Product details
Overview
TLE2064BMJ 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 only 120μA per channel, and features low input bias current (3pA typ) and low noise (40nV/√Hz at 1kHz). It is used in flight control units and analog input modules requiring precision, stability, and wide temperature operation.
For engineers reviewing the TLE2064BMJ datasheet, TLE2064BMJ pinout, TLE2064BMJ application, or TLE2064BMJ equivalent, this page provides verified specifications, ceramic DIP-14 package details, real-world use cases in safety-critical aerospace systems, and validated alternative options for design continuity and sourcing flexibility.
Technical Context
The TLE2064BMJ implements a JFET-input stage with Zener-trimmed offset voltage, enabling stable DC precision across its full military-grade temperature range (–55°C to +125°C). Its architecture supports rail-to-rail output swing into 600Ω (±12.5V at ±15V supply) and maintains 1.1MHz unity-gain bandwidth with 2.6V/µs slew rate under ±15V operation.
It achieves high common-mode rejection (72dB min) and supply-voltage rejection (75dB min), with input resistance >1TΩ and input capacitance of 4pF. The device is optimized for low-power, high-precision signal conditioning where input impedance, long-term drift (0.04μV/month), and output drive capability are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±3.5V to ±18V - supports dual-rail industrial and aerospace power rails without level-shifting. |
| Gain-Bandwidth Product | 1.1MHz - enables stable closed-loop operation up to ~100kHz with moderate gain (e.g., AV = 10). |
| Input Bias Current | 3pA typical - preserves signal integrity in high-impedance sensor interfaces (e.g., piezoelectric, pH electrodes). |
| Output Drive Capability | Specified into 100Ω loads - delivers ±2.5V swing at ±5V supply and ±12.5V at ±15V supply into 600Ω. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar FET-input op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA4134SM | Lower noise (8nV/√Hz), higher GBW (4MHz), but rated only to +85°C and no Zener trimming; SOIC-14 only. | Not qualified for –55°C operation or avionics use; better suited for commercial audio or test equipment. | Select when wide bandwidth and ultra-low noise outweigh temperature range and long-term drift requirements. |
| LMC6084IMX | CMOS input (fA-level bias), rail-to-rail output, but lower output drive (600Ω min load) and 1.3MHz GBW; rated to +125°C but not –55°C. | Lacks military-grade cold-temperature qualification and high-current drive into low-Z loads. | Prefer for low-power, single-supply, high-impedance sensor nodes where output swing headroom is constrained. |
Compared with OPA4134SM and LMC6084IMX, the TLE2064BMJ uniquely combines military-grade temperature range, Zener-trimmed offset stability, and robust 100Ω load drive - making it irreplaceable in flight-critical signal chains where parameter guarantees across –55°C to +125°C are non-negotiable.

FAQ
What is the maximum operating temperature range for the TLE2064BMJ?
The TLE2064BMJ is rated for continuous operation from –55°C to +125°C, meeting MIL-PRF-38535 requirements for high-reliability ceramic DIP packages. Electrical specifications including input offset voltage, supply current, and output swing are guaranteed across this full range, making it suitable for engine-mounted or avionics bay deployments where ambient extremes are routine.
Does the TLE2064BMJ support dual-supply operation?
Yes, the TLE2064BMJ supports true dual-supply operation from ±3.5V to ±18V. Its input common-mode range extends to within 1.6V of either rail at ±5V supply and within 11V at ±15V supply, while output swing reaches ±12.5V into 600Ω under ±15V conditions - enabling flexible interface with both legacy and modern bipolar signal chains.
How does the Zener trimming in the TLE2064BMJ improve performance over standard TLE2064 variants?
Zener trimming in the TLE2064BMJ reduces initial input offset voltage to ≤3.1mV (max) at 25°C and limits long-term drift to 0.04μV/month - significantly tighter than untrimmed versions. This enables high-accuracy, maintenance-free operation in systems where periodic calibration is impractical, such as sealed flight control hardware or remote industrial monitors.
Can the TLE2064BMJ drive a 100Ω load effectively?
Yes - the TLE2064BMJ is explicitly characterized for high-output-drive performance into 100Ω loads. At ±5V supply, it delivers ±2.5V output swing into 100Ω; at ±15V, it sustains ±12.5V into 600Ω and remains stable driving low-impedance cables or active filters without external buffers - a key differentiator versus general-purpose op-amps.
What package type is used for the TLE2064BMJ, and why is it significant?
The TLE2064BMJ uses a ceramic dual-in-line package (CDIP-14, J suffix), measuring 19.56mm × 6.67mm. This hermetically sealed package provides superior moisture resistance, thermal stability, and long-term reliability compared to plastic alternatives - essential for aerospace, defense, and downhole applications where field failure is unacceptable.
