Product details
Overview
TLE2071ACD from Texas Instruments is a single-channel Excalibur low-noise, high-speed JFET-input operational amplifier optimized for precision analog signal conditioning in ±2.25V to ±19V supply systems. It delivers 10.6 MHz unity-gain bandwidth, 32 V/μs slew rate, 17 nV/√Hz input voltage noise at 1 kHz, ±300 µV typical input offset voltage, and operates across 0°C to 70°C ambient temperature - enabling use in digital multimeters and oscilloscope front-end amplifiers.
For engineers reviewing the TLE2071ACD datasheet, TLE2071ACD pinout, TLE2071ACD application, or TLE2071ACD equivalent, key selection criteria include its SOIC-8 package compatibility, rail-to-rail input capability (±10.9 V common-mode range at ±15 V supplies), low bias current (±15 pA), and guaranteed 2 mV max input offset voltage over temperature - critical for high-accuracy DC-coupled measurement paths.
Technical Context
The TLE2071ACD employs a JFET-input stage with on-chip Zener trimming for DC precision, supporting differential inputs up to the supply rails and delivering stable unity-gain operation without external compensation. Its architecture balances wide dynamic signal range (±19 V supply capability) with low-noise AC performance.
It features a high open-loop gain (>90 dB at 2 kΩ load), excellent CMRR (98 dB at ±15 V), and robust phase margin (56°–57°), making it suitable for closed-loop configurations requiring fast settling (0.4 µs to 1 mV for 10 V step) and minimal distortion (0.0032% THD+N).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | ±2.25 V to ±19 V - supports wide dynamic range in industrial and test equipment power rails |
| Unity-Gain Bandwidth | 10.6 MHz - enables stable amplification of signals up to ~10 MHz without peaking |
| Slew Rate | 32 V/μs - ensures faithful reproduction of fast transients in data acquisition front ends |
| Input Offset Voltage | Max 2 mV at 25°C (TLE2071A grade) - reduces DC error in precision sensor interfaces |
| Input Voltage Noise | 17 nV/√Hz at 1 kHz - minimizes noise contribution in low-level signal amplification |
| Input Bias Current | ±15 pA typical - preserves signal integrity in high-impedance source applications (e.g., piezoelectric sensors) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA211IDR | Lower noise (1.1 nV/√Hz), lower offset (±25 µV), but only ±18 V max supply and SOIC-8 package | Better for ultra-low-noise audio or precision DAC output buffers; less suitable for ±19 V industrial rails | Select OPA211IDR when noise dominates design budget and supply stays ≤±18 V |
| TL071CD | Higher offset (±10 mV), higher noise (18 nV/√Hz), same SOIC-8 package and ±18 V rating | Cost-optimized alternative where 2 mV offset tolerance is relaxed and 10.6 MHz bandwidth is not required | Select TL071CD for legacy designs or cost-sensitive production where TLE2071ACD's A-grade precision is unnecessary |
Compared with OPA211IDR and TL071CD, the TLE2071ACD uniquely combines ±19 V supply support, 2 mV max offset, and 17 nV/√Hz noise in a standard SOIC-8 - making it optimal for industrial test equipment requiring both wide voltage headroom and DC accuracy.

FAQ
What is the maximum supply voltage rating for the TLE2071ACD?
The TLE2071ACD supports a total supply voltage (VCC+ to VCC−) of up to 38 V, corresponding to ±19 V operation. This is specified in the Absolute Maximum Ratings table and enables use in high-dynamic-range industrial systems where ±15 V or ±18 V rails are insufficient. Operation beyond ±19 V risks permanent damage and violates TI's recommended operating conditions.
Does the TLE2071ACD require external compensation for unity-gain stability?
No, the TLE2071ACD is unity-gain stable without external compensation components. Its internal compensation ensures ≥56° phase margin at unity gain with 25 pF capacitive load and 2 kΩ load resistance, as verified in the datasheet's operating characteristics. This eliminates the need for external capacitors in most buffer or gain-of-one configurations.
What is the purpose of Pins 1 and 5 on the TLE2071ACD?
Pins 1 and 5 on the TLE2071ACD are offset null terminals (N1 and N2) used to minimize input offset voltage via an external 10 kΩ potentiometer connected between them, with the wiper grounded. This adjustment is optional and typically applied only in ultra-high-precision applications where the inherent ±2 mV max offset is insufficient.
How does the TLE2071ACD's input bias current compare to bipolar-input op amps?
The TLE2071ACD's ±15 pA typical input bias current is over 1000× lower than typical bipolar-input op amps (e.g., LM741: ~80 nA). This JFET-input characteristic prevents significant voltage drop across high-impedance sources (e.g., >1 MΩ sensor networks), preserving signal fidelity in applications like photodiode amplifiers and high-resistance bridge sensors.
Is the TLE2071ACD pin-compatible with other TLE207x variants in SOIC-8 packages?
Yes, all TLE207x single-channel variants (TLE2071C, TLE2071A, TLE2071I, TLE2071M) in the D (SOIC-8) package share identical pinouts and footprint. The TLE2071ACD can be substituted for TLE2071CD or TLE2071ID in existing layouts, provided temperature range (0°C to 70°C) and offset voltage (2 mV max) requirements are met.
