Product details
Overview
TLE2072MFKB from Texas Instruments is a dual-channel, JFET-input operational amplifier optimized for high-voltage, low-noise, high-speed precision applications. It delivers ±19V supply rails, 10MHz unity-gain bandwidth, 32V/μs slew rate, and 17nV/√Hz input voltage noise at 1kHz - enabling accurate signal conditioning in oscilloscopes, flight control units, and electricity meters.
For engineers reviewing the TLE2072MFKB datasheet, TLE2072MFKB pinout, TLE2072MFKB application, or TLE2072MFKB equivalent, this page provides verified specifications, LCCC-20 package terminal mapping, real-world use cases, and validated alternative options for aerospace-grade analog front-ends and industrial measurement systems.
Technical Context
The TLE2072MFKB employs JFET-input transistors with on-chip Zener trimming for DC precision and wide dynamic range. Its architecture supports rail-to-rail differential input operation up to ±19V supplies and maintains stability with unity-gain configurations.
It achieves low 17nV/√Hz noise floor and high 32V/μs slew rate without sacrificing DC accuracy - key for fast transient capture in data acquisition and low-distortion amplification in portable test equipment.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

| Supply Voltage Range | ±2.25V to ±19V - supports wide dynamic signal range in high-voltage industrial sensors and power electronics monitoring. |
| Unity-Gain Bandwidth | 10.6MHz - ensures stable AC response up to audio and low-MHz frequencies without external compensation. |
| Slew Rate | 32V/μs - preserves fidelity of fast step inputs in oscilloscope vertical amplifiers and pulse conditioning circuits. |
| Input Voltage Noise | 17nV/√Hz at 1kHz - minimizes added noise in precision sensor interfaces and low-level signal amplification stages. |

Pinout & Package
LCCC-20 ceramic package (FK), 8.89mm × 8.89mm, hermetically sealed, leadless, surface-mountable with solder reflow compatibility per MIL-STD-883 Method 1012.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 17, 18, 19, 20 | No Connect (NC) | Unused internal terminals; must remain unconnected per TI design - no tie-to-ground or pull-up required. |
| 5, 6 | Offset Null 1 / Offset Null 2 | Adjustment pins for fine-tuning input offset voltage; used with external potentiometer for <1mV residual error. |
| 7, 16 | Inverting Input (1IN– / 2IN–) | Differential input nodes accepting signals referenced to common-mode range up to supply rails. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA211AIDRCT | Lower 1.1nV/√Hz noise but ±18V max supply; SOIC-8 only; no offset null pins. | Better for ultra-low-noise audio or medical EEG; unsuitable for >±18V or offset-adjusted industrial calibrations. | Select when noise dominates over supply range and offset trim is unnecessary. |

FAQ
What is the maximum supply voltage rating for the TLE2072MFKB?
The TLE2072MFKB supports a total supply voltage (VCC+ to VCC−) of up to 38V, enabling operation from ±2.25V to ±19V. This allows direct interfacing with high-voltage sensor bridges and industrial signal sources without external level shifting. Absolute maximum ratings specify 38V - exceeding this risks permanent damage.
Does the TLE2072MFKB require external compensation for unity-gain stability?
No, the TLE2072MFKB is internally compensated and unity-gain stable. It achieves 56° phase margin at unity gain with 25pF capacitive load and 2kΩ load resistance, eliminating need for external compensation networks. This simplifies layout and improves reliability in high-density PCBs used in oscilloscopes and flight control hardware.
How does the TLE2072MFKB's offset null functionality work?
The TLE2072MFKB provides dedicated Offset Null 1 and Offset Null 2 pins (pins 5 and 6) for each amplifier channel. A 20kΩ potentiometer connected between these pins with its wiper to VCC− adjusts input offset voltage to <1mV. This feature is critical for zero-error calibration in electricity meters and precision DMM front-ends where auto-zero circuitry is impractical.
Is the TLE2072MFKB compatible with lead-free reflow processes?
Yes, the TLE2072MFKB LCCC-20 package is qualified for lead-free reflow per JEDEC J-STD-020, with peak reflow temperature up to 260°C for 10 seconds. Its ceramic construction and gold-plated terminations ensure robust solder joint integrity and thermal cycling reliability in aerospace and defense assemblies.
What is the typical input capacitance of the TLE2072MFKB?
The TLE2072MFKB exhibits 11pF common-mode and 2.5pF differential input capacitance at 25°C. These values impact stability in high-frequency photodiode transimpedance configurations and require careful PCB layout - including guard rings and minimized trace length - to avoid oscillation in sensitive analog front-ends using the TLE2072MFKB.
