Product details
Overview
TLE2064IDRG4 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 where JFET-input impedance and rail-to-rail output swing are critical.
For engineers reviewing the TLE2064IDRG4 datasheet, TLE2064IDRG4 pinout, TLE2064IDRG4 application, or TLE2064IDRG4 equivalent, this page delivers verified electrical specifications, SOIC-14 package details, real-world use cases in safety-critical avionics and engine control systems, and validated alternative options for design continuity.
Technical Context
The TLE2064IDRG4 uses JFET-input transistors for ultra-low input bias current (±10pA typical) and on-chip Zener trimming for DC precision. Its architecture supports stable unity-gain operation with 46° phase margin and delivers 2.2V/µs slew rate at ±5V supplies.
It operates across –40°C to +85°C, features 6 || 1 TΩ common-mode input resistance, and maintains 72dB CMRR at ±15V supplies - enabling accurate amplification of low-level sensor signals in noisy industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-Bandwidth Product | 1.1 MHz - enables stable closed-loop operation up to ~100 kHz with moderate gain. |
| Supply Current per Channel | 120 μA (typical) - allows battery-powered or energy-constrained systems to integrate four op-amps without excessive quiescent load. |
| Input Offset Voltage | 6 mV (max, –40°C to +85°C) - sets absolute DC accuracy limit for precision sensor front-ends. |
| Common-Mode Input Range | –11 V to +13 V at ±15 V supplies - supports direct interfacing with bipolar transducer outputs. |
| Output Drive Capability | Specified into 100 Ω loads - enables direct driving of low-impedance cables or ADC reference buffers without external buffers. |
| Slew Rate | 2.2 V/µs (typical, ±5 V) - supports clean amplification of 10 kHz sine waves with ≤0.025% THD. |
| Input Bias Current | ±10 pA (typical, 25°C) - minimizes voltage error across high-impedance source networks (e.g., pH electrodes, piezoelectric sensors). |
Pinout & Package
Package: SOIC-14 (D), 8.65 mm × 6 mm body size, surface-mount, tape-and-reel (R-suffix indicates reel packaging).

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 SOIC-14 package and electrical specs, but rated for 0°C to 70°C (C-temp) instead of –40°C to +85°C (I-temp). | Not qualified for extended temperature industrial or avionics use; limited to commercial-grade instrumentation. | Select only if operating ambient stays within 0–70°C and long-term reliability under thermal cycling is not required. |
| TL074CDR | Lower GBW (3 MHz), higher supply current (1.4 mA/ch), no guaranteed 100 Ω drive spec; JFET input retained. | Higher power consumption and less robust output stage limit use in low-power or high-current-sink applications. | Consider only when higher speed is needed and output loading is light (≥10 kΩ); verify stability with capacitive loads. |
Compared with TLE2064IDRG4, TLE2064CDR sacrifices temperature range for lower cost in benign environments, while TL074CDR trades micro-power operation and rugged output drive for increased bandwidth - making TLE2064IDRG4 uniquely suited for extended-temperature, low-power, high-drive analog signal chains.

FAQ
What is the maximum supply voltage rating for the TLE2064IDRG4?
The TLE2064IDRG4 has an absolute maximum supply voltage rating of ±18 V, with a maximum differential supply voltage (VCC+ – VCC–) of 38 V. Operation beyond these limits risks permanent damage. The device is characterized for reliable operation from ±3.5 V to ±18 V across its full –40°C to +85°C temperature range, making TLE2064IDRG4 suitable for both legacy industrial rails and modern low-voltage designs.
Does the TLE2064IDRG4 support rail-to-rail input or output operation?
The TLE2064IDRG4 does not provide rail-to-rail input or output operation. Its common-mode input voltage range is specified as –11 V to +13 V at ±15 V supplies, and output swing is typically ±13 V into 10 kΩ. However, it does deliver full-scale output into 100 Ω loads - a key differentiator versus standard rail-to-rail op-amps - enabling direct interface with low-impedance destinations without external buffers. This behavior is explicitly guaranteed in the TLE2064IDRG4 datasheet.
What is the input bias current specification for the TLE2064IDRG4 at 25°C?
The TLE2064IDRG4 exhibits an input bias current of ±10 pA (typical) at 25°C, consistent with its JFET-input architecture. Over the full –40°C to +85°C operating range, the maximum input bias current is 4 nA. This ultra-low value ensures minimal voltage error across high-impedance sources such as piezoelectric sensors, photodiode transimpedance nodes, or high-value resistor dividers - a core design advantage confirmed in the TLE2064IDRG4 electrical characteristics tables.
Is the TLE2064IDRG4 pin-compatible with other quad op-amps in SOIC-14 packages?
The TLE2064IDRG4 follows the industry-standard SOIC-14 pinout for quad op-amps (pin 1 = In– ch1, pin 2 = In+ ch1, pin 3 = Out ch1, pin 4 = V–, etc.), matching TL074, LM324, and OPA4134 layouts. However, functional compatibility requires verification of supply range, output drive, and AC performance - for example, TL074 draws 1.4 mA/ch and lacks guaranteed 100 Ω drive, while LM324 is bipolar and unsuitable for high-Z sources. Pin mapping alone does not ensure drop-in replacement; TLE2064IDRG4's unique combination of micro-power, FET input, and high-drive must be validated per application.
How does the TLE2064IDRG4 achieve low noise performance despite its micro-power design?
The TLE2064IDRG4 achieves 43 nV/√Hz input voltage noise at 1 kHz (±5 V supply) through optimized JFET input stage design and careful biasing - delivering lower noise than earlier-generation low-power BiFET amplifiers, as stated in its official features list. Its 1.1 MHz GBW and 2.2 V/µs slew rate reflect a deliberate trade-off that preserves signal fidelity in DC-coupled sensor interfaces without excessive current draw. This balance is validated in the TLE2064IDRG4 operating characteristics section, where noise, THD (0.025%), and settling time (5 µs to 0.1%) are all measured and published.
