Product details
Overview
TLE2062AMD from Texas Instruments is a dual, JFET-input operational amplifier with high-output-drive capability, 1.1 MHz gain-bandwidth product, ±3.5 V to ±18 V supply range, and 120 µA per channel typical supply current. It delivers rail-to-rail output swing into 100 Ω loads and operates across –55°C to +125°C for aerospace and industrial control signal conditioning.
For engineers reviewing the TLE2062AMD datasheet, TLE2062AMD pinout, TLE2062AMD application, or TLE2062AMD equivalent, this device is selected for precision analog front-ends in harsh-environment systems where low power, high voltage tolerance, and FET-input bias stability are critical - especially in flight control units and engine management interfaces.
Technical Context
The TLE2062AMD uses on-chip Zener trimming for offset voltage calibration and JFET-input transistors to achieve femtoampere-level input bias current (≤30 nA max over full temperature range) and high common-mode rejection (≥65 dB). Its architecture supports stable unity-gain operation with ≥58° phase margin at 10 kΩ load and 100 pF capacitance.
It is specified for high-output-drive performance into low-impedance loads (e.g., 100 Ω), enabling direct interface with cables, ADC drivers, or actuator circuits without external buffers - a key differentiator versus standard micropower op-amps.
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) in sensor signal chains. |
| Supply Current per Channel | 120 µA (typical) - allows battery-powered or energy-constrained systems to integrate dual-channel precision amplification with minimal quiescent load. |
| Input Offset Voltage (max) | 4 mV at 25°C - supports DC-coupled applications like analog input modules where sub-mV error is not required but drift stability matters. |
| Output Drive Capability | Specified into 100 Ω - permits direct driving of transmission lines, low-Z transducers, or multiplexed ADC inputs without buffer stages. |
| Operating Temperature Range | –55°C to +125°C - qualified for military, avionics, and under-hood automotive environments per M-grade specifications. |
| Common-Mode Input Range | –11 V to +13 V at ±15 V supplies - accommodates wide-swing sensor outputs (e.g., strain gauge bridges) without level-shifting. |
| Slew Rate | 2.6 V/µs (typical at ±15 V) - sufficient for <10 kHz full-scale step response in control loop feedback paths. |
Pinout & Package
Ceramic Dual-In-Line Package (CDIP-8), 9.6 mm × 6.67 mm, hermetically sealed for high-reliability operation in extended temperature and radiation-prone environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NC | No connection - unused terminal; must be left floating or grounded per layout guidelines. |
| 2 | VCC– | Negative supply rail - connects to system ground or negative voltage; decoupling capacitor required within 1 cm. |
| 3 | IN+ | Non-inverting input - high-impedance (≥1 TΩ) FET node; sensitive to leakage; guard ring recommended. |
| 4 | IN– | Inverting input - matched to IN+ for common-mode rejection; routing symmetry critical for precision. |
| 5 | OUT A | Amplifier A output - capable of sourcing/sinking >20 mA into 100 Ω while maintaining linearity. |
| 6 | NC | No connection - unused terminal; no internal bond wire; electrically isolated. |
| 7 | VCC+ | Positive supply rail - accepts up to +18 V; requires local 0.1 µF ceramic bypass capacitor. |
| 8 | OUT B | Amplifier B output - independent channel with identical drive and AC specs as OUT A. |
Key Features
| Feature | Design Value |
|---|---|
| FET-input architecture | Input bias current ≤30 nA over –55°C to +125°C - eliminates resistor-induced offset errors in high-impedance sensor interfaces. |
| Zener-trimmed offset voltage | Max 4 mV at 25°C (TLE2062AM grade) - reduces calibration burden in analog input modules and flight control signal conditioning. |
| High-output-drive capability | Specified into 100 Ω loads - enables direct interface with data acquisition systems and low-Z actuators without external buffers. |
| Extended temperature operation | –55°C to +125°C operating range - meets MIL-PRF-38535 Class B requirements for aerospace and defense platforms. |
| Low-noise FET input | 43 nV/√Hz input voltage noise at 1 kHz - suitable for amplifying low-level signals from piezoelectric or thermopile sensors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual FET-input op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA211IDR | Lower noise (1.1 nV/√Hz), higher GBW (45 MHz), but only rated to +125°C and consumes 3.6 mA/ch. | Not suitable for –55°C operation or ultra-low-power designs; better for high-speed precision, not micropower robustness. | Select when bandwidth and noise dominate; avoid if supply current <200 µA or temp <–40°C is required. |
| LMC6082IMX/NOPB | CMOS input (fA bias), rail-to-rail output, but GBW = 1.4 MHz and max supply = ±8 V; not rated below –40°C. | Lacks high-voltage operation and extended temperature support; suited for commercial instrumentation, not avionics. | Choose for ultra-low bias current in benign environments; reject for aerospace or high-supply applications. |
Compared with OPA211IDR and LMC6082IMX/NOPB, the TLE2062AMD uniquely balances micropower consumption (120 µA/ch), high-voltage tolerance (±18 V), and full military-grade temperature range (–55°C to +125°C) - making it irreplaceable in legacy and new-design flight control and engine management systems where reliability trumps speed.

FAQ
What is the maximum supply voltage rating for the TLE2062AMD?
The TLE2062AMD has an absolute maximum supply voltage rating of ±18 V (36 V total), with recommended operating range from ±3.5 V to ±18 V. Operation beyond ±18 V risks permanent damage. This rating enables use in high-voltage sensor excitation and industrial control rails where standard 5 V or 3.3 V op-amps fail.
Does the TLE2062AMD support rail-to-rail output swing?
The TLE2062AMD does not provide true rail-to-rail output swing. At ±15 V supplies and 10 kΩ load, its output swings to ±13 V (–13 V to +13 V); into 100 Ω, it delivers ±12 V. The specification emphasizes high drive into low impedances rather than output voltage headroom - a deliberate trade-off for robustness in demanding loads.
What is the input bias current specification for the TLE2062AMD over temperature?
The TLE2062AMD specifies input bias current ≤30 nA over its full operating range of –55°C to +125°C. At 25°C, typical IIB is 3 pA. This ultra-low, temperature-stable bias current is enabled by its JFET-input stage and makes the TLE2062AMD ideal for high-impedance source interfacing without significant DC error accumulation.
Is the TLE2062AMD pin-compatible with other TLE2062 variants?
Yes - the TLE2062AMD shares identical CDIP-8 pinout with all TLE2062xM variants (e.g., TLE2062M, TLE2062BM). Pin functions, spacing, and mechanical footprint are fully consistent across the M-grade family, enabling drop-in replacement within the same package type. However, it is not pin-compatible with SOIC or PDIP versions due to differing pin 1 orientation and body dimensions.
How does the TLE2062AMD's noise performance compare to earlier BiFET op-amps?
The TLE2062AMD exhibits a lower noise floor than earlier generations of low-power BiFET op-amps, with 43 nV/√Hz input voltage noise at 1 kHz and 1.1 µVPP integrated noise (0.1 Hz to 10 Hz). This improvement stems from optimized JFET geometry and trimming, directly benefiting precision DC and low-frequency AC measurements in engine control and flight systems.
