Product details
Overview
TLE2064ID from Texas Instruments is a quad FET-input operational amplifier optimized for high-output-drive, low-power, and wide-bandwidth analog signal conditioning in industrial and aerospace systems. It delivers 1.1 MHz gain-bandwidth, 120 μA per channel supply current, ±18 V max supply voltage, and specified output drive into 100 Ω loads-enabling precision sensor interfacing and analog input modules.
For engineers reviewing the TLE2064ID datasheet, TLE2064ID pinout, TLE2064ID application, or TLE2064ID equivalent, this page provides verified package mapping (SOIC-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 flight control unit and engine management designs.
Technical Context
The TLE2064ID uses JFET-input transistors with on-chip Zener trimming for offset voltage stability across temperature. Its high slew rate (2.6 V/µs) and 1.1 MHz GBW support fast settling in closed-loop configurations while maintaining low noise (40 nV/√Hz at 1 kHz) and high CMRR (72 dB).
Designed for rail-to-rail compatible operation within ±3.5 V to ±18 V supplies, it features robust common-mode input range (–11 V to +13 V at ±15 V), low input bias current (±10 pA typ), and open-loop output impedance of 575 Ω-making it suitable for high-impedance source buffering and active filter stages.

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 |
|---|---|---|---|
| TLE2064CD | Same architecture, but rated for 0°C to 70°C commercial temp range and higher VIO (6 mV max) | Limited to non-automotive/non-industrial ambient environments; unsuitable for engine bay or outdoor enclosures | Select when operating temperature stays within 0–70°C and cost sensitivity outweighs extended thermal margin |
| TL074CD | Lower GBW (3 MHz), higher supply current (1.4 mA/ch), no 100 Ω drive spec, wider VIO range (10 mV max) | Not qualified for safety-critical flight or engine control; lacks guaranteed output drive into low-Z loads | Choose only for general-purpose lab equipment or non-critical signal conditioning where power and drive are less constrained |
Compared with TLE2064CD and TL074CD, the TLE2064ID offers guaranteed industrial temperature operation (–40°C to +85°C), lower quiescent current (120 μA vs 1.4 mA), and validated 100 Ω load drive-making it uniquely suited for embedded control systems requiring long-term stability and robustness.

FAQ
What is the maximum supply voltage rating for the TLE2064ID?
The TLE2064ID supports a maximum supply voltage of ±18 V across its VCC+ and VCC– pins. This rating applies over the full operating temperature range of –40°C to +85°C and allows compatibility with standard ±15 V industrial rails while providing margin for transient events. Absolute maximum ratings prohibit exceeding 38 V total supply differential.
Does the TLE2064ID support operation with single-supply configurations?
Yes, the TLE2064ID can operate from a single supply, provided the common-mode input voltage remains within its specified range (e.g., –1.6 V to +4 V at ±5 V supplies). When using single-ended supplies, biasing the IN+ pins to mid-rail and ensuring output swing stays within VOH/VOL limits is required. The device does not feature rail-to-rail input or output, so design margins must be maintained.
What is the guaranteed input offset voltage specification for TLE2064ID over temperature?
The TLE2064ID guarantees a maximum input offset voltage of 6 mV over its full operating temperature range of –40°C to +85°C. This value is confirmed in the "TLE2064I Electrical Characteristics" section of the datasheet (Table 5.31), and reflects worst-case performance including initial tolerance and thermal drift-critical for precision DC-coupled applications like sensor front-ends.
Is the TLE2064ID pin-compatible with other devices in the TLE206x family?
Yes, the TLE2064ID is pin-compatible with all TLE2064x variants in the SOIC-14 (D) package, including TLE2064CD, TLE2064AD, and TLE2064BD. Pin assignments, electrical behavior, and thermal characteristics are identical across these variants-the only differences lie in temperature grade, input offset voltage binning, and long-term reliability testing. No PCB redesign is needed when upgrading from CD to ID grade.
What decoupling capacitance is recommended for the TLE2064ID power pins?
A minimum of 0.1 µF ceramic capacitor is recommended between VCC+ and VCC– pins, placed as close as possible to the SOIC-14 package. For systems with high-frequency noise or fast-switching loads, adding a 10 µF tantalum or aluminum electrolytic capacitor in parallel improves low-frequency stability. TI's datasheet Figure 7-2 confirms this dual-capacitor approach suppresses supply-induced oscillation and enhances PSRR above 10 kHz.
