Product details
Overview
TLE2064BMFKB from Texas Instruments is a quad FET-input operational amplifier with 36V supply capability, 1.1MHz gain-bandwidth product, 120μA per channel supply current, ±14.9V output swing into 10kΩ at ±15V supplies, and specified high-output-drive performance into 100Ω loads. It serves precision analog signal conditioning in aerospace flight control units and engine management systems.
For engineers reviewing the TLE2064BMFKB datasheet, TLE2064BMFKB pinout, TLE2064BMFKB application, or TLE2064BMFKB equivalent, this page delivers verified electrical specifications, LCCC-20 package terminal mapping, real-world use cases in safety-critical analog input modules, and validated alternative options for extended-temperature industrial designs.
Technical Context
The TLE2064BMFKB uses JFET-input transistors with on-chip Zener trimming for offset voltage stability across –55°C to +125°C. Its architecture delivers low input bias current (≤30nA max), high common-mode rejection (≥72dB), and robust phase margin (≥58°) under unity-gain conditions with 10kΩ load and 100pF capacitance.
It operates from ±3.5V to ±18V dual supplies, supports rail-to-rail input common-mode range up to ±12V at ±15V supplies, and maintains 2.6V/µs slew rate and 40kHz full-power bandwidth into 10kΩ - enabling stable amplification of fast transient signals in high-voltage sensor interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-Bandwidth Product | 1.1MHz - enables stable closed-loop operation up to ~100kHz with moderate gain (e.g., AV = 10) in sensor front-end stages. |
| Supply Current per Channel | 120μA (typical) - allows four-channel operation within 500μA total, suitable for battery-backed or low-quiescent systems. |
| Input Offset Voltage | 1.9mV (max, TLE2064BM grade) - ensures ≤±2mV DC error in 12-bit ADC driver applications over full temperature range. |
| Output Drive Capability | Specified into 100Ω - supports direct driving of low-impedance loads such as transmission lines or power transistor bases without external buffers. |
| Common-Mode Input Range | –11V to +13V at ±15V supplies - accommodates wide-swing industrial sensor outputs (e.g., 4–20mA loop receivers). |
| Slew Rate | 2.6V/µs (typical, ±15V) - supports <10µs settling for 10V step inputs, critical for fast-response analog input modules. |
| Operating Temperature | –55°C to +125°C - qualified for military/aerospace environments including flight control unit electronics. |
Pinout & Package
The TLE2064BMFKB is housed in an FK (LCCC-20) ceramic package measuring 8.89mm × 8.89mm, with leads soldered to metallized pads on the bottom surface and no through-hole pins. It features hermetic sealing and gold-plated terminations for high-reliability applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 | IN– (Ch1–Ch4) | Inverting inputs - high-impedance JFET nodes enabling µA-level bias current and minimal loading of high-Z sources. |
| 5, 6, 7, 8 | IN+ (Ch1–Ch4) | Non-inverting inputs - support rail-to-rail common-mode operation and precise differential sensing. |
| 9, 10, 11, 12 | OUT (Ch1–Ch4) | Amplified outputs - capable of ±12.5V swing into 600Ω, enabling direct interface to downstream comparators or ADC drivers. |
| 13 | VCC+ | Positive supply rail - accepts up to +18V; decoupling required within 1cm for stability in high-speed configurations. |
| 14 | VCC– | Negative supply rail - accepts down to –18V; must be referenced to system ground via low-inductance path. |
| 15–20 | NC | No-connect terminals - electrically isolated; used for mechanical anchoring and thermal dissipation in LCCC structure. |
Key Features
| Feature | Design Value |
|---|---|

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 |
|---|---|---|---|
| TLE2064AMJ | Ceramic DIP-14 package; same electrical specs but larger footprint and through-hole mounting. | Preferred for legacy board designs requiring manual assembly or high-vibration mechanical retention. | Select when PCB layout constraints allow 19.56mm × 6.67mm area and through-hole reflow is available. |
| OPA4134UA | Lower 8nV/√Hz noise, higher 4MHz GBW, but only rated to +85°C and lacks Zener-trimmed offset. | Suitable for commercial-grade audio or test equipment, not qualified for extended-temperature aerospace use. | Choose only for non-safety-critical, lower-noise applications where –55°C operation is unnecessary. |
Compared with TLE2064AMJ and OPA4134UA, the TLE2064BMFKB uniquely combines hermetic LCCC packaging, guaranteed 1.9mV offset over –55°C to +125°C, and 100Ω drive capability - making it the sole option for new high-reliability flight control and FADEC designs requiring zero-layout change from legacy TLE206xM footprints.

FAQ
What is the maximum operating supply voltage for the TLE2064BMFKB?
The TLE2064BMFKB supports dual-supply operation from ±3.5V to ±18V, with absolute maximum rating of ±19V. At ±15V supplies, it delivers ±14.9V output swing into 10kΩ and maintains 2.6V/µs slew rate - confirming robust performance within its specified operating window. Exceeding ±18V risks permanent damage per Absolute Maximum Ratings.
Does the TLE2064BMFKB require external compensation for unity-gain stability?
No, the TLE2064BMFKB is internally compensated and stable at unity gain. Data sheet Figure 6-3 confirms ≥58° phase margin with 10kΩ load and 100pF capacitive load, and ≥75° with 100Ω load. This eliminates need for external compensation networks in standard configurations, simplifying design of precision buffer and follower circuits using the TLE2064BMFKB.
How does the input offset voltage of the TLE2064BMFKB compare to the commercial-grade TLE2064CD?
The TLE2064BMFKB has a maximum input offset voltage of 1.9mV over –55°C to +125°C, while the TLE2064CD (plastic DIP) is rated at 6mV over 0°C to 70°C. The TLE2064BMFKB's Zener-trimmed architecture and military-grade screening yield tighter DC precision across extreme temperatures - a key differentiator for systems where calibration drift must be minimized without software correction in the TLE2064BMFKB.
Can the TLE2064BMFKB drive a 600Ω load effectively?
Yes, the TLE2064BMFKB is explicitly characterized into 600Ω loads: at ±15V supplies, it delivers ±12.5V minimum output swing and maintains ≥25V/mV large-signal voltage gain. This capability is confirmed in Section 5.5 of the datasheet and enables direct interfacing with legacy instrumentation inputs, power transistor bases, and low-impedance filters - a core design feature of the TLE2064BMFKB.
What is the input bias current specification for the TLE2064BMFKB over temperature?
The TLE2064BMFKB specifies maximum input bias current of 30nA over the full –55°C to +125°C range, with typical values ≤3pA at 25°C. This ultra-low bias current stems from its JFET-input architecture and enables accurate amplification of high-impedance sources (e.g., piezoelectric sensors or pH electrodes) without significant signal attenuation - a defining characteristic of the TLE2064BMFKB.
