Product details
Overview
TLE2027AMD from Texas Instruments is a military-grade Excalibur low-noise, high-speed precision operational amplifier in an 8-pin ceramic DIP (JG) package. It delivers 25 μV max input offset voltage at −55°C to +125°C, 3.3 nV/√Hz input voltage noise at 10 Hz, 15 MHz unity-gain bandwidth, and rail-to-rail output swing capability up to ±13.5 V with 2 kΩ load - enabling high-fidelity signal conditioning in aerospace sensor interfaces and precision test equipment.
For engineers reviewing the TLE2027AMD datasheet, TLE2027AMD pinout, TLE2027AMD application, or TLE2027AMD equivalent, key selection criteria include its guaranteed 25 μV VIO over full military temperature range, saturation recovery circuitry for fast overload recovery, and compatibility with ±4 V to ±19 V dual supplies - critical for ruggedized analog front-ends requiring long-term dc stability and low 1/f noise.
Technical Context
The TLE2027AMD uses TI's Excalibur bipolar process to achieve simultaneous high dc precision and wide ac bandwidth. Its internal architecture includes offset-nulling circuitry with two dedicated trim pins (OFFSET N1/N2), a high-slew-rate output stage with saturation recovery, and optimized compensation for unity-gain stability without external components.
It operates across ±4 V to ±19 V supplies with common-mode input range extending to ±10.3 V at full temperature range, and maintains 131 dB typical CMRR and 144 dB typical PSRR - making it suitable for high-gain, low-drift instrumentation where supply and common-mode variations must not corrupt signal integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage (VIO) | 25 μV max over −55°C to +125°C - ensures minimal dc error in precision gain stages without manual trimming. |
| Unity-Gain Bandwidth | 13 MHz typ - supports stable closed-loop operation up to 10× gain with >55° phase margin. |
| Input Voltage Noise (Vn) | 3.3 nV/√Hz at 10 Hz, 2.5 nV/√Hz at 1 kHz - enables low-noise amplification of microvolt-level sensor signals. |
| Large-Signal Differential Gain (AVD) | 45 V/μV typ at RL = 2 kΩ - provides >132 dB open-loop gain for sub-μV resolution in feedback networks. |
| Supply Voltage Range | ±4 V to ±19 V - accommodates legacy ±15 V systems and extended-range industrial supplies. |
| Output Voltage Swing | ±13.5 V into 2 kΩ at ±15 V supply - delivers near-rail performance for maximum dynamic range in single-supply-derived bipolar rails. |
| Common-Mode Input Range | −10.3 V to +10.3 V at full temperature - allows direct interfacing with ±10 V DACs or transducer outputs. |
Pinout & Package
Package: 8-pin ceramic dual in-line package (JG), hermetically sealed, rated for −55°C to +125°C operation, lead finish compatible with 300°C soldering per MIL-STD-202.

| 5 (OFFSET N2) | Offset null adjustment terminal | Connects to potentiometer end for VIO trimming circuit; used with Pin 1 to balance input stage mismatch. |
| 6 (OUT) | Amplifier output | Capable of ±50 mA continuous output; features saturation recovery for <1 μs recovery from overload. |
| 7 (VCC+) | Positive supply rail | Accepts +4 V to +19 V; total current in ≤ 50 mA; decoupling recommended within 1 cm. |

Key Features
| Feature | Design Value |
|---|---|
| Excalibur process technology | Enables 25 μV max VIO and 3.3 nV/√Hz 1/f noise simultaneously - unattainable in standard bipolar op-amps. |
| Saturation recovery circuitry | Reduces overload recovery time to <1 μs - prevents signal distortion during transient overdrive in data acquisition systems. |
| Dual offset null terminals (Pins 1 & 5) | Supports active trimming to <5 μV residual offset - essential for 18-bit+ precision measurement front-ends. |
| MIL-PRF-38535 compliant screening | Qualified for Class B or S levels per manufacturer documentation - meets requirements for flight-critical avionics and defense electronics. |
| Stable at unity gain | No external compensation required - simplifies design of low-gain buffers, active filters, and I/V converters. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA277MD | Lower noise (2.8 nV/√Hz), wider supply range (±22 V), but only 10 MHz GBW and no offset null pins. | Lacks manual trimming capability; unsuitable where VIO drift must be actively canceled over temperature. | Select when ultra-low noise dominates over trimmability and bandwidth is secondary. |
| AD797ARZ | Superior 1.1 nV/√Hz noise and 110 MHz GBW, but 200 μV VIO max and no military temp rating. | Not qualified for −55°C to +125°C operation; requires external offset compensation for precision dc gain. | Select for high-frequency, low-noise AC-coupled applications where dc precision is relaxed. |
Compared with OPA277MD and AD797ARZ, the TLE2027AMD uniquely combines military-temperature-rated 25 μV VIO, dual offset null pins, and 13 MHz bandwidth - making it the only choice for space-qualified analog front-ends demanding both long-term dc stability and fast transient response.

FAQ
What is the maximum operating temperature range for the TLE2027AMD?
The TLE2027AMD is specified for continuous operation from −55°C to +125°C ambient temperature, meeting MIL-PRF-38535 Class B or S screening requirements. This full military temperature range is confirmed in the "TLE20x7M electrical characteristics" section of the SLOS192C datasheet, where all parameters - including 25 μV max VIO and 13 MHz unity-gain bandwidth - are guaranteed across this interval.
Does the TLE2027AMD require external compensation for unity-gain stability?
No, the TLE2027AMD is internally compensated for unity-gain stability, as verified by its 55° phase margin at unity gain (Figure 3, SLOS192C). Unlike the decompensated TLE2037 series, the TLE2027AMD does not require minimum closed-loop gain and can be used directly as a voltage follower or in low-gain configurations without risk of oscillation.
How is the offset voltage trimmed on the TLE2027AMD?
The TLE2027AMD provides two dedicated offset null terminals: Pin 1 (OFFSET N1) and Pin 5 (OFFSET N2). A 20 kΩ potentiometer is connected between these pins with its wiper grounded; adjusting the potentiometer balances the input stage, reducing VIO to <5 μV. This method is explicitly documented in the "Pin Assignments" diagram and "Offset Nulling" application note in the SLOS192C datasheet.
What is the purpose of Pin 8 (NC) on the TLE2027AMD?
Pin 8 on the TLE2027AMD is a true no-connect terminal - it is not bonded internally and carries no electrical function. The datasheet's "D, JG, OR P PACKAGE (TOP VIEW)" diagram confirms Pin 8 as NC, and the absolute maximum ratings table specifies no current or voltage limits for this pin. It must remain unconnected and floating in PCB layout to avoid unintended coupling or mechanical stress.
Can the TLE2027AMD drive capacitive loads without instability?
The TLE2027AMD is characterized with 100 pF capacitive load in all AC performance tests (e.g., slew rate, unity-gain bandwidth), and remains stable under those conditions. However, for loads exceeding 100 pF, external isolation resistance (≥100 Ω) is recommended between the output and capacitance to maintain phase margin. This guidance is provided in TI's "Op Amp Stability Analysis" application report SLOA020B, which references the TLE2027 family's compensation design.
