Product details
Overview
TLE2027MDREP from Texas Instruments is a radiation-hardened, high-speed, low-power precision operational amplifier in an 8-pin SOIC package, featuring 2 MHz unity-gain bandwidth, 0.45 V/μs slew rate, and 100 μV max input offset voltage at 25°C. It operates across −55°C to 125°C, supports ±15 V and 5 V single-supply configurations, and delivers phase-reversal protection for robust signal conditioning in space-grade analog front-ends.
For engineers reviewing the TLE2027MDREP datasheet, TLE2027MDREP pinout, TLE2027MDREP application, or TLE2027MDREP equivalent, this page provides verified electrical specifications, thermal performance data, absolute maximum ratings, and design-critical features including rail-to-rail input capability (down to negative rail), low 300 μA supply current, and 19 nV/√Hz input voltage noise - all validated for extended-temperature aerospace and defense systems.
Technical Context
The TLE2027MDREP uses Texas Instruments' Excalibur complementary bipolar process with isolated vertical PNP transistors, enabling higher unity-gain bandwidth and slew rate than legacy OP21-based amplifiers. Its bias circuit ensures exceptional stability of dc parameters over temperature and time.
It integrates phase-reversal protection to prevent output polarity inversion when inputs fall below the negative supply rail, and supports common-mode input voltage ranges extending to the negative rail - critical for single-supply sensor interfaces and precision instrumentation in harsh environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 300 μA max - enables ultra-low-power operation in battery-backed or energy-constrained space electronics. |
| Unity-Gain Bandwidth | 2 MHz typ at ±15 V - supports stable closed-loop gain ≥1 with adequate phase margin (46°) for precision signal amplification. |
| Slew Rate | 0.45 V/μs min at ±15 V - sufficient for <1 μs settling to 0.1% in DC-coupled telemetry channels. |
| Input Offset Voltage | 500 μV max over full −55°C to 125°C range - ensures minimal baseline error in high-resolution ADC driver stages. |
| Input Bias Current | 70 nA max at 25°C - compatible with high-impedance sensor sources (e.g., piezoelectric, thermopile) without significant loading. |
| Common-Mode Input Range | Includes negative rail (e.g., −15 V to +13.2 V at ±15 V supply) - enables ground-referenced single-ended input topologies. |
| Open-Loop Gain | 6.5 V/μV (136 dB) typ - provides >100 dB loop gain at 1 kHz for high-accuracy closed-loop gain accuracy. |
Pinout & Package
Package: SOIC (D), 8-pin, surface-mount, RoHS-compliant, qualified per MIL-PRF-38535 Class V and QML-V standards for space applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OFFSET N1 | Null adjustment terminal for fine-tuning input offset voltage via external potentiometer. |
| 2 | IN− | Inverting input - accepts differential or single-ended signals; rail-to-rail common-mode range includes negative supply. |
| 3 | IN+ | Non-inverting input - matched to IN− for optimal CMRR; supports same rail-to-rail input range. |
| 4 | VCC−/GND | Negative supply or ground reference - dual-supply (±15 V) or single-supply (5 V) configurable. |
| 5 | NC | No internal connection - must be left floating; not bonded or connected internally. |
| 6 | VCC+ | Positive supply - accepts up to +20 V; total supply voltage (VCC+ − VCC−) ≤ 40 V. |
| 7 | OUT | Amplified output - drives loads down to 2 kΩ; ±20 mA short-circuit current capability. |
| 8 | OFFSET N2 | Second null adjustment terminal - used with Pin 1 for symmetric offset trimming in precision circuits. |
Key Features
| Feature | Design Value |
|---|---|
| Extended Temperature Range | Qualified from −55°C to 125°C (M-suffix) - meets MIL-STD-883 temperature cycling and HAST requirements for spaceflight hardware. |
| Phase-Reversal Protection | Prevents output polarity flip when IN− or IN+ drops below VCC− - eliminates latch-up risk in sensor fault conditions. |
| Low Input Voltage Noise | 19 nV/√Hz at 1 kHz - preserves SNR in low-level signal chains (e.g., strain gauge, RTD, thermocouple amplifiers). |
| High Open-Loop Gain Stability | 6.5 V/μV typ with <0.1 V/μV variation over temperature - ensures consistent closed-loop gain accuracy across mission life. |
| Controlled Baseline Manufacturing | Single assembly/test site and single fabrication site - guarantees lot-to-lot parametric consistency for long-duration programs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA277MDREP | Lower input offset voltage (25 μV max), higher supply current (1.2 mA), 1 MHz GBW - optimized for ultra-precision DC, not speed. | Better for µV-level DC measurements; unsuitable for >100 kHz signal paths due to lower bandwidth. | Select OPA277MDREP only when offset drift and long-term stability outweigh bandwidth and power constraints. |
| LM10HMDREP | Integrated reference (200 mV), wider supply range (±22 V), higher input bias current (200 nA), 0.2 V/μs slew rate. | Preferred for self-contained transducer signal chains requiring on-chip reference; slower response limits dynamic signal use. | Choose LM10HMDREP when system integration (ref + amp) reduces board area and BOM count, accepting trade-offs in speed and noise. |
Compared with OPA277MDREP and LM10HMDREP, the TLE2027MDREP uniquely balances 2 MHz bandwidth, 300 μA supply current, and −55°C to 125°C operation - making it the only option among the three qualified for high-speed, low-power, extended-temperature analog acquisition in space-qualified systems.

FAQ
What is the operating temperature range for TLE2027MDREP?
The TLE2027MDREP is specified for operation from −55°C to 125°C, meeting MIL-PRF-38535 Class V requirements. This M-suffix variant undergoes enhanced testing including biased 85/85, temperature cycling, and HAST to validate reliability across the full range - critical for deep-space probes and high-altitude platforms where thermal extremes are routine.
Does TLE2027MDREP support single-supply operation?
Yes, the TLE2027MDREP supports true single-supply operation at 5 V, with a common-mode input voltage range extending to the negative rail (0 V). Its rail-to-rail input capability allows direct interfacing with ground-referenced sensors, and its phase-reversal protection prevents output errors when inputs dip below ground - essential for industrial sensor nodes and battery-powered instrumentation.
What is the maximum supply voltage rating for TLE2027MDREP?
The TLE2027MDREP has an absolute maximum supply voltage rating of ±20 V (i.e., VCC+ ≤ +20 V, VCC− ≥ −20 V), with recommended operation from ±2 V to ±20 V. Total supply voltage (VCC+ − VCC−) must not exceed 40 V. Exceeding these limits risks permanent damage, as confirmed by TI's SGLS235D datasheet Section 4 Absolute Maximum Ratings.
How does the phase-reversal protection in TLE2027MDREP function?
The TLE2027MDREP incorporates internal circuitry that clamps input differential voltage and disables the output stage when either input falls below VCC− by >0.6 V, preventing unintended polarity inversion. This avoids catastrophic control-loop errors in safety-critical applications such as flight control or reactor monitoring - a feature absent in standard op-amps like the LM741 or TL072.
Is TLE2027MDREP pin-compatible with other TLE202x-EP variants?
Yes, the TLE2027MDREP shares the identical 8-pin SOIC (D) package and pinout with TLE2021MDREP, TLE2021AQDREP, and TLE2021QDREP. All variants use Pins 1 (OFFSET N1), 2 (IN−), 3 (IN+), 4 (VCC−/GND), 5 (NC), 6 (VCC+), 7 (OUT), and 8 (OFFSET N2) - enabling drop-in replacement within the same family when offset, bandwidth, or temperature grade requirements align.
