Engineering Selection Recommendations

Primary Recommendation: TLE2082AIDR

The TLE2082AIDR is the direct successor to the TLE2082AID, manufactured by Texas Instruments with Active product status. This part maintains identical electrical specifications (40 V/µs slew rate, 10 MHz gain bandwidth product, 20 pA input bias current) and mechanical compatibility (8-SOIC packaging). The TLE2082AIDR is ROHS3 compliant and carries MSL 1 rating, ensuring compatibility with standard manufacturing processes. This substitution requires no circuit redesign and provides the highest confidence for drop-in replacement applications.

Secondary Recommendation: AD8620BRZ-REEL7 or AD8620ARZ-REEL

The Analog Devices AD8620 series (specifically AD8620BRZ-REEL7 or AD8620ARZ-REEL) offers enhanced performance characteristics with 60 V/µs slew rate and 25 MHz gain bandwidth product. These parts maintain J-FET input architecture with superior input bias current (3 pA) and extended operating temperature range (-40°C to 125°C). Both variants are Active status with ROHS3 compliance and MSL 1 rating. The AD8620 series is suitable for applications where improved frequency response and temperature stability provide system benefits. Note: Supply voltage range differs (10 V to 26 V maximum versus 4.5 V to 38 V), requiring verification of application compatibility.

Conditional Recommendation: AD746JRZ

The AD746JRZ provides intermediate performance (75 V/µs slew rate, 13 MHz bandwidth) with Active status and ROHS3 compliance. This part is applicable for applications requiring enhanced slew rate performance while maintaining J-FET input characteristics. Operating temperature range is limited to 0°C to 70°C, and supply voltage range is 9 V to 36 V. Substitution requires verification of thermal and supply voltage requirements.

Not Recommended: TL082CMX/NOPB

The TL082CMX/NOPB exhibits significantly reduced performance (13 V/µs slew rate, 4 MHz bandwidth) and higher input bias current (50 pA). Operating temperature range is restricted to 0°C to 70°C. This part is suitable only for legacy applications where reduced performance specifications are acceptable and thermal requirements do not exceed 70°C.

Not Recommended: AS358AMTR-G1, LM358ADR2G

These general-purpose amplifiers employ different input stage architecture (not J-FET) and exhibit input bias current in the nanoampere range (20 nA to 45 nA), making them unsuitable for applications requiring the low input bias current characteristic of the TLE2082AID J-FET design.

Frequently Asked Questions (FAQ)

Q1: Can the TLE2082AID be directly replaced with the TLE2082AIDR?

A: Yes. The TLE2082AIDR is the direct Active-status replacement for the TLE2082AID. Both parts share identical electrical specifications, J-FET input architecture, and 8-SOIC packaging. No circuit modifications are required. The TLE2082AIDR is recommended as the primary substitution path.

Q2: What is the key difference between the TLE2082AID and AD8620 series?

A: The AD8620 series offers superior performance with 60 V/µs slew rate (versus 40 V/µs) and 25 MHz gain bandwidth product (versus 10 MHz). Input bias current is significantly lower (3 pA versus 20 pA). However, the AD8620 series has a reduced maximum supply voltage (26 V versus 38 V). Applications operating above 26 V supply voltage cannot use the AD8620 series without circuit modification.

Q3: Why are general-purpose amplifiers (AS358, LM358) listed if they are not recommended?

A: General-purpose amplifiers are included for reference to clarify substitution boundaries. These parts do not meet the J-FET input bias current requirement (20 pA) of the TLE2082AID and are therefore not suitable substitutes. Their inclusion demonstrates the importance of amplifier type selection in component substitution.

Q4: Can the TL082CMX/NOPB be used as a substitute?

A: The TL082CMX/NOPB is a J-FET amplifier in 8-SOIC packaging but exhibits reduced performance specifications (13 V/µs slew rate, 4 MHz bandwidth, 50 pA input bias current). Substitution is only acceptable for applications where these reduced specifications are compatible with system requirements. Operating temperature is limited to 0°C to 70°C, restricting use in extended-temperature applications.

Q5: What packaging options are available for substitute parts?

A: All recommended substitute parts are available in 8-SOIC surface mount packaging, maintaining mechanical compatibility with the TLE2082AID. Packaging variants include Tube (standard), Tape & Reel (TR), and Cut Tape (CT) with Digi-Reel options. Selection depends on procurement and assembly requirements. Electrical specifications remain identical across packaging variants.

Q6: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed in this document are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard manufacturing processes and long-term storage requirements.

Q7: What supply voltage range should be verified when substituting with AD8620 series?

A: The AD8620 series maximum supply voltage is 26 V, compared to 38 V for the TLE2082AID. Applications requiring supply voltages between 26 V and 38 V cannot use the AD8620 series without circuit redesign. Verify application supply voltage requirements before substitution.

Q8: How does input bias current affect circuit performance?

A: Input bias current determines the DC offset voltage developed across input impedance. The TLE2082AID specifies 20 pA input bias current. The AD8620 series provides 3 pA, reducing offset voltage by approximately 85% for equivalent input impedance. The TL082 series specifies 50 pA, increasing offset voltage by 150%. Applications with high input impedance or precision DC coupling require careful consideration of input bias current specifications.
