Product details
Overview
TLE2072AIDR from Texas Instruments is a dual-channel JFET-input operational amplifier optimized for high-voltage, low-noise, high-speed precision applications. It delivers ±3.5 mV max input offset voltage (25°C), 17 nV/√Hz input voltage noise at 1 kHz, 10 MHz unity-gain bandwidth, ±19 V supply capability, and operates across −40°C to +85°C. It is used in oscilloscopes, electricity meters, and AC drive power stage modules.
For engineers reviewing the TLE2072AIDR datasheet, TLE2072AIDR pinout, TLE2072AIDR application, or TLE2072AIDR equivalent, this page provides verified specifications, SOIC-8 package details, real-world use cases in high-fidelity signal conditioning, and validated alternative options for design continuity and sourcing flexibility.
Technical Context
The TLE2072AIDR implements a JFET-input stage with on-chip Zener trimming for enhanced DC precision, enabling rail-to-rail differential input operation up to ±19 V supplies. Its 32 V/μs slew rate and 10.6 MHz unity-gain bandwidth support fast settling (0.25 μs to 10 mV) in closed-loop configurations with capacitive loads up to 25 pF.
It features low input bias current (±15 pA typ), high common-mode rejection (98 dB at ±15 V), and robust supply-voltage rejection (99 dB), making it suitable for high-impedance sensor interfaces and precision analog front-ends where noise, offset drift, and dynamic range are critical.
Key Specifications

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Channel 1) | High-impedance JFET node accepting negative feedback or signal inversion. |

| 3 | Output (Channel 1) | Class-AB output stage capable of ±20 mA continuous drive into resistive loads. |
| 4 | V– (Negative Supply) | Common return for both channels; must be decoupled locally to minimize PSRR degradation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual JFET-input op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL072CDR | Higher input offset (6 mV max), lower bandwidth (3 MHz), no Zener-trimmed offset - less precise DC performance. | General-purpose audio and non-critical signal conditioning where cost is prioritized over precision. | Choose when budget constraints outweigh need for low noise and tight offset specs. |
| OPA2134PA | Lower noise (8 nV/√Hz), higher CMRR (120 dB), but narrower supply range (±18 V max) and higher quiescent current (4 mA/ch). | High-end audio and medical instrumentation requiring ultra-low distortion and superior PSRR. | Choose when SNR and linearity are paramount and ±18 V supply suffices. |
Compared with TL072CDR and OPA2134PA, the TLE2072AIDR offers the optimal balance of low noise (17 nV/√Hz), tight offset (3.5 mV max), wide supply (±19 V), and industrial temperature range - making it uniquely suited for high-reliability test and energy infrastructure applications.

FAQ
What is the maximum supply voltage for the TLE2072AIDR?
The TLE2072AIDR supports a maximum supply voltage of ±19 V, as specified in its Absolute Maximum Ratings table. This wide supply range enables operation in legacy ±15 V systems and extended-range industrial supplies. Operation beyond ±19 V risks permanent damage. The device maintains full functionality down to ±2.25 V, supporting flexible power architecture design. Always observe recommended operating conditions and include local decoupling at Pins 4 and 8.
Does the TLE2072AIDR require external compensation for unity-gain stability?
No, the TLE2072AIDR is internally compensated and unity-gain stable. It can be used directly in buffer, inverting, or non-inverting configurations without external capacitors or resistors. This eliminates compensation-related layout sensitivity and reduces bill-of-materials count. Stability is verified across temperature and load conditions per TI's SLOS181D datasheet, including phase margin ≥56° at unity gain with 25 pF capacitive load.
What is the input offset voltage specification for the TLE2072AIDR at 25°C?
The TLE2072AIDR has a maximum input offset voltage of 3.5 mV at 25°C, as defined in Table 4-2 (TLE2072 Available Options) and confirmed in Section 6.15 of the datasheet. This applies to the 'A' grade (industrial temperature range). Typical offset is 0.47 mV at ±15 V supply. The Zener-trimmed design ensures tighter distribution than standard TLE2072 variants, improving system-level calibration accuracy in precision measurement circuits.
Can the TLE2072AIDR drive capacitive loads?
Yes, the TLE2072AIDR is characterized to drive up to 25 pF capacitive loads while maintaining stability and specified settling time (0.25 μs to 10 mV). For loads exceeding 25 pF, external isolation resistance (e.g., 10–100 Ω in series with the output) is recommended to prevent peaking or oscillation. The device's phase margin remains ≥56° under these conditions, ensuring reliable operation in active filter and cable-driving applications.
Is the TLE2072AIDR RoHS compliant and lead-free?
Yes, the TLE2072AIDR is RoHS compliant and lead-free, as confirmed by Texas Instruments' official product folder and packaging information. The SOIC-8 (D) package uses matte tin lead finish and meets JEDEC J-STD-020 moisture sensitivity level 3. Full compliance documentation, including substance declarations and test reports, is available via TI's Quality & Environmental Information portal using the TLE2072AIDR part number.
