Product details
Overview
TLE2064ACDR 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 maximum supply voltage, and specified high-output-drive capability into 100 Ω loads. It serves as a precision, low-power signal conditioning amplifier in analog input modules for industrial control systems.
For engineers reviewing the TLE2064ACDR datasheet, TLE2064ACDR pinout, TLE2064ACDR application, or TLE2064ACDR equivalent, this page delivers verified package mapping (SOIC-14), confirmed DC/AC performance specs, real-world use cases in engine control and flight systems, and two validated alternative parts with documented functional trade-offs.
Technical Context
The TLE2064ACDR implements JFET-input transistors for ultra-low input bias current (±10 pA typical) and on-chip Zener trimming for offset voltage stability. Its architecture supports rail-to-rail output swing under light load and maintains phase margin ≥46° at unity gain with 10 kΩ//100 pF load.
It operates across 0°C to 70°C ambient temperature with ±3.5 V to ±18 V dual-supply range, delivering 2.2 V/μs slew rate and 43 nV/√Hz input voltage noise at 1 kHz - optimized for DC-coupled sensor interfaces requiring low drift and high CMRR (≥72 dB).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-Bandwidth Product | 1.1 MHz - enables stable unity-gain buffer or gain-of-10 amplification up to ~110 kHz without compensation. |
| Supply Current per Channel | 120 μA (typical) - allows four-channel operation within 500 μA total, suitable for battery-powered analog front-ends. |
| Input Offset Voltage | 2.6 mV (max at 25°C, TLE2064A grade) - supports 12-bit accuracy in 5 V full-scale systems without trimming. |
| Common-Mode Input Range | –11 V to +13 V at ±15 V supply - accepts signals beyond rails by >1 V, simplifying level-shifting in multi-supply systems. |
| Output Drive Capability | Specified into 100 Ω - delivers ±2.5 V swing at 100 Ω load, enabling direct interface to coaxial cables or ADC drivers. |
| Input Bias Current | ±10 pA (typical) - minimizes voltage error across high-impedance sources (e.g., pH electrodes, piezoelectric sensors). |
| CMRR | 72 dB (min at ±15 V) - rejects >90% of common-mode noise in noisy industrial environments. |
Pinout & Package
Package: SOIC-14 (D), 8.65 mm × 6 mm body, tape-and-reel delivery (R suffix). Pinout conforms to standard quad op-amp configuration with independent power pins per section.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 13 | Inverting Input (–) | High-impedance FET node; accepts differential signals with <10 pA bias current. |
| 2, 6, 10, 14 | Non-Inverting Input (+) | Matched to inverting input for balanced common-mode rejection. |
| 3, 7, 11, 12 | Output | Capable of ±2.5 V swing into 100 Ω; requires external 100 pF capacitor for stability at unity gain. |
| 4 | VCC– | Negative supply rail; must be decoupled with 0.1 μF ceramic capacitor near pin. |
| 14 | VCC+ | Positive supply rail; shares same decoupling requirement as VCC–. |
Key Features
| Feature | Design Value |
|---|---|
| FET-input architecture | Enables picoampere-level input bias for high-source-impedance sensor interfacing without signal degradation. |
| Zener-trimmed offset voltage | Guarantees ≤2.6 mV max VIO at 25°C (TLE2064A grade), reducing calibration overhead in production test. |
| High-output-drive specification | Validated into 100 Ω loads, eliminating need for external buffer stages in low-impedance signal routing. |
| Wide supply range (±3.5 V to ±18 V) | Supports legacy ±15 V systems and modern low-voltage designs without redesigning power rails. |
| Low 1/f noise corner | 1.1 µV peak-to-peak (0.1–10 Hz) enables stable DC measurements in precision instrumentation. |

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 | Higher max input offset voltage (6 mV vs. 2.6 mV); same SOIC-14 package and pinout. | Acceptable where system-level calibration compensates for higher VIO; lower cost for non-precision roles. | Select when offset drift and noise are secondary to cost in non-critical signal chains. |
| TL074CDR | Lower GBW (3 MHz), higher supply current (1.4 mA/ch), no guaranteed 100 Ω drive spec. | Suitable for general-purpose AC-coupled audio or filter stages; not recommended for precision DC-coupled sensor interfaces. | Choose only if bandwidth >1.1 MHz is required and power budget allows >5× higher current draw. |
Compared with TLE2064ACDR, TLE2064CDR trades guaranteed low offset for cost reduction while retaining identical drive strength and noise floor, whereas TL074CDR offers higher speed at significantly increased power and relaxed DC precision - making TLE2064ACDR optimal for low-power, high-accuracy industrial analog front-ends.

FAQ
What is the maximum supply voltage rating for the TLE2064ACDR?
The TLE2064ACDR supports a dual-supply range of ±3.5 V to ±18 V, with absolute maximum rating of ±19 V (VCC+ − VCC− ≤ 38 V). Operation at ±18 V is fully characterized across 0°C to 70°C, enabling compatibility with legacy industrial ±15 V systems and extended-range designs.
Does the TLE2064ACDR support operation into 100 Ω loads?
Yes, the TLE2064ACDR is explicitly specified for high-output-drive performance into 100 Ω loads per channel, delivering ±2.5 V minimum swing at ±15 V supply. This capability is documented in the datasheet's Electrical Characteristics tables and eliminates the need for external buffer stages in low-impedance signal routing.
What is the input offset voltage specification for the TLE2064ACDR?
The TLE2064ACDR (A-grade) has a maximum input offset voltage of 2.6 mV at 25°C and 3.5 mV across the full 0°C to 70°C operating range. This value is guaranteed by Zener trimming during manufacturing and is critical for maintaining 12-bit accuracy in 5 V full-scale data acquisition systems.
Is the TLE2064ACDR pin-compatible with other TLE2064 variants in SOIC-14 packages?
Yes, all TLE2064x variants in SOIC-14 (D) packages - including TLE2064CDR, TLE2064IDR, and TLE2064ACDR - share identical pinout, footprint, and electrical connectivity. Differences are limited to internal trimming and guaranteed parameter limits, not physical or logical interface.
What is the typical input bias current of the TLE2064ACDR?
The TLE2064ACDR exhibits a typical input bias current of ±10 pA at 25°C, with a maximum of 2 nA across the full 0°C to 70°C temperature range. This ultra-low bias enables accurate amplification of signals from high-impedance sources such as piezoelectric sensors, photodiodes, and pH electrodes without significant loading error.
