Product details
Overview
TLE2064AMFKB from Texas Instruments is a quad FET-input operational amplifier with 1.1MHz gain-bandwidth product, 120μA per channel supply current, ±18V max supply voltage, and high-output-drive capability into 100Ω loads. It serves as a precision, low-power signal conditioning amplifier in aerospace analog input modules and flight control units where wide temperature operation and low noise are critical.
For engineers reviewing the TLE2064AMFKB datasheet, TLE2064AMFKB pinout, TLE2064AMFKB application, or TLE2064AMFKB equivalent, key selection criteria include its –55°C to +125°C operating range, JFET-input architecture enabling pA-level bias current, on-chip Zener-trimmed offset voltage (≤4.6mV max), and LCCC-20 ceramic package for high-reliability mil-aero systems.
Technical Context
The TLE2064AMFKB implements a JFET-input differential pair with on-chip Zener trimming for DC precision, delivering low input bias current (≤30nA over full temperature range) and low input offset voltage drift (1μV/°C). Its unity-gain stable architecture supports rail-to-rail output swing into 10kΩ and maintains ≥40kHz bandwidth at ±15V supply with 10kΩ load.
It operates across ±3.5V to ±18V supplies and features 72dB common-mode rejection at ±15V, 93dB supply-voltage rejection, and 2.6V/µs slew rate - optimized for high-fidelity amplification in low-power, high-voltage analog front ends without external compensation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad FET-input op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA4134SM | Lower noise (8nV/√Hz), higher GBW (4MHz), but only rated to +85°C and uses SOIC-14 | Not qualified for extended temperature or hermetic packaging requirements | Select when noise and speed dominate over temperature range and reliability |

FAQ
What is the maximum operating supply voltage for the TLE2064AMFKB?
The TLE2064AMFKB supports a maximum supply voltage of ±18V (36V total), with recommended operation between ±3.5V and ±18V. This wide supply range allows direct integration into legacy 28V aircraft power systems and high-voltage industrial sensors without external regulation. The device maintains specified performance across this range, including 72dB CMRR at ±15V.
Does the TLE2064AMFKB require external compensation for unity-gain stability?
No, the TLE2064AMFKB is internally compensated for unity-gain stability. It achieves ≥46° phase margin with 10kΩ load and 100pF capacitance, and up to 75° with 100Ω load. This eliminates external compensation components in most configurations, simplifying layout and improving reliability in space-constrained avionics PCBs where the TLE2064AMFKB is commonly deployed.
What is the input offset voltage specification for the TLE2064AMFKB over temperature?
The TLE2064AMFKB has a maximum input offset voltage of 4.6mV across its full operating range of –55°C to +125°C. This value is guaranteed due to on-chip Zener trimming, and its temperature coefficient is limited to 1μV/°C. These specifications make the TLE2064AMFKB suitable for precision applications such as engine ECU analog front ends where calibration intervals must be extended.
Is the TLE2064AMFKB pin-compatible with other TLE2064 variants in LCCC packages?
Yes, the TLE2064AMFKB shares identical pinout and footprint with all TLE2064xM variants in FK (LCCC-20) packages, including TLE2064M and TLE2064BM. Pin assignments for inputs, outputs, supplies, and NC terminals are consistent across the M-suffix LCCC family, enabling drop-in replacement within the same temperature grade and offset specification tier.
What is the output drive capability of the TLE2064AMFKB into low-impedance loads?
The TLE2064AMFKB is explicitly characterized for operation into 100Ω loads, delivering ±2.5V output swing at ±15V supply. It sustains this performance with <0.1% THD at 10kHz and maintains 2.6V/µs slew rate - enabling direct interface to coaxial cables, line drivers, or power-stage inputs without external buffers, a key advantage in compact flight control hardware using the TLE2064AMFKB.
