Product details
Overview
TLE2037MD from Texas Instruments is a decompensated, high-speed, low-noise precision operational amplifier optimized for closed-loop gains ≥5. It delivers 50 MHz gain-bandwidth product, 7.5 V/μs slew rate, 2.5 nV/√Hz input voltage noise at 1 kHz, 25 μV max input offset voltage, and operates across −55°C to +125°C. It serves in precision instrumentation front-ends, active filtering, and high-fidelity signal conditioning where bandwidth and dc accuracy must coexist.
For engineers reviewing the TLE2037MD datasheet, TLE2037MD pinout, TLE2037MD application, or TLE2037MD equivalent, key selection criteria include its decompensated stability requirement (AV ≥ 5), military-grade temperature range, Excalibur-process low-noise performance, and compatibility with ±4 V to ±19 V dual supplies in space-constrained D-package layouts.
Technical Context
The TLE2037MD uses Texas Instruments' Excalibur bipolar process to achieve simultaneous high dc precision and wide ac bandwidth. Its decompensated internal architecture enables 50 MHz GBW and 7.5 V/μs slew rate but mandates minimum closed-loop gain of 5 for stability - unlike the unity-gain-stable TLE2027MD.
It features saturation recovery circuitry for fast overdrive recovery, rail-to-rail output swing capability (±13.5 V into 2 kΩ), and robust common-mode rejection (131 dB typ) and supply rejection (144 dB typ), making it suitable for noisy industrial environments requiring stable gain and minimal drift over extreme temperature excursions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 50 MHz - Enables stable amplification up to 10 MHz at gain = 5, critical for wideband sensor signal conditioning. |
| Slew Rate | 7.5 V/μs - Supports clean 10 Vpp signals up to ~1.2 MHz without slew-induced distortion. |
| Input Voltage Noise | 2.5 nV/√Hz at 1 kHz - Low enough for µV-level thermocouple or strain gauge amplification without dominating system noise floor. |
| Input Offset Voltage | 25 μV max - Ensures ≤0.00025% gain error in 10 V full-scale precision measurement systems. |
| Operating Temperature Range | −55°C to +125°C - Qualified for aerospace, downhole, and military embedded control applications with no derating required. |
| Supply Voltage Range | ±4 V to ±19 V - Allows direct interface with legacy ±15 V analog rails and tolerance for transient overvoltage conditions. |
| Common-Mode Rejection | 131 dB typical - Rejects >2 million:1 of power-supply or ground-bounce interference in single-ended sensor interfaces. |
Pinout & Package
Package: 8-pin plastic small-outline (SOIC) D package, surface-mount, tape-and-reel compatible. Pin 1 marked by beveled corner or dot; standard industry pinout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OFFSET N1 | Null adjustment terminal - connects to external potentiometer for manual offset trimming; left unconnected if unused. |
| 2 | IN− | Inverting input - high-impedance node accepting feedback network; differential input voltage limited to ±1.2 V. |
| 3 | IN+ | Non-inverting input - high-impedance node for reference or signal source; common-mode range extends to ±10.3 V at full temp. |
| 4 | VCC− | Negative supply rail - must be connected to system ground or negative voltage; supports up to −19 V. |
| 5 | OFFSET N2 | Null adjustment terminal - second end of external trim pot; used with Pin 1 for offset nulling. |
| 6 | VCC+ | Positive supply rail - accepts up to +19 V; total supply current ≤5.6 mA across full temperature range. |
| 7 | OUT | Amplified output - drives loads ≥600 Ω; delivers ±13.5 V swing into 2 kΩ at room temperature. |
| 8 | NC | No connect - internally unconnected; must remain floating per TI design; not usable as heatsink pad. |
Key Features
| Feature | Design Value |
|---|---|
| Decompensated High-Speed Architecture | Enables 50 MHz GBW and 7.5 V/μs slew rate while maintaining precision - requires AV ≥ 5 for stability. |
