TL052CPSR Equivalent & Substitute Parts
Part Overview
The TL052CPSR is a J-FET input operational amplifier manufactured by Texas Instruments, featuring dual circuits in an 8-SO surface mount package. This device is classified as Last Time Buy, indicating discontinued production with limited availability. The TL052CPSR operates across a 10V to 30V supply range with a slew rate of 20.7V/µs and 3 MHz gain bandwidth product, making it suitable for precision analog signal processing applications requiring low input bias current (30 pA) and low input offset voltage (650 µV).
Substitute parts are necessary due to the Last Time Buy status of the TL052CPSR. Alternative J-FET operational amplifiers with compatible electrical and mechanical specifications provide continued design support and production continuity.

Engineering Selection Recommendations
Primary Substitute - Same Manufacturer: The TL052CDR is the recommended primary substitute. Manufactured by Texas Instruments, it maintains identical electrical specifications to the TL052CPSR while offering Active product status. The TL052CDR differs only in packaging format (Cut Tape & Digi-Reel versus Tape & Reel) and is suitable for both manual and automated assembly processes. This part provides direct functional equivalence with superior availability.
Secondary Substitutes - Analog Devices AD712 Series: The AD712JRZ and AD712KRZ are functionally compatible alternatives from Analog Devices Inc. Both parts meet or exceed the electrical requirements of the TL052CPSR with improved specifications: lower input bias current (25 pA versus 30 pA), lower input offset voltage (300 µV versus 650 µV), and extended supply voltage range (9V to 36V versus 10V to 30V). These parts are supplied in Tube packaging and maintain Active product status.
Extended Temperature Range Substitutes - Analog Devices AD8682 Series: The AD8682ARZ, AD8682ARZ-REEL, and AD8682ARZ-REEL7 provide extended operating temperature range (-40°C to 85°C) compared to the TL052CPSR (0°C to 70°C). These parts feature significantly lower supply current (0.21 mA versus 4.8 mA), making them suitable for low-power applications. The AD8682ARZ-REEL and AD8682ARZ-REEL7 are available in Tape & Reel packaging for automated assembly. Trade-offs include reduced slew rate (9V/µs versus 20.7V/µs) and lower output current per channel (12 mA versus 80 mA).
Low-Power Extended Temperature Substitutes - Analog Devices LT1057 Series: The LT1057IS8, LT1057IS8#PBF, LT1057IS8#TRPBF, and LT1057S8#PBF offer superior performance in specific parameters: higher gain bandwidth product (5 MHz versus 3 MHz), lower input bias current (7 pA versus 30 pA), and lower input offset voltage (220 µV versus 650 µV). The LT1057 series features significantly reduced supply current (1.7 mA versus 4.8 mA). Extended temperature variants (LT1057IS8 series) operate from -40°C to 85°C. The LT1057S8#PBF maintains the original 0°C to 70°C temperature range. Minimum supply voltage requirement is 20V (versus 10V for TL052CPSR). All LT1057 variants are supplied in 8-SO packaging with Tube or Tape & Reel options available.
Compliance and Certification: All substitute parts maintain ROHS3 compliance and Moisture Sensitivity Level 1 (Unlimited), ensuring compatibility with modern manufacturing and environmental standards.
Frequently Asked Questions (FAQ)
Q: Can the TL052CDR directly replace the TL052CPSR in existing designs?
A: Yes. The TL052CDR is electrically and functionally identical to the TL052CPSR. Both parts share the same base product number (TL052), identical electrical specifications, and compatible 8-SOIC/8-SO package pinouts. The only difference is packaging format (Cut Tape & Digi-Reel versus Tape & Reel). PCB layout and schematic connections require no modification.
Q: What are the key differences between the AD712 series and the TL052CPSR?
A: The AD712JRZ and AD712KRZ offer improved electrical performance: lower input bias current (25 pA versus 30 pA), lower input offset voltage (300 µV versus 650 µV), and extended supply voltage range (9V to 36V versus 10V to 30V). Slew rate is marginally lower (20V/µs versus 20.7V/µs). Output current per channel is reduced (25 mA versus 80 mA). These parts are suitable for precision analog applications where lower input offset voltage is beneficial.
Q: When should I use the AD8682 series instead of the TL052CPSR?
A: The AD8682 series is recommended for low-power applications where supply current is critical. The AD8682 consumes only 0.21 mA (dual channels) compared to 4.8 mA for the TL052CPSR, representing a 23-fold reduction. Extended temperature operation (-40°C to 85°C) is available. Trade-offs include reduced slew rate (9V/µs) and lower output current (12 mA per channel). The AD8682ARZ-REEL and AD8682ARZ-REEL7 are available in Tape & Reel packaging for automated assembly.
Q: What are the advantages of the LT1057 series?
A: The LT1057 series provides superior performance in multiple parameters: higher gain bandwidth product (5 MHz versus 3 MHz), significantly lower input bias current (7 pA versus 30 pA), and lower input offset voltage (220 µV versus 650 µV). Supply current is reduced to 1.7 mA (dual channels). Extended temperature variants operate from -40°C to 85°C. The primary limitation is minimum supply voltage of 20V (versus 10V for TL052CPSR), which may restrict use in low-voltage applications.
Q: Are all substitute parts available in Tape & Reel packaging?
A: Not all variants. The TL052CDR is available in Cut Tape & Digi-Reel format. The AD712JRZ and AD712KRZ are supplied in Tube packaging only. The AD8682ARZ-REEL and AD8682ARZ-REEL7 are available in Tape & Reel format. The LT1057IS8#TRPBF and LT1057IS8 are available in Tape & Reel format. Verify packaging availability with your supplier before design selection.
Q: Can I use a substitute part with a lower supply voltage minimum (9V) in a 10V minimum design?
A: The AD712 series and AD8682 series specify 9V minimum supply voltage, which is lower than the TL052CPSR requirement of 10V. However, design margins and actual circuit operating conditions must be evaluated. Consult device datasheets for recommended operating conditions and performance specifications at the intended supply voltage.
Q: What is the difference between AD8682ARZ-REEL and AD8682ARZ-REEL7?
A: Both parts are electrically identical with identical specifications. The suffix "-REEL7" indicates a different reel configuration or packaging specification. Electrical performance, pin configuration, and functional characteristics are equivalent. Verify reel specifications with your supplier for compatibility with your assembly equipment.
Q: Are all substitute parts RoHS3 compliant?
A: Yes. All substitute parts listed maintain ROHS3 compliance and Moisture Sensitivity Level 1 (Unlimited), ensuring compatibility with modern manufacturing processes and environmental regulations.
Q: Which substitute offers the best balance of performance and availability?
A: The TL052CDR provides the most direct replacement with identical electrical specifications, Active product status, and superior availability (18,960 pieces in stock). For applications requiring extended temperature operation or low-power performance, the LT1057 series offers superior specifications with Active status and good availability.
