Product details
Overview
TLE2064CDRG4 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 TLE2064CDRG4 datasheet, TLE2064CDRG4 pinout, TLE2064CDRG4 application, or TLE2064CDRG4 equivalent, this page delivers verified package mapping (SOIC-14), confirmed DC/AC performance specs (VIO ≤ 6 mV, SR = 2.6 V/µs at ±15 V), thermal range (0°C to 70°C), and real-world substitution guidance for legacy BiFET amplifier upgrades.
Technical Context
The TLE2064CDRG4 uses JFET-input transistors with on-chip Zener trimming for offset voltage stability, delivering low input bias current (±10 pA typ) and ultra-high input impedance (6 TΩ || 1 pF common-mode). 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 ±3.5 V to ±18 V dual supplies, with common-mode input range extending to –11 V to +13 V at ±15 V supply-enabling direct interfacing with industrial sensor outputs and DACs without level-shifting circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-Bandwidth Product | 1.1 MHz - Enables stable unity-gain buffer operation up to ~1 MHz with minimal phase lag. |
| Supply Current per Channel | 120 μA (typ) - Supports battery-powered or energy-constrained systems with four independent amplifiers. |
| Input Offset Voltage | 6 mV (max, C-suffix, full temp range) - Sets worst-case DC error floor in precision gain stages. |
| Slew Rate | 2.6 V/µs (at ±15 V, 25°C) - Sustains clean 10 kHz sine wave output at 2 VPP into 10 kΩ load. |
| Common-Mode Input Range | –11 V to +13 V (at ±15 V supply) - Accepts signals beyond rails by >1 V, simplifying sensor front-end design. |
| Output Drive Capability | Specified into 100 Ω - Delivers >±2 V swing at 20 mA peak into low-impedance loads like ADC drivers or cable drivers. |
| Input Bias Current | ±10 pA (typ, 25°C) - Minimizes voltage error across high-value feedback networks (>1 MΩ). |
Pinout & Package
Package: SOIC-14 (D package), 8.65 mm × 6 mm body size, surface-mount, tape-and-reel (R suffix indicates reel packaging).

| 11 | IN+ C | Non-inverting input C - Used in multi-channel instrumentation topologies (e.g., 3-phase current sensing). |
| 12 | VCC+ | Positive supply rail - Requires local 0.1 µF ceramic decoupling to minimize PSRR degradation. |
| 13 | OUT D | Amplifier D output - Fourth channel; enables single-package quad signal conditioning without inter-chip matching errors. |

Key Features
| Feature | Design Value |
|---|---|
| FET-input architecture | Enables picoampere-level input bias current for high-impedance source interfacing (e.g., piezoelectric sensors). |
| High-output-drive specification | Guaranteed performance into 100 Ω loads ensures reliable driving of coaxial cables or ADC input buffers without external boost stages. |
| Low-noise floor vs. prior BiFET generations | 40–70 nV/√Hz input voltage noise at 1 kHz improves SNR in precision measurement front-ends over older TL074 equivalents. |
| Zener-trimmed offset voltage | Reduces initial VIO to ≤6 mV (C-suffix) and limits drift to 1 μV/°C, easing calibration in temperature-varying environments. |
| Wide supply range (±3.5 V to ±18 V) | Supports both low-voltage portable designs and industrial ±15 V legacy systems without redesign. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar FET-input operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL074CDR | Higher supply current (1.4 mA/ch), higher input noise (18 nV/√Hz), no guaranteed 100 Ω drive spec. | Lower precision, less suitable for ultra-low-power or high-fidelity sensor front-ends. | Select when cost sensitivity outweighs power/noise requirements and legacy PCB layout reuse is critical. |
| OPA4134UA | Lower VIO (500 μV max), lower noise (8 nV/√Hz), higher GBW (4 MHz), but 2.5 mA/ch supply current. | Better for audio and high-speed precision; not drop-in due to different pinout and quiescent current demands. | Choose for upgraded performance where board space and power budget allow re-layout and thermal redesign. |
Compared with TL074CDR, TLE2064CDRG4 reduces supply current by >90% and improves noise floor by 2×, while matching SOIC-14 footprint; versus OPA4134UA, it trades bandwidth and noise for microamp-level quiescent operation-making it optimal for always-on, multi-channel, low-power industrial sensing.

FAQ
What is the maximum operating temperature range for the TLE2064CDRG4?
The TLE2064CDRG4 is rated for 0°C to 70°C free-air operating temperature (C-suffix grade). This range is validated per TI's SLOS193D datasheet Section 5.2 and applies to all electrical characteristics including VIO, SR, and CMRR. Operation outside this range requires derating or selection of I-suffix (–40°C to 85°C) or M-suffix (–55°C to 125°C) variants. The TLE2064CDRG4 itself is not characterized for extended temperatures.
Does the TLE2064CDRG4 support rail-to-rail input or output operation?
The TLE2064CDRG4 does not provide rail-to-rail input or output operation. Its common-mode input range is –11 V to +13 V at ±15 V supply (i.e., within 2 V of each rail), and output swing is typically ±12.5 V into 600 Ω-leaving ~2.5 V headroom. Full rail-to-rail performance is not specified; designs requiring such capability should consider newer alternatives like the OPA4320. The TLE2064CDRG4 datasheet explicitly defines these limitations in Sections 5.2 and 5.5.
What is the input bias current specification for the TLE2064CDRG4 at 25°C?
The input bias current for the TLE2064CDRG4 is ±10 pA (typical) at 25°C, as stated in Section 5.3 of the SLOS193D datasheet under "IIB Input bias current" for TLE2061C (same core design). This ultra-low value stems from its JFET-input architecture and enables use with feedback resistors >1 MΩ without significant DC error. Maximum values are not specified, but full-range testing shows ≤2 nA at 70°C per Section 5.3.
Can the TLE2064CDRG4 drive a 100 Ω load effectively?
Yes-the TLE2064CDRG4 is explicitly specified for high-output-drive operation into 100 Ω loads per its "Features" section and Section 5.5 (VOM± tests at RL = 600 Ω and RL = 100 Ω). At ±15 V supply, it delivers ≥±12 V swing into 100 Ω (confirmed in Table 5-5, "VOM+" and "VOM–" rows). This makes the TLE2064CDRG4 suitable for driving coaxial cables, ADC input buffers, and low-impedance transducers without external gain boosting stages.
Is the TLE2064CDRG4 pin-compatible with the TL074 series?
No-the TLE2064CDRG4 and TL074 share the SOIC-14 package outline but differ in internal pin mapping. While both place VCC+ at pin 12 and VCC− at pin 4, the TLE2064CDRG4 assigns pin 14 to IN− D (per Figure 4-4), whereas TL074 places IN+ D at pin 14. This inversion breaks functional compatibility. Substituting TL074 for TLE2064CDRG4 requires PCB layout revision and signal routing changes to maintain correct amplifier polarity.
