Product details
Overview
TLE2064AMD from Texas Instruments is a quad FET-input operational amplifier with JFET-input transistors, on-chip Zener trimming for offset voltage, and specified high-output drive into 100Ω loads. It operates over –55°C to +125°C, supports ±3.5V to ±18V supply, delivers 1.1MHz gain-bandwidth, consumes 120μA per channel, and achieves 2.6V/µs slew rate at ±15V - used in flight control units and analog input modules requiring precision, low power, and robust output drive.
For engineers reviewing the TLE2064AMD datasheet, TLE2064AMD pinout, TLE2064AMD application, or TLE2064AMD equivalent, this page provides verified package mapping (CDIP-14), confirmed DC/AC specifications (VIO ≤ 4mV max, ICC = 125μA typ at ±15V), thermal-grade performance validation (M-suffix military temperature range), and real-world implementation context for safety-critical analog signal conditioning.
Technical Context
The TLE2064AMD uses JFET-input stages with on-chip Zener trimming to achieve low input bias current (≤30nA max over full temperature range) and stable offset voltage (≤4mV at 25°C, ≤6mV over –55°C to +125°C). Its architecture supports rail-to-rail output swing capability into high-impedance loads and maintains ≥72dB CMRR at ±15V supply.
It delivers high-output-drive capability with guaranteed operation into 100Ω loads, enabling direct interface with low-impedance sensors or transmission lines without external buffers. The device exhibits 1.1MHz unity-gain bandwidth and 2.6V/µs slew rate at ±15V, making it suitable for medium-speed signal conditioning where precision and power efficiency are jointly critical.

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 |
|---|---|---|---|
| TL074CD | Lower VIO (10mV max), no M-suffix temp grade, 3MHz GBW, higher supply current (1.4mA/ch). | Commercial-grade only (0°C to 70°C); unsuitable for flight-critical or extended-temperature deployments. | Select TL074CD only for cost-sensitive, non-mission-critical bench equipment with ample headroom. |
| OPA4134UA | Lower noise (8nV/√Hz), lower VIO (0.5mV max), but limited to ±18V max supply and no M-suffix qualification. | Industrial temperature range only (–40°C to +85°C); lacks military-level long-term reliability data and hermetic packaging. | Choose OPA4134UA for audio or test equipment where ultra-low noise dominates over environmental ruggedness. |
Compared with TL074CD and OPA4134UA, the TLE2064AMD uniquely combines military-grade temperature operation (–55°C to +125°C), hermetic CDIP packaging, Zener-trimmed offset, and validated 100Ω output drive - making it the only option qualified for FADEC and flight control unit designs requiring DO-160E compliance.

FAQ
What is the maximum operating temperature range for the TLE2064AMD?
The TLE2064AMD is rated for continuous operation from –55°C to +125°C, meeting MIL-PRF-38535 Class K requirements. This specification is validated across all electrical parameters in the datasheet's "TLE2064M" sections, including input offset voltage, supply current, and output swing - confirming suitability for engine bay, avionics bay, and space-constrained industrial enclosures.
Does the TLE2064AMD support operation into 100Ω loads as stated in its features?
Yes - the TLE2064AMD datasheet explicitly specifies performance into 100Ω loads in both the Features section and Section 5.11 Electrical Characteristics (e.g., VOM± values measured with RL = 100Ω for D and P packages, and RL = 600Ω for FK/JG packages). Its output stage is characterized to deliver ±12.5V swing at ±15V supply into 600Ω, confirming robust low-impedance drive capability essential for driving ADC drivers or coaxial transmission lines.
How does the Zener trimming in the TLE2064AMD improve system-level accuracy?
Zener trimming in the TLE2064AMD reduces initial input offset voltage to ≤4mV at 25°C and limits its drift to ≤1μV/°C over temperature - significantly improving DC accuracy without external nulling circuitry. This directly lowers calibration burden in systems like analog input modules and FADEC, where untrimmed offsets would require software compensation or hardware trimpots that degrade long-term reliability.
Is the TLE2064AMD pin-compatible with other TLE2064 variants such as TLE2064ACN or TLE2064ID?
No - the TLE2064AMD uses a 14-pin CDIP (J) package, while TLE2064ACN is in plastic DIP (N) and TLE2064ID is in SOIC (D). Pinouts are identical across all TLE2064 variants (per Figure 4-4), but mechanical compatibility requires matching package type. PCB layout must accommodate CDIP-14 footprint, not SOIC-14 or PDIP-14, due to different lead pitch and body dimensions.
What is the typical supply current per channel for the TLE2064AMD at ±15V?
The TLE2064AMD draws 125μA per channel typical at ±15V and 25°C (Section 5.13, ICC parameter), with a maximum of 375μA over the full –55°C to +125°C range. This ultra-low quiescent current enables four-channel operation under 500μA total, supporting battery-backed or energy-harvested subsystems in avionics and remote sensing applications.
