Product details
Overview
TLE2027MD 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, 3.3 nV/√Hz input voltage noise at 10 Hz, 15 MHz unity-gain bandwidth, and operates across −55°C to +125°C. It serves as a drop-in upgrade for legacy precision op-amps in analog front-ends of aerospace instrumentation and radiation-tolerant signal conditioning circuits.
For engineers reviewing the TLE2027MD datasheet, TLE2027MD pinout, TLE2027MD application, or TLE2027MD 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 high-reliability analog measurement systems requiring long-term dc stability and low 1/f noise.
Technical Context
The TLE2027MD uses TI's Excalibur bipolar process to achieve simultaneous high dc precision and wide ac bandwidth. Its internal architecture includes laser-trimmed thin-film resistors for offset calibration, a composite input stage minimizing 1/f noise, and dedicated saturation recovery circuitry that reduces output recovery time after overdrive.
Unlike the decompensated TLE2037 series, the TLE2027MD is unity-gain stable with 55° phase margin and supports closed-loop gains ≥1. It features rail-to-rail input common-mode range (±10.3 V at full temperature range) and delivers ±11 V output swing into 2 kΩ load at ±15 V supply.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage (VIO) | 25 μV max over −55°C to +125°C - enables sub-100 ppm dc accuracy without external trimming in precision sensor interfaces. |
| Unity-Gain Bandwidth | 13 MHz typical - supports stable amplification of signals up to ~8 MHz with ≤1% gain error in unity-gain buffer configurations. |
| Input Voltage Noise (Vn) | 3.3 nV/√Hz at 10 Hz, 2.5 nV/√Hz at 1 kHz - ensures minimal contribution to total system noise in low-frequency precision measurements. |
| Large-Signal Differential Gain (AVD) | 45 V/μV typical at RL = 2 kΩ - provides >133 dB open-loop gain for high-accuracy closed-loop gain setting with <0.001% linearity error. |
| Supply Voltage Range | ±4 V to ±19 V - accommodates wide industrial and military power rails while maintaining specified performance. |
| Common-Mode Input Range | −10.3 V to +10.3 V at full temperature - allows direct interfacing with ±10 V sensor outputs without level-shifting circuitry. |

Key Features
| Feature | Design Value |
|---|---|
| Excalibur Process Bipolar Technology | Enables simultaneous 25 μV VIO max and 15 MHz GBW - unattainable in standard bipolar op-amps of same era. |
| Saturation Recovery Circuitry | Reduces output recovery time after overdrive by >5× vs conventional precision op-amps, critical for pulse-amplifier front-ends. |
| Military Temperature Range (−55°C to +125°C) | Guaranteed parametric performance across full range - eliminates derating uncertainty in avionics and space-qualified designs. |

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 input voltage noise (2.8 nV/√Hz @ 1 kHz), but only 10 MHz GBW and 10 μV VIO max; not MIL-qualified. | Preferred for ultra-low-noise audio or medical EEG front-ends where military temp range is unnecessary. | Select OPA277MD when 10 μV VIO and lower broadband noise outweigh need for −55°C operation and saturation recovery. |
| LM108AJ | Older design with 75 μV VIO max, 1.5 MHz GBW, no saturation recovery; JG package but non-laser-trimmed. | Suitable for cost-sensitive legacy upgrades where 25 μV VIO and 15 MHz bandwidth are not required. | Choose LM108AJ only for backward-compatible replacements in existing JG-footprint designs with relaxed precision specs. |
Compared with OPA277MD and LM108AJ, the TLE2027MD uniquely combines military temperature qualification, laser-trimmed 25 μV VIO, and integrated saturation recovery - making it the sole option for new high-reliability designs demanding both precision and robustness under thermal stress.

FAQ
What is the maximum operating temperature range for the TLE2027MD?
The TLE2027MD is rated for continuous operation from −55°C to +125°C, fully compliant with MIL-PRF-38535 requirements. This extended range is validated across all electrical parameters including input offset voltage (25 μV max), common-mode input range (±10.3 V), and supply current (3.8–5.3 mA). The ceramic JG package ensures mechanical and thermal stability under thermal shock conditions encountered in aerospace deployments. TLE2027MD maintains full specification compliance across this entire range without derating.
Does the TLE2027MD require external offset nulling in precision applications?
The TLE2027MD incorporates laser-trimmed thin-film resistors that guarantee ≤25 μV input offset voltage over −55°C to +125°C, eliminating the need for external nulling in most applications. Pins 1 and 5 (OFFSET N1/N2) are provided for optional fine calibration using a 10-kΩ potentiometer, but this is only necessary when sub-5 μV residual offset is required. For typical high-precision sensor interfaces, TLE2027MD achieves required accuracy without any external components. TLE2027MD's low temperature coefficient (0.4 μV/°C) further minimizes drift-induced recalibration needs.
Can the TLE2027MD drive capacitive loads without instability?
The TLE2027MD is unity-gain stable with a minimum phase margin of 55° into 2 kΩ || 100 pF (including fixture capacitance), per Figure 3 test conditions. It can safely drive ≤100 pF directly; for larger capacitive loads (e.g., ADC input capacitance >100 pF), a small isolation resistor (20–50 Ω) between TLE2027MD output and load is recommended. Unlike decompensated variants (TLE2037), the TLE2027MD does not require minimum closed-loop gain for stability. TLE2027MD's internal compensation ensures predictable step response and absence of ringing in standard gain configurations.
How does the saturation recovery circuitry in the TLE2027MD improve system performance?
The TLE2027MD integrates dedicated saturation recovery circuitry that actively clamps internal nodes during overdrive, reducing output recovery time by >5× compared to standard precision op-amps. In pulse-amplifier applications - such as radar receiver front-ends or time-of-flight sensor conditioning - this prevents dead-time errors and preserves timing accuracy after large transient events. Measured recovery from ±13 V overdrive to 0.1% final value takes <1.5 μs. This feature is intrinsic to the TLE2027MD silicon design and requires no external components. TLE2027MD's recovery behavior is fully characterized across −55°C to +125°C.
Is the TLE2027MD pin-compatible with other op-amps in the same JG package footprint?
Yes, the TLE2027MD uses the industry-standard 8-pin ceramic DIP (JG) pinout defined in TI's SLOS192C datasheet: pin 1 = OFFSET N1, pin 2 = IN−, pin 3 = IN+, pin 4 = VCC−, pin 5 = OFFSET N2, pin 6 = OUT, pin 7 = VCC+, pin 8 = NC. This matches legacy devices like LM108AJ and modern alternatives such as OPA277MD (JG variant), enabling direct PCB replacement without layout modification. However, functional equivalence (e.g., gain stability, noise, offset) must be verified per application. TLE2027MD retains identical mechanical dimensions and soldering profiles as standard JG packages.
