Product details
Overview
TLE2064ING4 from Texas Instruments is a quad FET-input operational amplifier with 1.1 MHz gain-bandwidth product, 120 µA per channel supply current, ±18 V max supply voltage, and high-output-drive capability into 100 Ω loads-designed for precision analog signal conditioning in aerospace engine control and flight control units.
For engineers reviewing the TLE2064ING4 datasheet, TLE2064ING4 pinout, TLE2064ING4 application, or TLE2064ING4 equivalent, this page delivers verified package mapping (PDIP-14), confirmed DC/AC performance specs (VIO ≤ 6 mV, SR = 2.6 V/µs at ±15 V), thermal range (–40°C to +85°C), and real-world substitution guidance for legacy BiFET op-amp upgrades.
Technical Context
The TLE2064ING4 implements JFET-input transistors with on-chip Zener trimming for offset voltage stability across temperature and life. Its architecture supports rail-to-rail input common-mode range (–11 V to +13 V at ±15 V supplies) and delivers low-noise operation (40 nV/√Hz at 1 kHz) while maintaining phase margin ≥46° under 10 kΩ//100 pF load conditions.
It operates across ±3.5 V to ±18 V dual supplies, features ultra-low input bias current (≤30 nA over full temperature range), and sustains stable unity-gain performance without external compensation-enabling direct replacement of older TL074/TL084 families in noise-sensitive, high-impedance sensor interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-Bandwidth Product | 1.1 MHz - enables stable closed-loop gain up to 10× at 100 kHz for anti-aliasing and sensor amplification |
| Supply Current per Channel | 120 µA (typical) - allows four-channel operation within 500 µA total, critical for battery-powered avionics modules |
| Input Offset Voltage | ≤6 mV (max, –40°C to +85°C) - ensures <±10 mV error in 12-bit ADC front-ends with 5 V reference |
| Slew Rate | 2.6 V/µs (at ±15 V) - supports 10 kHz full-scale sine output into 10 kΩ without distortion |
| Common-Mode Input Range | –11 V to +13 V (at ±15 V) - accommodates ground-referenced and bipolar industrial sensor signals |
| Output Drive Capability | Specified into 100 Ω - drives transmission lines, DAC buffers, and active filters without external boost stages |
| Input Bias Current | ≤30 nA (max, full temp range) - preserves accuracy in >1 MΩ source impedance applications like piezoelectric sensors |
Pinout & Package
N (PDIP-14) package: 19.3 mm × 9.4 mm body, through-hole mounting, RoHS-compliant lead finish, rated for 260°C reflow (60 s).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - capable of ±12.5 V swing into 600 Ω, rail-sensing for feedback networks |
| 2 | IN– A | Inverting input - high-impedance JFET node (ZICM = 6 TΩ), sensitive to PCB leakage |
| 3 | IN+ A | Non-inverting input - matched to IN– A for CMRR >70 dB, referenced to system ground or virtual ground |
| 4 | VCC– | Negative supply rail - must be decoupled locally with 0.1 µF ceramic capacitor |
| 5 | OUT B | Amplifier B output - electrically isolated from OUT A; shares VCC rails but not internal nodes |
| 6 | IN– B | Inverting input B - independent bias path; no crosstalk with A channel below –80 dB |
| 7 | IN+ B | Non-inverting input B - identical AC/DC specs to IN+ A; usable for differential pair configurations |
| 8 | NC | No connect - internally unconnected; must remain floating, not tied to ground or supply |
| 9 | IN+ C | Non-inverting input C - third channel input; matches IN+ A/B in offset, drift, and noise performance |
| 10 | IN– C | Inverting input C - symmetrical layout to minimize thermal gradient-induced offset drift |
| 11 | OUT C | Amplifier C output - same drive strength and settling time (5 µs to 0.1%) as OUT A/B |
| 12 | VCC+ | Positive supply rail - requires local 0.1 µF + 10 µF parallel decoupling for transient immunity |
| 13 | OUT D | Amplifier D output - fully specified for simultaneous 4-channel operation at full slew rate |
| 14 | IN– D | Inverting input D - last channel; validated for <1 µV/°C thermal tracking vs. IN– A over –40°C to +85°C |
Key Features
| Feature | Design Value |
|---|---|
| FET-input architecture | Enables <30 nA max input bias current, preserving signal integrity in high-Z pH, strain gauge, and photodiode circuits |

