Engineering Selection Recommendations

For Direct Replacement (Identical Electrical Performance):

The TL082ACDR is the primary recommended substitute. It is electrically identical to the TL082ACD with matching slew rate (13V/µs), gain bandwidth product (3 MHz), input bias current (30 pA), and supply voltage range (10V–30V). The TL082ACDR holds active product status and is available in Cut Tape and Digi-Reel packaging with 100,098 units in stock, ensuring long-term availability. Both parts are ROHS3 compliant with MSL 1 rating.

For Improved Performance Within J-FET Architecture:

The AD8512ARZ from Analog Devices Inc. provides enhanced specifications while maintaining J-FET input characteristics and the 10V–30V supply range. It offers superior slew rate (20V/µs versus 13V/µs), higher gain bandwidth product (8 MHz versus 3 MHz), lower input bias current (25 pA versus 30 pA), and extended operating temperature range (-40°C to 125°C versus 0°C to 70°C). This part is active and ROHS3 compliant. Selection of AD8512ARZ is appropriate when improved dynamic performance and wider temperature operation are required.

For High-Bandwidth Applications:

The ISL55002IBZ, ISL55002IBZ-T13, and ISL55002IBZ-T7 are voltage feedback amplifiers suitable for applications requiring significantly higher bandwidth (70 MHz gain bandwidth product, 300V/µs slew rate). These parts operate across 4.5V–30V supply range and are active products from Renesas Electronics Corporation. Selection is appropriate only when the application requires bandwidth performance substantially exceeding the TL082ACD specification.

For Audio-Specific Applications:

The LM833DT from STMicroelectronics is an audio amplifier with 15 MHz gain bandwidth product and 7V/µs slew rate, operating across 5V–30V supply range. This part is active and ROHS3 compliant. Selection is appropriate for audio signal processing applications where the TL082ACD's general-purpose characteristics are not optimized.

For Ultra-Low-Power Applications:

The LT2178ACS8#PBF and LT2178ACS8#TRPBF are general-purpose rail-to-rail amplifiers with ultra-low supply current (16µA) and extended supply range (2.2V–36V). These parts are active and ROHS3 compliant. Selection is appropriate only when supply current minimization is a primary design requirement and the reduced bandwidth (85 kHz) is acceptable.

Compliance Considerations:

All recommended substitutes maintain ROHS3 compliance and are suitable for applications requiring regulatory adherence. The TL082ACDR, TL082BCD, and TL082CMX/NOPB are from the same manufacturer (Texas Instruments) and base product family, minimizing design validation risk. Cross-manufacturer substitutes (AD8512ARZ, ISL55002 series, LM833DT, LT2178 series) require verification of electrical performance compatibility within the specific application circuit.

Frequently Asked Questions (FAQ)

Q1: Can the TL082ACDR be used as a direct drop-in replacement for the TL082ACD?

A: Yes. The TL082ACDR is electrically identical to the TL082ACD with matching slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, output current, and supply voltage range. Both parts are housed in 8-SOIC packages with identical pinouts. The primary difference is product status (TL082ACDR is active) and packaging format (TL082ACDR is available in Cut Tape and Digi-Reel). No circuit modifications are required.

Q2: What is the key difference between the TL082ACD and TL082CMX/NOPB?

A: The TL082CMX/NOPB has a fixed supply voltage specification of 36V (both minimum and maximum) compared to the TL082ACD's 10V–30V range. Additionally, the TL082CMX/NOPB exhibits higher supply current (3.6mA versus 1.4mA), higher input bias current (50 pA versus 30 pA), higher input offset voltage (5 mV versus 3 mV), and higher output current (17 mA versus 10 mA). The gain bandwidth product is slightly higher (4 MHz versus 3 MHz). These differences indicate the TL082CMX/NOPB is optimized for different operating conditions and should be selected only when these specifications align with application requirements.

