Engineering Selection Recommendations

J-FET Input Substitutes (LT1057 Series):

The LT1057IS8#PBF, LT1057IS8#TRPBF, LT1057S8#PBF, and LT1057S8#TRPBF maintain J-FET input stage architecture identical to the TLE2082CDR, preserving ultra-low input bias current characteristics (7 pA). These parts are suitable for applications requiring minimal input current loading. The LT1057 variants differ in operating temperature range and packaging format (Tube vs. Tape & Reel). All LT1057 variants are ROHS3 compliant and maintain Active product status. Supply voltage minimum requirement of 20 V restricts use to applications with higher supply rails compared to the TLE2082CDR minimum of 4.5 V.

Audio Amplifier Substitutes (OP275 Series):

The OP275GSZ, OP275GSZ-REEL, and OP275GSZ-REEL7 are audio-grade operational amplifiers with higher slew rate (22 V/µs) and output current capability (90 mA per channel) compared to the TLE2082CDR. These parts support extended supply voltage range (9 V to 44 V maximum) and wider operating temperature (-40°C to 85°C). OP275 variants differ only in packaging format (Tube vs. Cut Tape & Digi-Reel). All are ROHS3 compliant and Active status.

Audio Amplifier Substitutes (LM833 Series):

The LM833DR2G (onsemi) and LM833DT (STMicroelectronics) are audio operational amplifiers with 15 MHz gain bandwidth product, exceeding the TLE2082CDR specification. The LM833DT supports extended operating temperature to 105°C and lower minimum supply voltage (5 V). Both maintain ROHS3 compliance and Active product status. Output current per channel ranges from 29 mA (LM833DR2G) to 37 mA (LM833DT).

General Purpose Substitute (MC1458DT):

The MC1458DT is a general-purpose operational amplifier with reduced slew rate (0.8 V/µs) and gain bandwidth product (1 MHz). This part is suitable only for low-frequency applications and is not recommended for high-speed signal processing. ROHS3 compliant and Active status maintained.

Selection Criteria:

Choose J-FET input substitutes (LT1057 series) when ultra-low input bias current is critical and supply voltage exceeds 20 V. Select OP275 variants for audio applications requiring high output current and extended temperature range. Use LM833 series for general audio amplification with higher bandwidth. Avoid MC1458DT for applications requiring slew rates above 1 V/µs.

Frequently Asked Questions (FAQ)

Q: Can the LT1057 series directly replace the TLE2082CDR in all applications?

A: LT1057 variants maintain J-FET input architecture and low input bias current (7 pA vs. 20 pA), making them functionally compatible. However, the minimum supply voltage requirement of 20 V restricts use to applications with higher supply rails. The TLE2082CDR operates from 4.5 V minimum, providing greater flexibility in low-voltage designs.

Q: What is the primary difference between OP275GSZ, OP275GSZ-REEL, and OP275GSZ-REEL7?

A: These three parts are electrically identical. The differences are packaging format only: OP275GSZ is supplied in Tube packaging, while OP275GSZ-REEL and OP275GSZ-REEL7 are supplied in Cut Tape & Digi-Reel format. Selection depends on assembly process requirements and inventory management preferences.

Q: Is the MC1458DT suitable as a substitute for the TLE2082CDR?

A: The MC1458DT shares the same 8-SOIC package and dual-circuit configuration. However, its slew rate of 0.8 V/µs and 1 MHz gain bandwidth product are significantly lower than the TLE2082CDR (45 V/µs and 10 MHz). Use MC1458DT only in low-frequency applications where bandwidth and slew rate are not critical.

Q: What are the key electrical differences between J-FET and Audio amplifier substitutes?

A: J-FET input amplifiers (TLE2082CDR, LT1057 series) feature ultra-low input bias current (7–20 pA range), making them suitable for high-impedance signal sources. Audio amplifiers (OP275, LM833) have higher input bias current (100–300 nA) but offer higher slew rates and output current capability, optimized for audio frequency applications.

Q: Can I use OP275GSZ in place of TLE2082CDR in a precision measurement circuit?

A: OP275GSZ has higher input bias current (100 nA vs. 20 pA) and different input offset voltage (1 mV vs. 1.1 mV). For precision measurement applications requiring minimal input loading, the LT1057 series is more appropriate. OP275 is better suited for audio and general-purpose applications.

Q: What is the operating temperature range difference between LM833DT and LM833DR2G?

A: LM833DT (STMicroelectronics) operates from -40°C to 105°C, while LM833DR2G (onsemi) operates from -40°C to 85°C. The LM833DT provides extended high-temperature capability, suitable for industrial and automotive applications requiring operation above 85°C.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed (LT1057 series, OP275 series, LM833 series, MC1458DT) maintain ROHS3 compliance and Active product status, ensuring regulatory alignment and long-term availability.

Q: What is the minimum supply voltage requirement for each substitute family?

A: TLE2082CDR: 4.5 V minimum. LT1057 series: 20 V minimum. OP275 series: 9 V minimum. LM833DR2G: 10 V minimum. LM833DT: 5 V minimum. MC1458DT: 5 V minimum. Application supply voltage must meet or exceed the substitute part minimum specification.
