Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AD8062ARMZ-RL are identified based on the following critical parameters that determine functional equivalence:

Primary Substitution Criteria:

• Dual-channel (2 circuit) configuration
• Rail-to-rail output capability
• Surface mount package with 8-pin MSOP/VSSOP footprint compatibility
• Supply voltage range overlap (minimum 2.5 V to 5.5 V common range)
• Operating temperature range of -40°C to 85°C or extended
• Output current capability of 40 mA or greater per channel
• RoHS3 compliance and REACH unaffected status

Secondary Performance Considerations:

• Slew rate performance (650 V/µs for AD8062ARMZ-RL)
• Bandwidth characteristics (-3dB Bandwidth 320 MHz for AD8062ARMZ-RL)
• Input bias current and input offset voltage specifications
• Supply current consumption

The identified substitute parts OPA2353EA/2K5 and OPA2354AIDGKR from Texas Instruments meet the primary substitution criteria through equivalent package footprint, dual-channel architecture, rail-to-rail output, and overlapping supply voltage specifications. Both devices are Active status products with RoHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

AD8062ARMZ-RL Primary Selection: The AD8062ARMZ-RL is the primary component choice when the application requires the specified slew rate of 650 V/µs and -3dB bandwidth of 320 MHz. This device supports supply voltages up to 8 V and maintains Active product status with RoHS3 compliance. Moisture sensitivity level 1 (Unlimited) provides extended shelf life without moisture bake requirements.

OPA2354AIDGKR Substitution: The OPA2354AIDGKR from Texas Instruments serves as a substitute when supply voltage is constrained to 5.5 V maximum and extended operating temperature range to 125°C is required. This device provides higher output current capability (100 mA per channel) and maintains voltage feedback amplifier architecture. The -3dB bandwidth of 250 MHz and slew rate of 150 V/µs are lower than the primary part but sufficient for applications not requiring the full performance envelope of the AD8062ARMZ-RL. Active product status and RoHS3 compliance are maintained.

OPA2353EA/2K5 Substitution: The OPA2353EA/2K5 from Texas Instruments is applicable when supply voltage is limited to 5.5 V maximum and lower slew rate performance (22 V/µs) is acceptable. This CMOS amplifier provides the lowest input bias current (0.5 pA) and reduced supply current consumption (5.2 mA). Selection of this device is appropriate for low-power, low-frequency applications where the bandwidth and slew rate specifications of the AD8062ARMZ-RL exceed application requirements. Active product status and RoHS3 compliance are maintained.

Compliance Considerations: All three devices are RoHS3 compliant and REACH unaffected. The AD8062ARMZ-RL and substitute parts carry ECCN classification EAR99 and HTSUS code 8542.33.0001. Moisture sensitivity level differences (MSL 1 for AD8062ARMZ-RL versus MSL 2 for both Texas Instruments devices) affect storage and handling requirements but do not impact functional performance.

Frequently Asked Questions (FAQ)

Q: Can OPA2353EA/2K5 directly replace AD8062ARMZ-RL in all applications?

A: No. The OPA2353EA/2K5 has significantly lower slew rate (22 V/µs versus 650 V/µs) and no specified -3dB bandwidth parameter. Direct substitution is limited to applications where the lower slew rate and bandwidth performance are acceptable. The supply voltage maximum of 5.5 V also restricts use in circuits requiring the full 8 V supply range of the AD8062ARMZ-RL.

Q: What is the package compatibility between AD8062ARMZ-RL and the substitute parts?

A: All three devices use 8-pin MSOP/VSSOP packages with 0.118" (3.00mm) width. The physical footprint is compatible for PCB layout purposes. However, the AD8062ARMZ-RL uses 8-MSOP packaging while OPA2353EA/2K5 and OPA2354AIDGKR use 8-VSSOP packaging. Verify that the specific supplier device package is compatible with your PCB design and assembly process.

Q: How do the supply voltage ranges differ between these devices?

A: The AD8062ARMZ-RL operates from 2.7 V to 8 V. Both Texas Instruments substitutes (OPA2353EA/2K5 and OPA2354AIDGKR) operate from 2.5 V to 5.5 V. Applications requiring supply voltages above 5.5 V cannot use the Texas Instruments alternatives. The 2.5 V minimum of the substitutes is lower than the 2.7 V minimum of the primary part, allowing operation in lower voltage systems.

Q: What are the differences in output current capability?

A: The AD8062ARMZ-RL provides 50 mA per channel. The OPA2353EA/2K5 provides 40 mA per channel, while the OPA2354AIDGKR provides 100 mA per channel. Applications requiring output currents above 50 mA per channel must use the OPA2354AIDGKR. Applications with output current requirements below 40 mA can use either substitute.

Q: How do the input bias current specifications compare?

A: The AD8062ARMZ-RL has input bias current of 3.5 µA. The OPA2353EA/2K5 has 0.5 pA (significantly lower), while the OPA2354AIDGKR has 3 pA (comparable). Lower input bias current reduces errors in high-impedance circuits. The OPA2353EA/2K5 is preferred for applications sensitive to input bias current effects.

Q: What is the significance of the different operating temperature ranges?

A: The AD8062ARMZ-RL and OPA2353EA/2K5 both operate from -40°C to 85°C. The OPA2354AIDGKR extends to -40°C to 125°C. Applications requiring operation above 85°C must use the OPA2354AIDGKR. The extended temperature range does not affect performance in standard -40°C to 85°C applications.

Q: How do moisture sensitivity levels affect component handling?

A: The AD8062ARMZ-RL has MSL 1 (Unlimited), meaning no moisture bake is required regardless of storage duration. Both Texas Instruments substitutes have MSL 2 (1 Year), requiring moisture bake if stored for more than one year in standard conditions. This affects inventory management and component preparation procedures but does not impact electrical performance.

Q: Which substitute part is best for low-power applications?

A: The OPA2353EA/2K5 consumes the lowest supply current at 5.2 mA (x2 channels) compared to 6.8 mA for the AD8062ARMZ-RL and 4.9 mA for the OPA2354AIDGKR. However, the OPA2354AIDGKR has the lowest total supply current. For applications prioritizing power consumption with acceptable performance trade-offs, the OPA2353EA/2K5 is appropriate when slew rate and bandwidth requirements are low.

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

A: Physical footprint compatibility exists for the 8-pin MSOP/VSSOP packages. However, electrical performance differences (slew rate, bandwidth, output current, supply voltage range) must be verified against circuit requirements. Schematic and layout review is necessary to confirm that supply voltage, output current, and frequency response specifications of the selected substitute are compatible with the application design.