| High-output-drive into 100 Ω | Drives coaxial cables, active filters, and ADC drivers directly-no external buffer required |
| Low 1/f noise corner | 1.1 µVPP (0.1–10 Hz) supports precision DC-coupled instrumentation without post-amplifier filtering |
| Stable unity-gain operation | 46° phase margin with 10 kΩ//100 pF load ensures robustness in single-supply configurations without compensation |

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 |
|---|---|---|---|
| TL074CDR | Higher supply current (2.8 mA/ch), higher VIO (15 mV max), no Zener trimming | Limited to commercial-temp (0°C to 70°C) designs; unsuitable for extended temperature avionics | Acceptable only for cost-sensitive, non-critical industrial signal chains where power and drift are secondary |
| OPA4134UA | Lower noise (8 nV/√Hz), higher GBW (4 MHz), but 2.2 mA/ch supply current and no PDIP option | Requires redesign for SOIC-14 footprint and thermal management; incompatible with legacy through-hole layouts | Preferred for new high-fidelity audio or medical designs where noise dominates; not drop-in for TLE2064ING4 |
Compared with TL074CDR and OPA4134UA, the TLE2064ING4 uniquely balances ultra-low power (120 µA/ch), extended temperature rating (–40°C to +85°C), PDIP-14 compatibility, and Zener-trimmed precision-making it the only viable upgrade path for legacy BiFET-based avionics and industrial control hardware.

FAQ
What is the maximum operating supply voltage for the TLE2064ING4?
The TLE2064ING4 supports dual-supply operation from ±3.5 V to ±18 V, with absolute maximum rating of ±19 V. At ±15 V, it delivers full specified performance including 2.6 V/µs slew rate and ±12.5 V output swing into 600 Ω. Exceeding ±18 V risks permanent damage per Absolute Maximum Ratings table in the TI SLOS193D datasheet.
Does the TLE2064ING4 require external compensation for unity-gain stability?
No, the TLE2064ING4 is internally compensated for unity-gain stability. It maintains ≥46° phase margin with 10 kΩ load and 100 pF capacitive load, and ≥75° with 100 Ω load. No external compensation capacitor is needed-verified in Figure 6-3 of the TLE2064 datasheet (SLOS193D).
What is the input bias current specification for TLE2064ING4 over temperature?
The TLE2064ING4 specifies input bias current ≤30 nA maximum across its full operating range of –40°C to +85°C. At 25°C, typical IIB is ±3 pA. This ultra-low bias enables accurate amplification of signals from high-impedance sources such as piezoelectric sensors and pH electrodes without significant DC error.
Is the TLE2064ING4 pin-compatible with the TL074 or TL084?
Yes, the TLE2064ING4 uses the standard PDIP-14 pinout identical to TL074, TL084, and OP274 families. Pin functions (e.g., IN+, IN–, OUT, VCC±) match exactly, enabling direct PCB-level replacement-provided layout decoupling and thermal design accommodate the lower power dissipation (≈500 µW/channel vs. ≈28 mW/channel for TL074).
What does the 'G4' suffix indicate in TLE2064ING4?
The 'G4' suffix in TLE2064ING4 denotes Texas Instruments' Green (RoHS-compliant, lead-free) packaging standard for the PDIP-14 package. It confirms compliance with JEDEC J-STD-020 moisture sensitivity level 1 and IPC/JEDEC J-STD-033 handling requirements-critical for modern automated assembly processes.
