Product details
Overview
TLE2071AMFKB from Texas Instruments is a single-channel JFET-input operational amplifier optimized for high-voltage, low-noise precision signal conditioning in demanding industrial and test equipment. It delivers ±300 µV typical input offset voltage, 17 nV/√Hz input voltage noise at 1 kHz, 10 MHz unity-gain bandwidth, ±19 V supply capability, and operates across −55°C to +125°C. It serves as the front-end gain stage in oscilloscope vertical amplifiers and high-accuracy electricity metering circuits.
For engineers reviewing the TLE2071AMFKB datasheet, TLE2071AMFKB pinout, TLE2071AMFKB application, or TLE2071AMFKB equivalent, key selection criteria include its guaranteed low offset drift over temperature, rail-to-rail input common-mode range up to supply rails, and compatibility with high-impedance sensor interfaces requiring minimal bias current (±15 pA typical).
Technical Context
The TLE2071AMFKB uses a JFET-input differential pair with on-chip Zener trimming for DC precision, enabling stable operation under wide supply (±2.25 V to ±19 V) and temperature (−55°C to +125°C) ranges. Its architecture supports unity-gain stability and delivers 32 V/µs slew rate with 0.4 µs settling to 1 mV for 10 V steps.
It features a high open-loop gain (>91 dB), excellent CMRR (89 dB min), and supply-voltage rejection ratio (≥82 dB), making it suitable for DC-coupled instrumentation where common-mode interference and power supply ripple must be suppressed without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±2.25 V to ±19 V - Enables direct interface with ±15 V legacy systems and extended dynamic range in high-voltage data acquisition. |
| Input Offset Voltage (Typ) | ±300 µV - Reduces DC error in precision integrators and strain gauge amplifiers without manual nulling. |
| Input Voltage Noise | 17 nV/√Hz @ 1 kHz - Critical for preserving SNR in low-level audio and sensor signal chains. |
| Unity-Gain Bandwidth | 10.6 MHz - Supports stable closed-loop operation up to 10 MHz with gain ≥1, suitable for active filter design. |
| Input Bias Current (Typ) | ±15 pA - Allows use with high-impedance pH electrodes, photodiode transimpedance stages, and piezoelectric sensors. |
| Operating Temperature | −55°C to +125°C - Qualified for military, aerospace, and under-hood automotive applications per MIL-PRF-38535. |
| Slew Rate | 32 V/µs - Ensures faithful reproduction of fast transient signals in oscilloscope front ends and pulse amplification. |
Pinout & Package
LCCC-20 (FK) ceramic package with hermetic seal, 8.89 mm × 8.89 mm footprint, suitable for high-reliability and high-temperature environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 17–20 | No Connect (NC) | Unused internal pads; must remain unconnected to avoid parasitic coupling or thermal stress. |
| 5 | Inverting Input (IN−) | Differential input node with 1 pF common-mode capacitance; requires matched trace routing for optimal CMRR. |
| 6 | Non-Inverting Input (IN+) | High-impedance JFET input (10¹² Ω); sensitive to ESD-requires guard ring and proper PCB layout. |
| 7 | Output (OUT) | Capable of ±65 mA short-circuit current; drives 600 Ω loads with <0.1% THD+N at 1 kHz. |
| 8, 9 | Negative Supply (VCC−) | Return path for bias current and output swing; requires low-inductance decoupling near pin. |
| 10, 11 | Positive Supply (VCC+) | Supports up to ±19 V; internal protection diodes clamp transients beyond absolute max ratings. |
| 12, 13 | Offset Null 1 / Offset Null 2 | Adjustment terminals for fine-tuning input offset; connected to external potentiometer (10 kΩ) for <50 µV residual error. |
| 14–16 | No Connect (NC) | Internally isolated; floating connection avoids ground loops in multi-amplifier layouts. |
Key Features
| Feature | Design Value |
|---|---|
| Low input voltage noise | 17 nV/√Hz at 1 kHz enables sub-µV signal resolution in 16-bit+ data acquisition systems. |
| Rail-to-rail input common-mode range | Operates with inputs up to ±0.5 V beyond supply rails-eliminates level-shifting in ±15 V industrial I/O modules. |
| On-chip Zener-trimmed offset | Guarantees ≤2 mV max VIO over −55°C to +125°C-reduces calibration burden in field-deployed test gear. |
| Unity-gain stable architecture | Requires no external compensation for gains ≥1-simplifies design of active filters and buffer stages. |
| High CMRR and PSRR | ≥89 dB CMRR and ≥82 dB PSRR suppress 50/60 Hz line noise and supply ripple in precision analog front ends. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA277GP | Lower noise (10 nV/√Hz), but only ±18 V max supply and −40°C to +85°C temp range; no offset null pins. | Better for commercial-grade DMMs; unsuitable for extended temperature or fine-offset-adjustment needs. | Select when ultra-low noise dominates over temperature range and trimmable offset. |
| AD8610ARZ | Faster slew rate (65 V/µs), lower input bias (1 pA), but narrower supply (±13.5 V max) and higher cost; no military temp grade. | Ideal for high-speed portable test equipment; lacks radiation-hardened LCCC packaging and extended temp validation. | Select for battery-powered, high-bandwidth applications where size and power efficiency outweigh environmental ruggedness. |
Compared with OPA277GP and AD8610ARZ, the TLE2071AMFKB uniquely combines military-temperature operation, offset-null capability, and ±19 V supply tolerance-making it irreplaceable in aerospace, energy infrastructure, and high-reliability industrial control where long-term parametric stability is non-negotiable.

FAQ
What is the maximum supply voltage rating for the TLE2071AMFKB?
The TLE2071AMFKB has an absolute maximum supply voltage of ±19 V, with recommended operation from ±2.25 V to ±19 V. This allows direct integration into legacy ±15 V systems while supporting extended dynamic range in new designs. Operation beyond ±19 V risks permanent damage, and the device includes internal protection diodes to clamp transients within safe limits.
Does the TLE2071AMFKB require external compensation for unity-gain stability?
No, the TLE2071AMFKB is internally compensated for unity-gain stability. It achieves stable operation with closed-loop gains ≥1 without external capacitors or resistors. This simplifies circuit design for buffer, inverter, and active filter configurations-verified by 56° phase margin at unity gain with 25 pF load and 2 kΩ source impedance per the datasheet.
How is offset voltage adjusted on the TLE2071AMFKB?
The TLE2071AMFKB provides dedicated Offset Null 1 (Pin 12) and Offset Null 2 (Pin 13) terminals. A 10 kΩ potentiometer is connected between these pins, with its wiper tied to VCC−, enabling precise adjustment of input offset voltage down to <50 µV. This feature is critical for zero-error DC-coupled applications like precision integrators and weigh-scale amplifiers.
What is the input bias current specification for the TLE2071AMFKB at 125°C?
At +125°C, the TLE2071AMFKB maintains a maximum input bias current of 60 nA (per the TLE2071AM specification). This is significantly lower than bipolar-input op-amps and ensures minimal voltage error across high-value feedback networks-essential for thermocouple amplifiers and high-impedance sensor interfaces operating in hot environments.
Is the TLE2071AMFKB pin-compatible with other TLE207x variants in the LCCC-20 package?
Yes, all TLE207x and TLE207xA devices in the FK (LCCC-20) package-including TLE2071M, TLE2071AM, TLE2072AMFK, and TLE2074AMFK-share identical pinouts and mechanical footprints. This allows drop-in replacement within the same family for performance upgrades (e.g., A-grade offset) or temperature grade changes without PCB redesign.
