TL082ACDRG4 Equivalent & Substitute Parts

Part Overview

The TL082ACDRG4 is a J-FET input operational amplifier featuring dual circuits in an 8-SOIC surface mount package, manufactured by Texas Instruments. This device is classified as obsolete product status. The TL082ACDRG4 operates across a supply voltage range of 10V to 30V with a slew rate of 13V/µs and gain bandwidth product of 3 MHz, making it suitable for general-purpose analog signal processing applications requiring low input bias current characteristics.

Due to obsolete product status, equivalent substitute parts with active availability are necessary for new designs and production continuity. Substitute selection must maintain electrical compatibility within the specified parameter tolerances and mechanical compatibility with the 8-SOIC package format.

Engineering Selection Recommendations

Primary Recommendation - Direct Equivalent:

TL082ACDR is the recommended substitute for TL082ACDRG4. This part maintains identical electrical specifications across all critical parameters: J-FET amplifier type, dual circuits, 13V/µs slew rate, 3 MHz gain bandwidth product, 30 pA input bias current, and 10V to 30V supply voltage range. The primary difference is product status (Active vs. Obsolete) and packaging format (Cut Tape & Digi-Reel® vs. Tape & Reel). Both are ROHS3 compliant with MSL 1 rating. This substitution requires no circuit redesign or validation.

Secondary Recommendation - Enhanced Performance:

TL072CDT offers improved performance characteristics while maintaining J-FET topology and 8-SOIC package compatibility. This part provides higher slew rate (16V/µs vs. 13V/µs), improved gain bandwidth product (4 MHz vs. 3 MHz), lower input bias current (20 pA vs. 30 pA), and extended supply voltage range (6V to 36V vs. 10V to 30V). Product status is Active with AEC-Q100 automotive qualification. This substitution is suitable for applications requiring enhanced performance margins.

Alternative Recommendation - Superior Specifications:

AD8512ARZ and AD8512ARZ-REEL provide superior electrical performance with J-FET input stage. These parts feature higher slew rate (20V/µs), higher gain bandwidth product (8 MHz), lower input bias current (25 pA), and significantly lower input offset voltage (100 µV vs. 3 mV). Extended operating temperature range (-40°C to 125°C) and active product status support long-term availability. Supply voltage range (10V to 30V) matches the original specification. These substitutions are suitable for precision applications requiring lower offset voltage and higher bandwidth.

Not Recommended - Functional Alternatives:

MC33172 series (MC33172D, MC33172DT, MC33172VDR2G) and LM833DT employ different amplifier topologies (General Purpose and Audio respectively) with significantly different electrical characteristics. Input bias current is substantially higher (20 nA to 300 nA vs. 30 pA), slew rate is lower (2V/µs to 7V/µs vs. 13V/µs), and gain bandwidth product is lower (1.8 MHz to 15 MHz). These parts are suitable only for applications where J-FET input characteristics are not required and where the different performance envelope is acceptable.

These parts are suitable only for applications where J-FET input characteristics are not critical.

Q5: What packaging formats are available for TL082ACDR?

A: TL082ACDR is available in Cut Tape (CT) & Digi-Reel® packaging format. The original TL082ACDRG4 is supplied in Tape & Reel (TR) format. Both formats are compatible with automated assembly equipment. Verify packaging requirements with your procurement specification before ordering.

Q6: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed in this document are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited). All parts are REACH Unaffected and classified as EAR99 for export control purposes.

Q7: What is the operating temperature range difference between TL082ACDRG4 and AD8512ARZ?

A: TL082ACDRG4 operates from 0°C to 70°C. AD8512ARZ operates from -40°C to 125°C, providing extended temperature range capability. This difference is significant for applications requiring operation outside the 0°C to 70°C envelope. Verify application temperature requirements before selecting a substitute.

Q8: Can TL072CDT be used in place of TL082ACDRG4?

A: TL072CDT is a suitable substitute with enhanced performance characteristics. Both are J-FET input amplifiers in 8-SOIC packages with compatible supply voltage ranges. TL072CDT provides higher slew rate (16V/µs vs. 13V/µs), higher gain bandwidth product (4 MHz vs. 3 MHz), and lower input bias current (20 pA vs. 30 pA). This substitution is suitable for applications where improved performance margins are beneficial.
