application uses supply voltages below 10 V, the ADA4610-2ARMZ-RL cannot be used. Conversely, both devices support the 10 V to 30 V range, making substitution feasible within this overlap region.

Q: What is the significance of the MSL rating difference?

A: The ADA4610-2ARMZ-RL carries MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage and handling. The OPA2172QDGKQ1 carries MSL 2 (1 Year), requiring controlled storage conditions with maximum one-year shelf life before use. This affects component procurement, inventory management, and handling procedures.

Q: Does the automotive qualification of the OPA2172QDGKQ1 affect substitution decisions?

A: The OPA2172QDGKQ1 holds AEC-Q100 automotive qualification, making it suitable for automotive applications. The ADA4610-2ARMZ-RL does not carry automotive qualification. For non-automotive applications, this difference is not relevant. For automotive applications, the OPA2172QDGKQ1 qualification status may be advantageous or required depending on system specifications.

Q: How do input offset voltage differences impact circuit design?

A: The ADA4610-2ARMZ-RL specifies 400 µV input offset voltage, while the OPA2172QDGKQ1 specifies 200 µV. Lower offset voltage in the OPA2172QDGKQ1 reduces DC error in precision applications. Applications with tight DC accuracy requirements may require offset nulling or calibration regardless of device selection. The choice depends on application tolerance specifications.

Q: Are both devices currently available for procurement?

A: Both devices maintain active production status. The ADA4610-2ARMZ-RL has 1425 units in current inventory. The OPA2172QDGKQ1 has 725 units in current inventory. Availability may vary based on procurement timing and supplier stock levels.
