Product details
Overview
TLE2071CDG4 from Texas Instruments is a single-channel JFET-input operational amplifier optimized for high-voltage, low-noise, high-speed precision applications. It delivers 10.6 MHz unity-gain bandwidth, 32 V/μs slew rate, ±19 V supply capability, 17 nV/√Hz input voltage noise at 1 kHz, and ±15 pA input bias current - enabling accurate signal conditioning in oscilloscopes, electricity meters, and flight control units.
For engineers reviewing the TLE2071CDG4 datasheet, TLE2071CDG4 pinout, TLE2071CDG4 application, or TLE2071CDG4 equivalent, key selection criteria include its rail-to-rail input operation, low offset drift (3.2 µV/°C), wide common-mode range (±10.9 V at ±15 V supplies), and SOIC-8 packaging suitable for space-constrained analog front-ends requiring stable DC precision and AC performance.
Technical Context
The TLE2071CDG4 employs Excalibur JFET-input architecture with on-chip Zener trimming for low initial offset and excellent thermal stability. Its internal compensation ensures unity-gain stability while supporting fast settling (0.4 µs to 1 mV for a 10 V step) and high open-loop gain (>95 dB at 10 kΩ load).
Designed for ±2.25 V to ±19 V dual-supply operation, it accepts differential inputs up to the supply rails and maintains CMRR >85 dB and PSRR >82 dB across temperature - making it suitable for high-dynamic-range data acquisition where input signal fidelity and power supply rejection are critical.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed, low-noise op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA211IDR | Lower noise (1.1 nV/√Hz), lower supply range (±18 V max), higher cost, no offset null pins | Better for ultra-low-noise audio or instrumentation; less suitable for legacy ±15 V systems needing offset trim | Select when noise dominates error budget and offset trimming is unnecessary |
| TL071CP | Higher noise (18 nV/√Hz), lower slew rate (13 V/μs), same SOIC-8 package, no offset null, lower cost | Acceptable for general-purpose audio and non-critical signal conditioning where speed and precision are relaxed | Select for cost-sensitive designs where 10.6 MHz bandwidth and 32 V/μs slew rate are not required |
Compared with OPA211IDR and TL071CP, the TLE2071CDG4 uniquely balances low noise (17 nV/√Hz), high slew rate (32 V/μs), ±19 V supply tolerance, and offset-null capability - making it optimal for industrial test equipment and energy metering where both precision and robustness are mandatory.

FAQ
What is the maximum supply voltage rating for the TLE2071CDG4?
The TLE2071CDG4 has an absolute maximum supply voltage of ±19 V, with recommended operating range from ±2.25 V to ±19 V. This allows direct use in legacy ±15 V industrial systems and high-headroom applications like active filters and transducer interfaces. Operation beyond ±19 V risks permanent damage per TI's Absolute Maximum Ratings table.
Does the TLE2071CDG4 support rail-to-rail input operation?
Yes, the TLE2071CDG4 supports rail-to-rail input operation: its common-mode input voltage range extends to within 0.9 V of the negative rail and up to 10.9 V below the positive rail at ±15 V supply. This eliminates the need for external level-shifting in bipolar signal chains and improves dynamic range in precision measurement circuits using the TLE2071CDG4.
What is the purpose of Pins 1 and 5 on the TLE2071CDG4?
Pins 1 and 5 on the TLE2071CDG4 are offset null terminals (N1 and N2) used to minimize input offset voltage via an external 10-kΩ potentiometer. While not required for basic operation - since the TLE2071CDG4 has a typical VIO of 300 µV and max of 4 mV - these pins enable fine-tuning in applications demanding sub-millivolt DC accuracy, such as calibrated sensor front-ends and metrology-grade instruments using the TLE2071CDG4.
How does the TLE2071CDG4 compare to the TL071 in terms of noise and speed?
The TLE2071CDG4 offers lower input voltage noise (17 nV/√Hz vs. 18 nV/√Hz for TL071) and significantly higher slew rate (32 V/μs vs. 13 V/μs), delivering superior transient fidelity and bandwidth (10.6 MHz vs. 3 MHz). Both share JFET inputs and SOIC-8 packaging, but the TLE2071CDG4's enhanced AC performance and tighter offset specs make it preferable for demanding applications like oscilloscope front-ends where the TLE2071CDG4 is deployed.
Is the TLE2071CDG4 unity-gain stable?
Yes, the TLE2071CDG4 is internally compensated for unity-gain stability, meaning it can be configured as a buffer (gain = 1) without external compensation components. Its phase margin is 56° at unity gain with 25 pF load, ensuring robust stability in low-gain configurations - a key advantage over decompensated op-amps that require minimum gain ≥5 for stability, especially in precision signal paths using the TLE2071CDG4.
