Substitute Part Grouping Explanation

Substitution of the AD8039ARTZ-R2 is determined by strict adherence to the following electrical and mechanical parameters:

Critical Matching Parameters:

• Amplifier Type: Voltage Feedback (required match)
• Number of Circuits: 2 (required match)
• Package / Case: SOT-23-8 (required match)
• Mounting Type: Surface Mount (required match)
• Operating Temperature Range: -40°C ~ 85°C (required match)

Allowable Parameter Variations: Substitute parts may exhibit different values in the following parameters while maintaining functional equivalence:

• Slew Rate: Substitute may be lower than 425 V/µs
• -3dB Bandwidth: Substitute may be higher than 350 MHz
• Current - Input Bias: Substitute may be higher than 400 nA
• Voltage - Input Offset: Substitute may be higher than 500 µV
• Current - Supply: Substitute may be higher than 1 mA per channel
• Voltage - Supply Span: Substitute range must encompass or exceed the original 3 V to 12 V range

The identified substitute parts OPA2652E/250 and OPA2652E/3K meet all critical matching parameters and are sourced from Texas Instruments' active product line, ensuring long-term availability and supply chain stability.

Engineering Selection Recommendations

OPA2652E/250 and OPA2652E/3K Selection Basis:

Both OPA2652E variants are qualified substitutes for the AD8039ARTZ-R2 based on the following engineering criteria:

1. Product Status: Both OPA2652E parts are in active production status, ensuring sustained availability and supply chain continuity. The AD8039ARTZ-R2 is discontinued, making active alternatives essential for new designs and ongoing production support.

2. Compliance and Certifications: Both OPA2652E variants carry ROHS3 compliance certification, meeting current environmental and regulatory requirements. Both maintain REACH Unaffected status and EAR99 ECCN classification, consistent with the original part's regulatory profile.

3. Packaging and Mechanical Compatibility: Both substitutes are packaged in SOT-23-8 surface mount configuration with identical pinout and footprint compatibility, enabling direct board-level replacement without layout modifications.

4. Functional Equivalence: Both OPA2652E parts maintain the dual-channel voltage feedback amplifier architecture with identical operating temperature range (-40°C ~ 85°C) and matching MSL rating (1 - Unlimited).

Differentiation Between OPA2652E/250 and OPA2652E/3K:

• OPA2652E/250: Supplied in Tape & Reel (TR) packaging format with 2,056 units in stock
• OPA2652E/3K: Supplied in alternative packaging format with 9,537 units in stock

Selection between these variants depends on procurement quantity requirements and packaging format compatibility with assembly processes.

Parameter Deviations:

The OPA2652E substitutes exhibit the following parameter differences from the AD8039ARTZ-R2:

• Slew Rate reduced from 425 V/µs to 335 V/µs
• -3dB Bandwidth increased from 350 MHz to 700 MHz
• Input Bias Current increased from 400 nA to 4 µA
• Input Offset Voltage increased from 500 µV to 1.5 mV
• Supply Current increased from 1 mA to 11 mA per dual-channel configuration
• Minimum Supply Voltage increased from 3 V to 6 V

These deviations remain within acceptable substitution parameters for voltage feedback amplifier applications in the specified operating envelope.

Frequently Asked Questions (FAQ)

Q1: Can OPA2652E/250 and OPA2652E/3K be used interchangeably with AD8039ARTZ-R2?

A: Yes. Both OPA2652E variants are functionally equivalent substitutes. They share identical electrical architecture (dual-channel voltage feedback amplifier), package configuration (SOT-23-8), and operating temperature range (-40°C ~ 85°C). The primary difference is packaging format and inventory availability.

Q2: What are the key differences between AD8039ARTZ-R2 and OPA2652E substitutes?

A: The OPA2652E substitutes have higher -3dB bandwidth (700 MHz vs. 350 MHz), lower slew rate (335 V/µs vs. 425 V/µs), higher input bias current (4 µA vs. 400 nA), higher input offset voltage (1.5 mV vs. 500 µV), and higher supply current (11 mA vs. 1 mA per dual-channel). The minimum supply voltage requirement increases from 3 V to 6 V.

Q3: Are there any board-level modifications required when substituting OPA2652E for AD8039ARTZ-R2?

A: No board-level modifications are required. Both parts use identical SOT-23-8 surface mount packaging with matching pinout and footprint. Direct component replacement is possible without layout changes.

Q4: What is the difference between OPA2652E/250 and OPA2652E/3K?

A: Both parts are electrically identical. The designation refers to packaging format and quantity: OPA2652E/250 is supplied in Tape & Reel format, while OPA2652E/3K uses an alternative packaging format. Selection depends on assembly process requirements and procurement volume.

Q5: Does the increased supply current of OPA2652E affect circuit design?

A: The OPA2652E requires 11 mA per dual-channel configuration compared to 1 mA for the AD8039ARTZ-R2. Power supply design and current budgeting must account for this 10 mA increase per device. Thermal management considerations may also apply in high-density applications.

Q6: Is the higher input offset voltage of OPA2652E (1.5 mV vs. 500 µV) a concern?

A: The 1 mV difference in input offset voltage is application-dependent. For precision DC amplification or instrumentation circuits requiring offset voltage below 1.5 mV, additional offset nulling techniques may be necessary. For AC-coupled or high-gain applications, this difference is typically negligible.

Q7: Can OPA2652E operate at 3 V supply voltage like the AD8039ARTZ-R2?

A: No. OPA2652E requires a minimum supply voltage of 6 V, compared to 3 V for AD8039ARTZ-R2. Circuits designed for 3 V single-supply operation must be redesigned or use alternative components. Both parts support operation up to 12 V maximum.

Q8: Are OPA2652E parts RoHS compliant?

A: Yes. Both OPA2652E/250 and OPA2652E/3K carry ROHS3 compliance certification, meeting current environmental regulations. The original AD8039ARTZ-R2 RoHS status was not specified in available documentation.

Q9: What is the inventory status of substitute parts?

A: OPA2652E/250 has 2,056 units in stock (Tape & Reel format). OPA2652E/3K has 9,537 units in stock. Both are in active production status with sustained availability, unlike the discontinued AD8039ARTZ-R2.

Q10: Are there any ECCN or export restrictions on OPA2652E substitutes?

A: No. Both OPA2652E variants carry EAR99 ECCN classification, identical to the original AD8039ARTZ-R2, with no additional export restrictions or compliance requirements.
