Product details
Overview
TLE2027MDG4 from Texas Instruments is a military-grade, low-noise, high-speed precision operational amplifier in an 8-pin SOIC (D) 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 ±19 V supply capability - enabling high-fidelity signal conditioning in radar front-ends, precision test equipment, and avionics sensor interfaces.
For engineers reviewing the TLE2027MDG4 datasheet, TLE2027MDG4 pinout, TLE2027MDG4 application, or TLE2027MDG4 equivalent, key selection criteria include its −55°C to +125°C operating range, Excalibur process–enabled dc precision, saturation recovery circuitry, and compatibility with high-impedance transducer interfaces requiring sub-μV offset stability and ultra-low 1/f noise.
Technical Context
The TLE2027MDG4 employs a proprietary Excalibur bipolar process to achieve simultaneous high dc precision and wide ac bandwidth. Its internal architecture includes precision matched transistor pairs for offset minimization, on-chip offset nulling terminals (OFFSET N1/N2), and saturation recovery circuitry that reduces recovery time after overdrive.
It operates as a single-channel, internally compensated op amp optimized for unity-gain stability. Unlike the decompensated TLE2037 series, the TLE2027MDG4 supports stable operation at AV = 1 with 55° phase margin and 30 kHz maximum output-swing bandwidth into 2 kΩ.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | 25 μV max (−55°C to +125°C); enables <100 ppm error in 16-bit precision systems without trimming |
| Input Voltage Noise | 3.3 nV/√Hz @ 10 Hz; critical for low-frequency sensor amplification (e.g., strain gauges, thermopiles) |
| Unity-Gain Bandwidth | 13 MHz typ (−55°C to +125°C); supports stable closed-loop gain ≥1 with >55° phase margin |
| Supply Voltage Range | ±4 V to ±19 V; accommodates wide dynamic range in military power rails and dual-supply instrumentation |
| Common-Mode Input Range | −10.3 V to +10.3 V (full temp range); allows direct interfacing with ±10 V industrial analog I/O standards |
| Slew Rate | 1.0 V/μs min (−55°C to +125°C); sufficient for 10 Vpp signals up to ~160 kHz without distortion |

Pinout & Package
Package: 8-pin SOIC (D), surface-mount, tape-and-reel compatible (R suffix option). Pin 1 index marker located at top-left corner when viewed from top with marking side up.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OFFSET N1 | Null adjustment terminal - connects to potentiometer wiper for manual offset trimming |
| 2 | IN− | Inverting input - high-impedance node for feedback network connection |
| 3 | IN+ | Non-inverting input - accepts low-current sensor signals (e.g., bridge outputs) |
| 4 | VCC− | Negative supply rail - must be decoupled locally with ≥0.1 μF ceramic capacitor |
| 5 | OFFSET N2 | Null adjustment terminal - connects to potentiometer end for balanced offset correction |
| 6 | VCC+ | Positive supply rail - requires local decoupling; supports up to +19 V |
| 7 | OUT | Amplified output - drives loads down to 600 Ω with ±10 V swing (full temp range) |
| 8 | NC | No connect - internally unconnected; must remain floating per TI design rules |
Key Features
| Feature | Design Value |
|---|---|
| Excalibur Process Technology | Enables 25 μV max VIO and 3.3 nV/√Hz noise simultaneously - unattainable with standard bipolar processes |
| Offset Null Terminals (Pins 1 & 5) | Supports <5 μV residual offset after trimming - essential for DC-coupled precision measurement chains |
| Saturation Recovery Circuitry | Reduces overdrive recovery time to <1 μs - prevents settling errors in fast-pulse applications like LIDAR receivers |
| Military Temperature Range | Rated for −55°C to +125°C operation with full parameter guarantees - qualified per MIL-PRF-38535 |
| High Supply Rejection (105 dB) | Minimizes sensitivity to ripple on ±15 V rails - critical in shared-power avionics subsystems |

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 @ 1 kHz), but no offset null pins; 10 μV max VIO; −55°C to +125°C rated | Lacks manual offset trim capability - unsuitable where field calibration is required | Choose OPA277MD only if system-level auto-calibration replaces manual nulling and lower 1 kHz noise is prioritized |
| AD797ARMZ | Higher slew rate (20 V/μs), lower noise (0.9 nV/√Hz), but limited to −40°C to +85°C; no offset null pins | Not qualified for extended military temperature range; lacks saturation recovery circuitry | Select AD797ARMZ only for commercial high-speed applications where ambient temperature stays below 85°C |
Compared with OPA277MD and AD797ARMZ, the TLE2027MDG4 uniquely combines military temperature rating, user-accessible offset nulling, and integrated saturation recovery - making it irreplaceable in field-deployable analog signal chains requiring long-term zero-stability without firmware intervention.

FAQ
What is the guaranteed input offset voltage specification for TLE2027MDG4 over its full operating temperature range?
The TLE2027MDG4 has a maximum input offset voltage of 105 μV across its full −55°C to +125°C operating range, with a typical value of 20 μV at 25°C. This specification is production-tested and guaranteed per MIL-PRF-38535 requirements, ensuring predictable performance in mission-critical analog signal paths without reliance on post-manufacture screening.
Does TLE2027MDG4 require external compensation for unity-gain stability?
No, the TLE2027MDG4 is internally compensated and fully stable at unity gain, delivering 55° phase margin with 2 kΩ load and 100 pF capacitive load. Its compensation network is optimized for the Excalibur process, eliminating need for external capacitors - unlike the decompensated TLE2037 series which requires minimum AV = 5.
Can the offset null terminals (Pins 1 and 5) of TLE2027MDG4 be left unconnected in production designs?
No - leaving OFFSET N1 and OFFSET N2 unconnected may cause unpredictable offset drift or increased noise. TI specifies connecting them to a 10-kΩ potentiometer (wiper to Pin 1, ends to Pins 1 and 5) for active trimming, or shorting Pins 1 and 5 together if nulling is not required. Floating these pins violates recommended operating conditions.
What is the maximum continuous output current capability of TLE2027MDG4 at elevated temperatures?
The TLE2027MDG4 supports ±50 mA output current continuously across its full −55°C to +125°C range, as specified in Absolute Maximum Ratings. However, thermal derating applies: in SOIC (D) package at TA = 125°C, power dissipation is limited to 145 mW, restricting sustained output current to ~±12 mA into 600 Ω before junction temperature exceeds 150°C.
How does the saturation recovery circuitry in TLE2027MDG4 improve performance in pulse-amplification applications?
The saturation recovery circuitry in TLE2027MDG4 actively clamps internal nodes during overdrive, reducing recovery time from typical op amp values (>10 μs) to <1 μs. This ensures accurate pulse amplitude and timing fidelity in applications like pulsed LIDAR receivers or time-of-flight sensors - where conventional op amps introduce measurable settling errors after large transient events.
