Product details
Overview
TLE2064BMJB from Texas Instruments is a quad FET-input operational amplifier with JFET input stage, ±3.5V to ±18V supply range, 1.1MHz gain-bandwidth product, 2.2V/µs slew rate (±5V), and specified high-output drive into 100Ω loads. It delivers low 120µA/channel quiescent current and operates across –55°C to +125°C for aerospace and engine control signal conditioning.
For engineers reviewing the TLE2064BMJB datasheet, TLE2064BMJB pinout, TLE2064BMJB application, or TLE2064BMJB equivalent, key selection criteria include its ceramic DIP-14 package, JFET-input ultra-low bias current (<30nA max), wide common-mode range (–11V to +13V at ±15V supplies), and guaranteed performance under extended temperature extremes without derating.
Technical Context
The TLE2064BMJB implements a JFET-input differential pair with on-chip Zener trimming for offset voltage calibration, enabling stable DC precision in high-impedance sensor interfaces. Its architecture supports rail-to-rail output swing capability (±13V into 10kΩ at ±15V) while maintaining 72dB CMRR and 75dB PSRR over full temperature range.
Designed for demanding analog signal paths, it features low 1fA/√Hz input noise current and 40nV/√Hz input voltage noise at 1kHz, with phase margin of 58° at unity gain into 10kΩ//100pF - ensuring stability in closed-loop configurations without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±3.5V to ±18V - supports dual-rail industrial and avionics power domains without level-shifting. |
| Gain-Bandwidth Product | 1.1MHz - enables stable unity-gain buffering and low-frequency filtering up to ~100kHz with 40dB open-loop gain. |
| Slew Rate | 2.2V/µs (±5V), 2.6V/µs (±15V) - sufficient for 10kHz full-scale sine output with <0.1% distortion into 10kΩ. |
| Input Bias Current | ≤30nA (max, –55°C to +125°C) - preserves accuracy in high-Z pH, thermocouple, and piezoelectric sensor front-ends. |
| Input Offset Voltage | ≤3.1mV (TLE2064BM, 25°C), ≤6mV (full temp range) - enables µV-level DC-coupled amplification with minimal nulling circuitry. |
| Common-Mode Range | –11V to +13V (at ±15V supplies) - accommodates signals beyond rails in motor current sensing and battery monitoring. |
| Output Drive | Specified into 100Ω - delivers >±2.5V swing into low-impedance loads like ADC drivers or line drivers without external buffers. |

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 |
|---|---|---|---|
| OPA4134UA | Higher 8MHz GBW, lower 8nV/√Hz noise, but only rated to +85°C and uses SOIC-14. | Not qualified for extended temperature or hermetic packaging requirements. | Select when bandwidth and noise dominate over temperature range and reliability. |
| LMC6084IM | CMOS input (fA bias), rail-to-rail output, but only ±8V max supply and no military temp grade. | Lacks high-voltage operation and extended temperature support required in engine control. | Prefer for low-voltage, low-power portable instrumentation where rail-to-rail swing is essential. |
Compared with OPA4134UA and LMC6084IM, the TLE2064BMJB uniquely combines JFET-input precision, ±18V operation, hermetic CDIP-14 packaging, and full –55°C to +125°C qualification - making it irreplaceable in safety-critical aerospace signal chains where long-term parametric stability and environmental resilience are non-negotiable.

FAQ
What is the maximum operating temperature range for the TLE2064BMJB?
The TLE2064BMJB is fully specified from –55°C to +125°C per MIL-PRF-38535 Class B requirements. All electrical parameters - including input offset voltage, bias current, and slew rate - are guaranteed across this full range without derating, making it suitable for jet engine compartments and space-constrained avionics bays.
Does the TLE2064BMJB support single-supply operation?
The TLE2064BMJB is designed for dual-supply operation (±3.5V to ±18V) and does not support true single-supply use. Its input common-mode range extends to within 1.6V of the negative rail at ±5V supplies, but operation with V– = 0V violates the absolute maximum rating for differential input voltage and risks latch-up or parametric degradation.
What package type is used for the TLE2064BMJB and why is it significant?
The TLE2064BMJB uses a ceramic dual-in-line package (CDIP-14, JEDEC MS-001). This hermetically sealed package provides superior moisture resistance, thermal cycling endurance, and long-term parameter stability versus plastic packages - essential for mission-critical aerospace and defense applications where field reliability is non-negotiable.
How does the TLE2064BMJB's input bias current compare to bipolar-input op-amps?
The TLE2064BMJB's FET-input architecture delivers ≤30nA maximum input bias current over –55°C to +125°C, which is 3–4 orders of magnitude lower than typical bipolar-input op-amps (e.g., LM324: ~45nA at 25°C, but >500nA at 125°C). This enables accurate amplification of high-impedance sources like piezoelectric sensors without signal loss or DC error.
Is the TLE2064BMJB pin-compatible with other TLE2064 variants?
Yes, all TLE2064 variants - including TLE2064BMJB, TLE2064M, TLE2064AM, and TLE2064 - share identical pinouts in the CDIP-14 (J) package. The "BM" suffix denotes the B-grade offset voltage (≤3.1mV at 25°C) and military temperature qualification, while pin function and physical layout remain consistent across the family.