| Excalibur Bipolar Process | Delivers 2.5 nV/√Hz noise at 1 kHz and 25 μV max VIO across −55°C to +125°C - superior to standard bipolar op amps. |
| Saturation Recovery Circuitry | Reduces overdrive recovery time to <1 µs - preserves signal integrity during transient overload in data acquisition systems. |
| Military Temperature Qualification | Rated for −55°C to +125°C operation with tested parameters including VIO, AVD, and CMRR - meets MIL-PRF-38535 requirements. |
| High PSRR and CMRR | 144 dB supply rejection and 131 dB common-mode rejection minimize errors from noisy power rails or ground shifts in industrial PLCs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA277MD | Unity-gain stable; 10 MHz GBW; 0.8 µV/°C VIO drift; lower noise (10 nV/√Hz) but slower speed. | Better for low-frequency, ultra-low-drift applications (e.g., digital multimeters); unsuitable for >1 MHz closed-loop designs. | Select OPA277MD when stability at AV = 1 is mandatory and bandwidth <1 MHz suffices. |
| LMH6629MF/NOPB | Unity-gain stable; 720 MHz GBW; 1.4 nV/√Hz noise; 20 V/μs slew; only rated to 85°C ambient. | Superior speed/noise for high-frequency RF/IF stages; lacks military temp rating and long-term VIO stability. | Select LMH6629MF/NOPB for commercial high-speed applications where −55°C to +125°C operation is not required. |
Compared with OPA277MD and LMH6629MF/NOPB, the TLE2037MD uniquely balances military-temperature operation, decompensated high-speed performance (50 MHz), and Excalibur-process low-noise precision - filling a niche where both extreme environment reliability and ≥5-MHz closed-loop bandwidth are non-negotiable.

FAQ
What is the minimum closed-loop gain required for stable operation of the TLE2037MD?
The TLE2037MD is decompensated and requires a minimum closed-loop gain of 5 to ensure phase margin ≥50° and prevent oscillation. This is explicitly specified in the datasheet's operating characteristics section and distinguishes it from unity-gain-stable variants like the TLE2027MD. Operating the TLE2037MD at AV < 5 risks instability and should be avoided in all designs using the TLE2037MD.
Does the TLE2037MD support rail-to-rail output swing?
The TLE2037MD does not provide rail-to-rail output swing. Its maximum output voltage swing is ±13.5 V into 2 kΩ at ±15 V supplies, and ±10 V into 600 Ω - meaning it saturates approximately 1.5 V below VCC+ and 1.5 V above VCC−. This limitation is inherent to its Excalibur bipolar output stage and must be accounted for in headroom calculations when using the TLE2037MD.
Can the OFFSET N1 and OFFSET N2 pins of the TLE2037MD be left unconnected?
Yes - the OFFSET N1 (Pin 1) and OFFSET N2 (Pin 5) pins of the TLE2037MD may be left unconnected with no impact on basic functionality. These terminals are provided solely for optional external offset nulling via a 10-kΩ potentiometer; omitting the trim network introduces no risk or performance penalty, and the TLE2037MD maintains its 25 μV max VIO specification without trimming.
Is the TLE2037MD pin-compatible with the TLE2027MD?
Yes - the TLE2037MD and TLE2027MD share identical 8-pin SOIC (D) packaging and pinout, including matching functions for all eight terminals (IN+, IN−, OUT, VCC+, VCC−, OFFSET N1, OFFSET N2, NC). However, they are not functionally interchangeable without circuit redesign due to the TLE2037MD's decompensated architecture requiring AV ≥ 5, whereas the TLE2027MD is unity-gain stable.
What is the maximum capacitive load the TLE2037MD can drive without compensation?
The TLE2037MD is characterized with a 100 pF capacitive load in standard test conditions (e.g., slew rate and GBW measurements), and TI specifies stable operation up to 100 pF with RL = 2 kΩ. Driving >100 pF directly risks peaking or ringing; for heavier loads, external isolation resistance (e.g., 50–100 Ω in series with the output) is recommended to maintain stability when using the TLE2037MD.
