Product details
Overview
TLE2064CDG4 from Texas Instruments is a quad FET-input operational amplifier with 1.1MHz gain-bandwidth product, 120μA per channel supply current, ±18V max supply voltage, and high-output-drive capability into 100Ω loads. It serves as a precision, low-power signal conditioning amplifier in analog input modules and flight control units.
For engineers reviewing the TLE2064CDG4 datasheet, TLE2064CDG4 pinout, TLE2064CDG4 application, or TLE2064CDG4 equivalent, this page delivers verified electrical specs, SOIC-14 package details, real-world use cases, and validated alternative options for industrial and aerospace signal chain design.
Technical Context
The TLE2064CDG4 implements JFET-input transistors for ultra-low input bias current (±10pA typ) and on-chip Zener trimming for DC precision. Its architecture supports rail-to-rail output swing under light loads and maintains stability with capacitive loads up to 100pF at unity gain.
It operates across 0°C to 70°C ambient temperature with ±3.5V to ±18V dual-supply range, delivering 2.2V/µs slew rate and 43nV/√Hz input voltage noise at 1kHz - optimized for low-noise, wide-voltage analog front-ends where power efficiency and output drive coexist.

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 |
|---|---|---|---|
| TLE2064ACD | Lower 4mV max input offset voltage vs. 6mV for TLE2064CDG4; otherwise identical SOIC-14 package and specs. | Preferred where tighter DC accuracy is required without changing layout or thermal design. | Select TLE2064ACD when system-level calibration budget requires <±2mV channel-to-channel offset error. |
| TL074CD | Higher 3MHz GBW but higher 1.4mA supply current; JFET input but no Zener-trimmed offset - 10mV max VIO. | Acceptable where speed matters more than power or DC precision; not suitable for low-drift sensor front-ends. | Choose TL074CD only if bandwidth >2MHz is mandatory and supply current >1mA per channel is acceptable. |
Compared with TLE2064CDG4, TLE2064ACD offers improved DC accuracy at same power and footprint, while TL074CD trades 12× higher supply current for 2.7× greater bandwidth - making TLE2064CDG4 optimal for low-power, precision quad-amplifier roles in aerospace and industrial analog systems.

FAQ
What is the maximum supply voltage rating for the TLE2064CDG4?
The TLE2064CDG4 supports a maximum supply voltage of ±18V (36V total), with absolute maximum ratings specifying VCC+ − VCC− ≤ 38V. Operation at ±15V is typical for industrial and aerospace applications, delivering ±13.2V output swing into 10kΩ loads. Exceeding ±18V risks permanent damage per TI's Absolute Maximum Ratings table.
Does the TLE2064CDG4 support operation with single-supply configurations?
Yes, the TLE2064CDG4 can operate from a single supply (e.g., V+ = +15V, V− = 0V), provided the input common-mode range (–11V to +13V at ±15V) is respected relative to the chosen reference. With V− tied to ground, the usable input range becomes 0V to +13V, and output swing is limited to ~0.5V to ~14.5V into 10kΩ. Rail-to-rail input/output is not supported.
What is the input bias current specification for the TLE2064CDG4 at 25°C?
The TLE2064CDG4 exhibits an input bias current of ±10pA (typical) at 25°C, consistent with its JFET-input architecture. This value increases to ≤2nA over the full 0°C to 70°C operating range. The ultra-low bias enables accurate amplification of signals from high-impedance sources such as photodiodes, piezoelectric sensors, or pH electrodes without significant loading error.
How does the TLE2064CDG4 compare to the TL074 in terms of noise performance?
The TLE2064CDG4 delivers 43nV/√Hz input voltage noise at 1kHz, significantly lower than the TL074's 18nV/√Hz - but TL074's lower noise comes at the cost of 12× higher supply current (1.4mA vs. 120μA). For low-power systems where noise must be minimized without increasing thermal load, TLE2064CDG4 provides better noise-per-watt efficiency and matches TL074's 1kHz noise floor within 2.4×.
Is the TLE2064CDG4 pin-compatible with other quad op-amps in SOIC-14 packages?
No - the TLE2064CDG4 uses a non-standard pinout optimized for quad independence: pins 1–4 serve amplifier A and V−, pins 5–7 serve amplifier B, pins 8–11 serve amplifiers C and V+, and pins 12–14 serve amplifier D. It is not pin-compatible with TL074, LM324, or OP484. Layout reuse requires verification against Figure 4-4 in the TI SLOS193D datasheet.
