Package / Case (8-SOIC form factor)
Mounting Type (Surface Mount)
Operating Temperature Range (-40°C to 85°C minimum)
Supply Voltage Range (minimum 4.5V to 38V maximum)

Electrical Performance Parameters:

Slew Rate (45 V/µs)
Gain Bandwidth Product (10 MHz)
Input Bias Current (1 pA)
Input Offset Voltage (300 µV)
Output Current per Channel (48 mA)

Substitute parts are grouped into two categories:

Category 1: Direct Equivalents (J-FET Amplifiers) Parts maintaining identical amplifier topology (J-FET input), dual-channel configuration, and 8-SOIC packaging. These include TLE2072IDR (Texas Instruments, Active status), LT1057 variants (Analog Devices Inc., Active status), and LT1169CS8#PBF (Analog Devices Inc., Active status). These substitutes preserve the high input impedance and low input bias current characteristics of the original design.

Category 2: Functional Alternatives (General Purpose and Audio Amplifiers) Parts with different amplifier topologies (General Purpose or Audio) that maintain dual-channel configuration and 8-SOIC packaging. These include AS358AMTR-E1 (Diodes Incorporated, General Purpose) and LM833 variants (onsemi and STMicroelectronics, Audio). These alternatives provide functional amplification capability but with different electrical characteristics and operating parameters.

Engineering Selection Recommendations

Primary Recommendation: TLE2072IDR

The TLE2072IDR (Texas Instruments) is the manufacturer-recommended direct equivalent. This part maintains identical electrical specifications to the TLE2072ID, including J-FET amplifier topology, 45 V/µs slew rate, 10 MHz gain bandwidth product, and 1 pA input bias current. The TLE2072IDR is in Active product status with 15,322 units in stock, ensuring long-term availability. Packaging is available in Cut Tape (CT) and Digi-Reel® format. All compliance certifications (ROHS3, REACH Unaffected, EAR99) are identical. This substitution requires no circuit redesign or performance verification.

Secondary Recommendations: LT1057 Series (Analog Devices Inc.)

The LT1057IS8#TRPBF, LT1057IS8#PBF, LT1057S8#TRPBF, and LT1057S8#PBF maintain J-FET amplifier topology and dual-channel configuration in 8-SOIC packaging. These parts are in Active product status. Key differences include lower slew rate (13 V/µs versus 45 V/µs), lower gain bandwidth product (5 MHz versus 10 MHz), and higher minimum supply voltage requirement (20 V versus 4.5 V). The LT1057IS8 variants support the full -40°C to 85°C operating temperature range, while LT1057S8 variants are limited to 0°C to 70°C. These substitutes are suitable for applications where the reduced slew rate and bandwidth are acceptable and supply voltage constraints are met.

Tertiary Recommendation: LT1169CS8#PBF (Analog Devices Inc.)

The LT1169CS8#PBF is a J-FET amplifier in Active product status with 1,943 units in stock. This part maintains dual-channel configuration and 8-SOIC packaging. Electrical differences include significantly lower slew rate (4.2 V/µs), lower gain bandwidth product (5.3 MHz), and higher input offset voltage (600 µV versus 300 µV). Minimum supply voltage is 9 V. Operating temperature range is limited to 0°C to 70°C. This substitute is applicable only to applications with relaxed bandwidth and slew rate requirements.

Alternative Consideration: AS358AMTR-E1 (Diodes Incorporated)

The AS358AMTR-E1 is a General Purpose amplifier in Active product status with 300,200 units in stock. This part differs fundamentally in amplifier topology (General Purpose versus J-FET), resulting in significantly higher input bias current (20 nA versus 1 pA) and higher input offset voltage (2 mV versus 300 µV). Minimum supply voltage is 3 V. This substitute is suitable only for applications where high input impedance and low input bias current are not critical design requirements.

Alternative Consideration: LM833 Series (onsemi and STMicroelectronics)

The LM833DR2G (onsemi) and LM833DT (STMicroelectronics) are Audio amplifiers in Active product status. These parts differ in amplifier topology (Audio versus J-FET), resulting in higher input bias current (300 nA versus 1 pA) and lower slew rate (7 V/µs versus 45 V/µs). The LM833DT supports extended operating temperature to 105°C but has reduced maximum supply voltage (30 V versus 38 V). These substitutes are applicable to audio signal processing applications where J-FET input characteristics are not required.

Frequently Asked Questions (FAQ)

Q: Can the TLE2072IDR be used as a direct replacement for the TLE2072ID?

A: Yes. The TLE2072IDR is the manufacturer-recommended equivalent with identical electrical specifications, package type (8-SOIC), and operating temperature range (-40°C to 85°C). The only difference is packaging format (Cut Tape and Digi-Reel® versus Tube). No circuit modifications are required.

Q: What are the key differences between the TLE2072ID and LT1057 series?

A: The LT1057 series has lower slew rate (13 V/µs versus 45 V/µs), lower gain bandwidth product (5 MHz versus 10 MHz), and higher minimum supply voltage requirement (20 V versus 4.5 V). Both maintain J-FET input topology and dual-channel configuration in 8-SOIC packaging. The LT1057IS8 variants support -40°C to 85°C operation, while LT1057S8 variants are limited to 0°C to 70°C.

Q: Why is the AS358AMTR-E1 listed as a substitute if it has different input bias current?

A: The AS358AMTR-E1 is listed as a functional alternative for applications where high input impedance is not critical. It maintains dual-channel configuration and 8-SOIC packaging. However, the 20 nA input bias current (versus 1 pA) makes it unsuitable for precision high-impedance signal conditioning applications.

Q: Can the LM833 series replace the TLE2072ID in all applications?

A: No. The LM833 series uses Audio amplifier topology rather than J-FET input, resulting in significantly higher input bias current (300 nA) and lower slew rate (7 V/µs). These parts are suitable only for audio signal processing where J-FET input characteristics are not required.

Q: What is the significance of the "Last Time Buy" status for the TLE2072ID?

A: Last Time Buy status indicates that Texas Instruments has discontinued production of the TLE2072ID. The 100,298 units in stock represent the final available inventory. For new designs and long-term production, the TLE2072IDR (Active status) or alternative J-FET amplifiers (LT1057 series) are recommended.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed maintain ROHS3 compliance and Moisture Sensitivity Level 1 (Unlimited), matching the original TLE2072ID specifications.

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

A: TLE2072ID and TLE2072IDR: 4.5 V minimum. LT1057 series: 20 V minimum. LT1169CS8#PBF: 9 V minimum. AS358AMTR-E1: 3 V minimum. LM833 series: 5 V to 10 V minimum depending on manufacturer. Circuit design must accommodate these voltage requirements.

Q: Which substitute offers the best performance match to the TLE2072ID?

A: The TLE2072IDR provides identical electrical performance and is the manufacturer-recommended equivalent. For applications requiring J-FET input characteristics with Active product status, the TLE2072IDR is the optimal choice.

Q: Can packaging format differences affect circuit performance?

A: No. Packaging format differences (Tube, Cut Tape, Digi-Reel®, Tape & Reel) do not affect electrical performance or circuit functionality. These differences relate only to component handling, storage, and assembly processes. The 8-SOIC package form factor remains consistent across all listed substitutes.
