Product details
Overview
TLE2037MDG4 from Texas Instruments is a decompensated, high-speed 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 (−55°C to 125°C), and operates on ±4 V to ±19 V supplies. It serves in low-noise instrumentation front-ends requiring wide bandwidth and dc stability.
For engineers reviewing the TLE2037MDG4 datasheet, TLE2037MDG4 pinout, TLE2037MDG4 application, or TLE2037MDG4 equivalent, key selection criteria include its decompensated architecture requiring minimum gain of 5, military-grade temperature range (−55°C to 125°C), SOIC-8 packaging, and trade-off between speed (50 MHz GBW) and stability versus the compensated TLE2027 series.
Technical Context
The TLE2037MDG4 uses TI's Excalibur bipolar process to achieve simultaneous low noise and high dc precision. Its decompensated internal compensation enables 50 MHz gain-bandwidth and 7.5 V/μs slew rate, but mandates closed-loop gain ≥5 for phase margin ≥50°. Input stage features matched transistors for 25 μV max VIO over full military temperature range.
It integrates saturation recovery circuitry to minimize output overload recovery time and supports rail-to-rail input common-mode range (±10.3 V at full temp range). The device maintains 131 dB typical CMRR and 144 dB typical PSRR, enabling high-accuracy signal conditioning in noisy supply environments.
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 fast transient response in active filters and precision DAC output buffers without distortion. |
| Input voltage noise | 2.5 nV/√Hz @ 1 kHz - Low enough for sub-μV-level signal amplification in medical EEG or strain-gauge interfaces. |
| Input offset voltage | 25 μV max (−55°C to 125°C) - Ensures <100 μV total drift in uncalibrated military/aerospace systems over full operating range. |
| Supply voltage range | ±4 V to ±19 V - Compatible with legacy ±15 V industrial rails and extended-range analog backplanes. |
| Common-mode input range | ±10.3 V @ −55°C to 125°C - Allows direct interfacing to ±10 V sensor outputs without level-shifting. |
| Phase margin | 50° @ unity gain - Confirms conditional stability; requires gain ≥5 for robust operation per datasheet Figure 4. |
Pinout & Package
Package: SOIC-8 (D package), surface-mount, 150 mil width, tape-and-reel compatible (R suffix option).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OFFSET N1 | Null offset adjustment terminal; used with external potentiometer to trim input offset voltage to zero. |
| 2 | IN− | Inverting input; high-impedance node for feedback network connection in standard op-amp configurations. |
| 3 | IN+ | Non-inverting input; accepts differential or single-ended signal sources with ±10.3 V common-mode range. |
| 4 | VCC− | Negative supply rail; must be decoupled locally to suppress ground bounce in high-slew-rate operation. |
| 5 | OFFSET N2 | Second null offset terminal; paired with Pin 1 for symmetric trimming of input stage mismatch. |
| 6 | OUT | Amplified output; capable of ±11 V swing into 2 kΩ load, with saturation recovery circuitry for fast overload recovery. |
| 7 | VCC+ | Positive supply rail; requires low-ESR ceramic decoupling (0.1 μF) adjacent to pin for stability at 50 MHz. |
| 8 | NC | No connect; internally unused; must remain unconnected to avoid parasitic coupling or EMI ingress. |
Key Features
| Feature | Design Value |
|---|---|
| Decompensated high-speed architecture | Enables 50 MHz GBW and 7.5 V/μs slew rate while maintaining precision-requires minimum closed-loop gain of 5 for stability. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA277MDREPG4 | Unity-gain stable, 10 MHz GBW, 0.8 μV/°C VIO drift, SOIC-8, ±22 V max supply | Better dc precision and lower drift, but 5× slower; suited for pure dc/low-frequency applications only | Select when stability at G = 1 is mandatory and bandwidth <2 MHz suffices. |
| AD8675ARZ | Unity-gain stable, 10 MHz GBW, 2.8 nV/√Hz noise @ 1 kHz, SOIC-8, rail-to-rail output | Lower noise floor than OPA277 but higher than TLE2037MDG4; no offset null pins | Choose when rail-to-rail output swing is required and offset trimming is unnecessary. |
Compared with OPA277MDREPG4 and AD8675ARZ, the TLE2037MDG4 uniquely delivers military-temperature-rated 50 MHz bandwidth with offset nulling-making it irreplaceable in high-speed, high-stability, wide-temperature instrumentation where gain ≥5 is acceptable.

FAQ
What is the minimum closed-loop gain required for stable operation of the TLE2037MDG4?
The TLE2037MDG4 is decompensated and requires a minimum closed-loop gain of 5 to ensure phase margin ≥50° and prevent oscillation. This is explicitly mandated in the datasheet's operating characteristics section and verified in Figure 4 test circuit. Using the TLE2037MDG4 at unity gain or gain <5 risks instability and should be avoided unless external compensation is applied.
Does the TLE2037MDG4 support offset voltage trimming, and how is it implemented?
Yes, the TLE2037MDG4 supports precision offset trimming via Pins 1 (OFFSET N1) and 5 (OFFSET N2). A 20-kΩ potentiometer is connected between these pins with its wiper grounded, allowing adjustment of input stage imbalance. This capability is confirmed in the D-package pin diagram and functional description, enabling <5 μV residual offset after calibration in high-accuracy systems.
What is the maximum output voltage swing of the TLE2037MDG4 at full military temperature range?
At −55°C to 125°C, the TLE2037MDG4 delivers ±11 V maximum output swing into a 2 kΩ load with ±15 V supplies, as specified in the TLE20x7M electrical characteristics table. This is reduced to ±10 V into 600 Ω loads due to output stage limitations, and all values are guaranteed across the full temperature range-not just at 25°C.
How does the noise performance of the TLE2037MDG4 compare between 10 Hz and 1 kHz?
The TLE2037MDG4 exhibits 3.3 nV/√Hz input voltage noise at 10 Hz and 2.5 nV/√Hz at 1 kHz, confirming a low 1/f noise corner below 10 Hz. This dual-point specification-verified in TLE20x7M operating characteristics-is critical for applications like precision DC amplification where low-frequency drift dominates error budgets.
Is the TLE2037MDG4 pin-compatible with the TLE2027MDG4, and what are the key functional differences?
Yes, the TLE2037MDG4 and TLE2027MDG4 share identical SOIC-8 pinouts and pin functions. However, the TLE2037MDG4 is decompensated (50 MHz GBW, 7.5 V/μs) versus the compensated TLE2027MDG4 (13 MHz GBW, 2.8 V/μs), and requires minimum gain = 5. Both offer 25 μV max VIO over −55°C to 125°C, but only the TLE2037MDG4 supports high-speed precision use cases.
