Product details
Overview
TLE2037AMDG4 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, and ultra-low input voltage noise (2.5 nV/√Hz at 1 kHz) in an 8-pin SOIC package. Designed for low-noise signal conditioning in test equipment, medical instrumentation, and high-fidelity data acquisition systems.
For engineers reviewing the TLE2037AMDG4 datasheet, TLE2037AMDG4 pinout, TLE2037AMDG4 application, or TLE2037AMDG4 equivalent, key selection criteria include its decompensated stability requirement (minimum gain = 5), military-grade temperature range (−55°C to 125°C), and Excalibur process–enabled dc precision with 25 μV max input offset voltage.
Technical Context
The TLE2037AMDG4 uses a decompensated internal compensation scheme that trades unity-gain stability for higher bandwidth and slew rate versus the TLE2027AMDG4. Its architecture supports stable operation only when configured with closed-loop gain ≥5, as confirmed by 50° phase margin at unity gain and 50 MHz GBW under RL = 2 kΩ, CL = 100 pF conditions.
Manufactured on TI's Excalibur bipolar process, it integrates saturation recovery circuitry for fast overdrive recovery and achieves 131 dB typical CMRR and 144 dB typical PSRR - enabling high-accuracy amplification in noisy industrial environments with wide supply ranges (±4 V to ±19 V).
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 interfaces. |
| Slew Rate | 7.5 V/μs - supports clean 10 Vpp output at >1 MHz without slewing distortion in active filters or DAC buffers. |
| Input Voltage Noise | 2.5 nV/√Hz at 1 kHz - ensures minimal added noise in low-level transducer signal chains (e.g., strain gauges, thermopiles). |
| Input Offset Voltage | 25 μV max (−55°C to 125°C) - maintains dc accuracy in uncalibrated precision measurement front-ends. |
| Supply Voltage Range | ±4 V to ±19 V - accommodates dual-rail industrial systems including ±15 V legacy analog infrastructure. |
| Common-Mode Input Range | ±10.3 V (full temp range) - allows direct interfacing to ±10 V sensor outputs without level-shifting. |
| Phase Margin | 50° at unity gain - mandates minimum closed-loop gain of 5; violates stability if used in unity-gain follower configuration. |
Pinout & Package
Package: 8-pin SOIC (D package), surface-mount, tape-and-reel compatible (R suffix available). Pin 1 marked via dot or bevelled edge; standard industry pinout aligning with LM741/LM358 footprint compatibility for layout reuse.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OFFSET N1 | Null adjustment terminal - connects to potentiometer wiper for manual input offset trimming. |
| 2 | IN− | Inverting input - high-impedance node; requires matched trace routing to minimize common-mode error. |
| 3 | IN+ | Non-inverting input - referenced to system ground or bias network; sensitive to EMI coupling. |
| 4 | VCC− | Negative supply rail - must be decoupled with 0.1 μF ceramic capacitor placed ≤5 mm from pin. |
| 5 | OFFSET N2 | Null adjustment terminal - other end of offset trim potentiometer; forms balanced null network with Pin 1. |
| 6 | OUT | Amplified output - capable of ±11 V swing into 2 kΩ load; avoid capacitive loads >100 pF without isolation resistor. |
| 7 | VCC+ | Positive supply rail - decoupling identical to Pin 4; shared ground plane with VCC− improves PSRR. |
| 8 | NC | No connect - internally unconnected; must remain floating (no tie to ground or supply). |
Key Features
| Feature | Design Value |
|---|---|
| Decompensated High-Speed Architecture | Enables 50 MHz GBW and 7.5 V/μs slew rate - 3.3× faster than compensated TLE2027AMDG4 for gain ≥5 circuits. |
| Excalibur Bipolar Process | Delivers 25 μV max VIO over −55°C to 125°C - eliminates need for factory calibration in military/aerospace modules. |
| Saturation Recovery Circuitry | Reduces overload recovery time to <1 μs - preserves signal integrity during transient overvoltage events in protection circuits. |
| Low 1/f Noise Corner | 3.3 nV/√Hz at 10 Hz - maintains SNR in sub-100 Hz biomedical applications (ECG, EEG) without chopper stabilization. |
| MIL-PRF-38535 Qualified (M-suffix) | Complies with screening requirements for Class B or S devices - supports qualification per DO-254 and MIL-STD-883. |
Applications
| High-Fidelity Data Acquisition | Medical Instrumentation Signal Chain |
|---|---|
Use Scenario: Amplifying low-amplitude, high-impedance signals from piezoelectric sensors in portable vibration analyzers. IC Role / Device Role / Timing Role: Primary gain stage with fixed gain = 10, driving 16-bit SAR ADC input.

