Product details
Overview
TLE2064CNG4 from Texas Instruments is a quad FET-input operational amplifier with 36V supply capability, 1.1MHz gain-bandwidth product, 120μA per channel supply current, ±13.7V output swing into 10kΩ at ±15V supplies, and specified high-output-drive performance into 100Ω loads. It serves precision analog signal conditioning in aerospace engine control and flight control units where low power, high voltage, and rail-to-rail input (–11V to +13V CMVR) are critical.
For engineers reviewing the TLE2064CNG4 datasheet, TLE2064CNG4 pinout, TLE2064CNG4 application, or TLE2064CNG4 equivalent, this page delivers verified electrical specifications, PDIP-14 package details, real-world use cases in safety-critical avionics subsystems, and validated alternative options for design continuity and sourcing flexibility.
Technical Context
The TLE2064CNG4 uses JFET-input transistors with on-chip Zener trimming for DC precision, delivering low input bias current (±10pA typ), high common-mode rejection (72dB min), and 93dB supply-voltage rejection at ±15V. Its 2.6V/µs slew rate and 40kHz full-swing bandwidth support dynamic signal acquisition without phase distortion in closed-loop sensor interfaces.
Designed for operation across ±3.5V to ±18V supplies, it maintains stable unity-gain phase margin (46°) with 100pF capacitive load and exhibits low 1/f noise (70nV/√Hz at 10Hz), making it suitable for low-frequency precision amplification where thermal drift and long-term offset stability matter.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-Bandwidth Product | 1.1MHz - Enables stable unity-gain configuration up to ~1MHz with adequate phase margin. |
| Supply Current per Channel | 120μA (typ) - Supports ultra-low-power operation in battery-backed or energy-constrained avionics modules. |
| Input Offset Voltage | 3mV (max, C-suffix, 0°C to 70°C) - Ensures <±1.5mV error in 12-bit ADC front-end applications at room temperature. |
| Output Swing (±15V) | ±13.7V into 10kΩ - Delivers >91% of rail-to-rail swing, minimizing headroom loss in high-voltage signal chains. |
| Common-Mode Input Range | –11V to +13V (at ±15V supply) - Accepts inputs beyond ground, enabling direct interfacing with bipolar sensor outputs. |
| Slew Rate | 2.6V/µs (typ, ±15V) - Sustains 10kHz full-scale sine wave output without slewing distortion at 10Vpp. |
| Input Bias Current | ±10pA (typ, 25°C) - Minimizes voltage error across high-impedance source networks (e.g., piezoelectric sensors). |

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 |
|---|---|---|---|
| TLE2064CDR | Same die, SOIC-14 package; 8.65mm × 6mm footprint, surface-mount only. | Preferred for automated PCB assembly; lacks through-hole mechanical robustness for high-vibration environments. | Select TLE2064CDR when board space is constrained and reflow compatibility is required. |
| TL074CP | Higher supply current (1.4mA/ch), lower GBW (3MHz), no guaranteed 100Ω drive spec. | Acceptable for non-critical general-purpose amplification but unsuitable for high-fidelity sensor conditioning or low-power designs. | Choose TL074CP only for cost-sensitive, non-precision applications where power and drive capability are secondary. |
Compared with TLE2064CNG4, TLE2064CDR offers identical electrical performance in a smaller surface-mount package ideal for density-optimized layouts, while TL074CP trades off power efficiency, output drive, and noise performance for broader availability and lower unit cost in non-avionics contexts.

FAQ
What is the maximum supply voltage rating for the TLE2064CNG4?
The TLE2064CNG4 has an absolute maximum supply voltage rating of 38V (VCC+ − VCC−), with recommended operation from ±3.5V to ±18V. Exceeding ±18V risks exceeding safe operating area limits and may degrade long-term reliability, especially at elevated temperatures. The device is rated for continuous operation at ±15V with full specification compliance.
Does the TLE2064CNG4 support rail-to-rail input or output operation?
The TLE2064CNG4 does not provide rail-to-rail input or output operation. Its common-mode input voltage range extends from –11V to +13V at ±15V supplies, and its output swing reaches ±13.7V into 10kΩ-approximately 91% of the supply rails. It cannot accept inputs at VCC– or VCC+, nor can it drive outputs to either rail under load.
What is the typical input bias current of the TLE2064CNG4 at 25°C?
The typical input bias current of the TLE2064CNG4 is ±10pA at 25°C, with a maximum of 2nA over the full 0°C to 70°C operating range. This ultra-low bias current stems from its JFET-input architecture and enables accurate amplification of signals from high-impedance sources such as piezoelectric sensors or photodiodes without significant loading error.
Can the TLE2064CNG4 drive a 100Ω load while maintaining specified AC performance?
Yes-the TLE2064CNG4 is explicitly characterized and specified for high-output-drive operation into 100Ω loads. At ±15V supply, it delivers ±12.5V minimum output swing into 600Ω and maintains full slew rate and bandwidth performance under these conditions, making it suitable for driving coaxial cables, ADC input buffers, or low-impedance filters without external gain stages.
How does the TLE2064CNG4 differ from the TLE2064M variant?
The TLE2064CNG4 is the commercial-grade (C-suffix) version rated for 0°C to 70°C operation in PDIP-14 packaging, while the TLE2064M is the military-grade (M-suffix) variant qualified for –55°C to +125°C operation in ceramic packages (J, FK). The M-suffix part features tighter offset voltage drift (0.04μV/month) and enhanced long-term reliability testing but shares identical core electrical specs including GBW, slew rate, and noise performance at 25°C.
