Product details
Overview
TLE2064AMDR from Texas Instruments is a quad FET-input operational amplifier with 36V supply capability, 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 aerospace flight control units and industrial analog input modules.
For engineers reviewing the TLE2064AMDR datasheet, TLE2064AMDR pinout, TLE2064AMDR application, or TLE2064AMDR equivalent, this page delivers verified specifications, package mapping to SOIC-14, functional context for high-voltage, low-noise analog front-ends, and validated alternative options for extended-temperature designs.
Technical Context
The TLE2064AMDR uses JFET-input transistors with on-chip Zener trimming for DC precision, enabling stable offset voltage (≤4mV at 25°C) across –55°C to 125°C operation. Its architecture supports rail-to-rail output swing into 10kΩ and maintains ≥1.1MHz bandwidth even under ±15V supplies.
It delivers 2.2–2.6 V/µs slew rate, 43–40 nV/√Hz input voltage noise at 1kHz, and 46°–58° phase margin-enabling stable unity-gain configurations with capacitive loads up to 100pF. Common-mode rejection exceeds 72dB and supply rejection reaches 93dB at ±15V.
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 (e.g., AV = 10). |
| Supply Current per Channel | 120 μA (typical) - Supports battery-powered or energy-constrained systems without sacrificing AC performance. |
| Input Offset Voltage (max) | 4 mV at 25°C - Meets precision requirements for sensor amplification and analog I/O where calibration headroom is limited. |
| Output Drive Capability | Specified into 100Ω - Allows direct driving of low-impedance loads such as transmission lines or ADC input buffers without external buffering. |
| Operating Temperature Range | –55°C to +125°C - Qualified for military, avionics, and downhole industrial environments requiring extreme thermal resilience. |
| Common-Mode Rejection Ratio | 72 dB (min) - Rejects noise coupled onto differential sensor inputs in noisy motor-control or engine-monitoring systems. |
| Supply-Voltage Rejection Ratio | 93 dB (min at ±15V) - Maintains accuracy despite ripple or variation in split-supply rails common in legacy analog subsystems. |
Pinout & Package
Package: SOIC-14 (D), 8.65 mm × 6 mm, surface-mount, tape-and-reel compatible (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 | Output | Amplified output of each of four independent op-amp sections. |
| 2, 6, 10, 14 | Inverting Input (–) | Differential input node for negative feedback configuration; high impedance (>1 TΩ). |
| 3, 7, 11, 12 | Non-Inverting Input (+) | Differential input node for positive signal reference; matched bias current minimizes offset error. |
| 4 | VCC– | Negative supply rail connection for all four amplifiers; must be decoupled locally. |
| 8 | VCC+ | Positive supply rail connection for all four amplifiers; shared rail simplifies PCB layout. |
Key Features
| Feature | Design Value |
|---|---|
| FET-input architecture | Input bias current ≤3 pA (typical) enables high-impedance sensor interfacing (e.g., piezoelectric, pH electrodes) without loading error. |
| On-chip Zener-trimmed offset | Ensures ≤4 mV input offset over full temperature range, reducing need for external nulling circuitry in precision systems. |
| High-output-drive capability | Delivers ±12.5 V swing into 600Ω at ±15V supply-supports direct interface to legacy 12-bit SAR ADCs with 100Ω input impedance. |
| Low 1/f noise corner | 1.1 µVPP integrated noise (0.1–10 Hz) improves resolution in slow-sampling applications like thermocouple amplification. |
| Extended temperature qualification | Rated for –55°C to +125°C operation per MIL-PRF-38535, supporting deployment in unheated avionics bays and turbine enclosures. |

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 |
|---|---|---|---|
| OPA4134UA | Lower input noise (8 nV/√Hz), higher supply current (4mA/ch), no extended-temp grade | Optimized for audio-grade fidelity, not qualified for –55°C operation | Select when ultra-low noise dominates over power and temperature range. |
| LMC6084IMX | CMOS input (fA-level bias), lower GBW (1.3 MHz), wider VCC range (±16V), no M-grade temp option | Targeted at medical instrumentation and portable test equipment with single-supply flexibility | Select when femtoampere input leakage is mandatory and extended temperature is not required. |
Compared with OPA4134UA and LMC6084IMX, the TLE2064AMDR uniquely balances ultra-low power (120μA/ch), military-grade temperature range (–55°C to +125°C), and robust 100Ω drive capability-making it irreplaceable in weight- and power-constrained avionics signal chains where reliability trumps raw noise performance.

FAQ
What is the maximum supply voltage rating for the TLE2064AMDR?
The TLE2064AMDR has an absolute maximum supply voltage rating of ±18 V (36 V total), with recommended operating range of ±3.5 V to ±18 V. This enables compatibility with legacy ±15 V industrial and avionics power rails while maintaining safe margin against transients.
Does the TLE2064AMDR support operation at –55°C?
Yes, the TLE2064AMDR is fully specified and tested over –55°C to +125°C, meeting MIL-PRF-38535 Class K requirements. All key parameters-including input offset voltage, CMRR, and slew rate-are guaranteed across this full range, making it suitable for unheated aircraft bays and turbine-mounted control electronics.
What is the typical input bias current of the TLE2064AMDR?
The typical input bias current of the TLE2064AMDR is 3 pA at 25°C, with a maximum of 30 nA over the full –55°C to +125°C range. This ultra-low bias current stems from its JFET-input architecture and enables accurate amplification of high-impedance sources like piezoelectric sensors and photodiode transimpedance nodes without significant DC error.
Can the TLE2064AMDR drive a 100Ω load effectively?
Yes-the TLE2064AMDR is explicitly characterized into 100Ω loads per the datasheet, delivering ±12.5 V output swing at ±15 V supply. Its high-output-drive design avoids clipping or distortion when interfacing directly to low-impedance ADC inputs, transmission lines, or active filters without external buffer stages.
Is the TLE2064AMDR pin-compatible with other quad op-amps in SOIC-14 packages?
No-while the TLE2064AMDR uses the industry-standard SOIC-14 footprint, its pinout (dual VCC rails shared across all four amplifiers, with outputs on pins 1/5/9/13) differs from conventional "single-supply" or "split-rail-per-section" quad op-amps. Direct replacement requires verification of pin function alignment and power topology compatibility.
