Product details
Overview
TLE2071AIDR from Texas Instruments is a single-channel JFET-input operational amplifier optimized for high-voltage, low-noise, high-speed precision applications. It delivers ±300 µV typical input offset voltage, 17 nV/√Hz input voltage noise at 1 kHz, 10 MHz gain-bandwidth product, ±19 V supply capability, and operates across −40°C to +85°C. It serves as a signal-conditioning front-end in digital multimeters and oscilloscopes.
For engineers reviewing the TLE2071AIDR datasheet, TLE2071AIDR pinout, TLE2071AIDR application, or TLE2071AIDR equivalent, this page provides verified specifications, SOIC-8 package layout, real-world use cases in test equipment and energy metering, and validated alternative options with documented functional trade-offs.
Technical Context
The TLE2071AIDR uses Excalibur JFET-input architecture with on-chip Zener trimming for low offset drift. Its unity-gain stable design supports wide bandwidth (10 MHz GBW) and high slew rate (32 V/µs), enabling accurate amplification of fast transient signals without phase reversal under rail-to-rail differential input conditions.
It features rail-to-rail common-mode input range (down to V– – 0.5 V and up to V+ + 0.5 V), low input bias current (±15 pA), and high open-loop gain (>91 dB at ±5 V), making it suitable for high-impedance sensor interfaces and precision DC-coupled measurement paths where stability and noise floor are critical.

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA211IDR | Lower noise (1.1 nV/√Hz), lower offset (±25 µV), but narrower supply (±18 V max) and higher quiescent current (3.6 mA) | Better for ultra-low-noise audio or sensor signal chains; less suited for high-supply industrial rails | Select when noise dominates budget and supply is ≤±15 V; verify thermal dissipation in SOIC-8 |
| AD8610ARZ | Higher GBW (25 MHz), lower input bias (1 pA), but higher noise (2.5 nV/√Hz) and no offset null pins | Preferred for high-speed active filters or photodiode TIA; lacks trim capability for DC-critical calibration | Choose for bandwidth-sensitive designs needing >10 MHz closed-loop gain; avoid where manual offset calibration is required |
Compared with OPA211IDR and AD8610ARZ, the TLE2071AIDR uniquely balances ultra-low bias current, offset trim capability, and ±19 V operation-making it irreplaceable in high-voltage, field-calibratable instrumentation where long-term DC stability is non-negotiable.

FAQ
What is the maximum supply voltage rating for the TLE2071AIDR?
The TLE2071AIDR supports a total supply voltage range of ±2.25 V to ±19 V, meaning the absolute maximum difference between VCC+ and VCC− is 38 V. This allows direct integration into high-dynamic-range systems like AC charging station power monitors and industrial data loggers without external level-shifting circuitry.
Does the TLE2071AIDR include offset null pins, and how are they used?
Yes, the TLE2071AIDR includes dedicated offset null pins (Pin 1 and Pin 5). These connect to a 10-kΩ potentiometer wiper with each end tied to VCC+ and VCC−, enabling manual trimming of input offset voltage to <100 µV in final calibration-critical for high-accuracy DMM and metering applications where factory-trimmed offsets degrade over time and temperature.
Is the TLE2071AIDR unity-gain stable, and what does that mean for circuit design?
Yes, the TLE2071AIDR is unity-gain stable. This means it can be configured as a voltage follower (gain = 1) without external compensation components while maintaining ≥56° phase margin. Designers benefit from simplified schematics, reduced board space, and guaranteed stability in buffer, active filter, and gain-setting configurations-eliminating risk of oscillation in sensitive measurement paths.
How does the TLE2071AIDR's input bias current compare to bipolar-input op-amps, and why does it matter?
The TLE2071AIDR specifies ±15 pA typical input bias current-over 1000× lower than typical bipolar-input op-amps (e.g., LM741: ~80 nA). This drastically reduces voltage error across high-value feedback or source impedances (e.g., 10 MΩ shunt resistors in DMMs), preserving measurement accuracy and eliminating drift-induced calibration drift in battery-powered portable instruments.
Can the TLE2071AIDR drive capacitive loads, and what is its recommended maximum?
The TLE2071AIDR is characterized for stable operation with up to 25 pF capacitive load at unity gain (per datasheet Figure 6-15). Driving larger capacitive loads (e.g., long cables or ADC input capacitance) requires isolation resistance (≥100 Ω) in series with the output or external compensation. Uncompensated loads >50 pF may cause peaking or ringing due to phase margin reduction.