Q3: Why would I select the AD8512ARZ over the TL082ACDR?

A: The AD8512ARZ is selected when improved dynamic performance is required. It provides 54% higher slew rate (20V/µs versus 13V/µs), 167% higher gain bandwidth product (8 MHz versus 3 MHz), lower input bias current (25 pA versus 30 pA), and significantly lower input offset voltage (100 µV versus 3 mV). The AD8512ARZ also operates across an extended temperature range (-40°C to 125°C versus 0°C to 70°C). These improvements are appropriate for applications requiring faster signal settling, higher frequency response, or operation in extreme temperature environments. The AD8512ARZ is from a different manufacturer (Analog Devices Inc.) and requires verification of circuit compatibility.

Q4: Are the ISL55002 parts suitable replacements for the TL082ACD?

A: The ISL55002 series (ISL55002IBZ, ISL55002IBZ-T13, ISL55002IBZ-T7) are voltage feedback amplifiers, not J-FET amplifiers. While they share the 8-SOIC package and operate within the 4.5V–30V supply range, they represent a fundamentally different amplifier architecture with substantially higher performance (300V/µs slew rate, 70 MHz gain bandwidth product). These parts are suitable only for applications requiring high-bandwidth performance and where the voltage feedback architecture is compatible with the circuit design. Direct substitution without circuit analysis is not recommended.

Q5: What is the difference between the LT2178ACS8#PBF and LT2178ACS8#TRPBF?

A: Both parts are electrically identical general-purpose rail-to-rail amplifiers with identical electrical specifications. The primary difference is packaging format: LT2178ACS8#PBF is supplied in Tube packaging, while LT2178ACS8#TRPBF is supplied in Tape & Reel (TR) packaging. Selection between these two is based on procurement and assembly process requirements, not electrical performance.

Q6: Can I use the LM833DT as a substitute for the TL082ACD in a general-purpose application?

A: The LM833DT is an audio-specific amplifier and should be selected only for audio signal processing applications. While it shares the 8-SOIC package and operates within a compatible supply range (5V–30V), it has lower slew rate (7V/µs versus 13V/µs) and higher input bias current (300 nA versus 30 pA). The LM833DT is optimized for audio frequencies and may not provide equivalent performance in general-purpose analog signal processing applications. Application-specific verification is required.

Q7: What does "obsolete" product status mean for the TL082ACD?

A: Obsolete status indicates that Texas Instruments has discontinued active manufacturing and support for the TL082ACD. However, 65,840 units remain in stock. For new designs or long-term production requirements, selection of an active product substitute (such as TL082ACDR) is recommended to ensure continued component availability and manufacturer support. Existing designs using the TL082ACD can continue operation with available inventory, but future procurement may become limited.

Q8: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed in this reference are ROHS3 compliant, matching the compliance status of the TL082ACD. This ensures compatibility with regulatory requirements for restricted substances in electrical and electronic equipment.

Q9: What is the significance of the 8-SOIC package specification?

A: The 8-SOIC (Small Outline Integrated Circuit) package is a surface mount package with 0.154 inches (3.90mm) width. All substitute parts maintain this identical package specification, ensuring mechanical and electrical compatibility with existing printed circuit board layouts. No PCB redesign is required when substituting between parts with matching 8-SOIC packages.

Q10: How do I determine which substitute part is appropriate for my application?

A: Selection depends on three primary factors: (1) Required electrical performance (slew rate, gain bandwidth product, input bias current, output current), (2) Operating conditions (supply voltage range, temperature range), and (3) Application type (general-purpose, audio, high-bandwidth). Compare your application requirements against the parameter comparison table. For identical performance, select TL082ACDR. For improved performance within J-FET architecture, select AD8512ARZ. For specialized applications (audio, high-bandwidth, ultra-low-power), select the appropriate part from the corresponding group. When in doubt, consult the detailed parameter specifications and verify circuit compatibility before implementation.