IC Role / Device Role / Timing Role: Instrumentation amplifier first stage (gain = 100) with active filtering. Use Value: 25 μV max VIO avoids baseline drift over temperature; saturation recovery prevents waveform clipping during muscle artifact. |
| Test & Measurement Equipment | Industrial Process Control Loop |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA211IDR | Unity-gain stable, 45 MHz GBW, 2.2 nV/√Hz noise, but only rated for −40°C to 125°C (not −55°C). | Acceptable for commercial/industrial designs lacking extended cold-start requirements. | Select when unity-gain stability is mandatory and military temperature range is not required. |
| AD8620ARZ | FET-input, 25 MHz GBW, 4.2 nV/√Hz noise, rail-to-rail output, but 125 μV max VIO over full temperature range. | Better for high-Z source buffering; insufficient dc precision for calibrated measurement paths. | Select for ultra-low input bias current (1 pA) applications where noise and speed are secondary to input impedance. |
Compared with OPA211IDR and AD8620ARZ, the TLE2037AMDG4 uniquely combines military-temperature operation, decompensated speed, and sub-30 μV dc precision - making it irreplaceable in calibrated aerospace DAQ systems where gain ≥5 topology is acceptable.

FAQ
Can the TLE2037AMDG4 be used in a unity-gain buffer configuration?
No. The TLE2037AMDG4 is decompensated and requires a minimum closed-loop gain of 5 for stability, as verified by its 50° phase margin at unity gain. Using it as a unity-gain follower risks oscillation and unpredictable output behavior. For unity-gain applications, select the TLE2027AMDG4 or OPA211IDR instead.
What is the maximum allowable capacitive load for the TLE2037AMDG4 output?
The TLE2037AMDG4 drives up to 100 pF directly, as tested in the datasheet with CL = 100 pF. Driving larger capacitive loads (e.g., ADC inputs, cables) requires an isolation resistor (≥100 Ω) between the output and capacitance to maintain phase margin and prevent peaking or ringing.
Does the TLE2037AMDG4 support single-supply operation?
Yes - though optimized for dual supplies, the TLE2037AMDG4 operates with total supply voltage from 8 V to 38 V. For single-supply use (e.g., +15 V and GND), bias the IN+ input to mid-rail using a resistor divider and ensure the common-mode input range (−10.3 V to +10.3 V referenced to VCC−) remains satisfied relative to the negative rail (GND).
How does the TLE2037AMDG4 differ from the TLE2037MDG4?
The TLE2037AMDG4 specifies 25 μV max input offset voltage over −55°C to 125°C, while the TLE2037MDG4 specifies 100 μV max. Both share identical decompensated architecture, 50 MHz GBW, and military temperature rating - but the "A" grade provides tighter dc precision for calibrated systems where offset drift must be minimized.
Is the NC pin (Pin 8) safe to connect to ground or supply?
No. Pin 8 is explicitly designated as "NC" (No Connect) in the datasheet and internal schematic. It is not bonded and has no internal connection. Connecting it to any potential may introduce leakage paths or parasitic coupling; it must remain unconnected and unstubbed on the PCB.
