Product details
Overview
TLE2037IDRG4 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), enabling high-fidelity signal conditioning in test equipment front-ends and precision data acquisition systems.
For engineers reviewing the TLE2037IDRG4 datasheet, TLE2037IDRG4 pinout, TLE2037IDRG4 application, or TLE2037IDRG4 equivalent, key selection criteria include its decompensated stability requirement (minimum gain = 5), −40°C to 105°C industrial temperature rating, SOIC-8 package with standard pinout, and Excalibur process–enabled low-noise/dc precision trade-off.
Technical Context
The TLE2037IDRG4 uses a decompensated internal compensation scheme that trades unity-gain stability for higher bandwidth and slew rate versus the TLE2027 series. Its 50 MHz gain-bandwidth product and 50° phase margin require minimum closed-loop gain of 5 to ensure stable operation.
Manufactured on TI's Excalibur bipolar process, it integrates saturation recovery circuitry for fast overdrive recovery and achieves 25 μV max input offset voltage with 131 dB typical CMRR and 144 dB typical PSRR - combining ac performance with dc precision previously unavailable in single op-amps.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 50 MHz - enables stable amplification up to 10 MHz at gain = 5, supporting wideband sensor signal conditioning. |
| 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 - critical for low-level audio, strain gauge, or thermocouple amplification where noise dominates SNR. |
| Input offset voltage | 25 μV max - ensures ≤0.025 mV error in 1 V full-scale precision measurement paths without trimming. |
| Common-mode rejection | 131 dB typ - rejects >2 million:1 common-mode interference in differential sensing applications (e.g., current shunt monitors). |
| Supply voltage range | ±4 V to ±19 V - accommodates dual-rail industrial supplies (±15 V) and extended-range systems (±18 V). |
| Operating temperature | −40°C to 105°C - qualified for under-hood automotive sensors, industrial PLC I/O modules, and outdoor instrumentation. |
Pinout & Package
Package: SOIC-8 (D package), tape-and-reel (R suffix), 1.27 mm pitch, 4.9 mm × 3.9 mm body size.
| 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 for feedback network connection in inverting configurations. |
| 3 | IN+ | Non-inverting input - referenced to system ground or bias voltage in non-inverting amplifiers and comparators. |
| 4 | VCC− | Negative supply rail - must be decoupled with 0.1 μF ceramic capacitor near pin for stability. |
| 5 | OFFSET N2 | Null adjustment terminal - connects to opposite end of trim pot for balanced offset nulling. |
| 6 | VCC+ | Positive supply rail - requires local 0.1 μF ceramic decoupling to suppress high-frequency supply noise. |
| 7 | OUT | Amplified output - drives loads ≥600 Ω; output swing limited to ±10 V (RL = 600 Ω) or ±11 V (RL = 2 kΩ). |
| 8 | NC | No connect - internally unconnected; must remain floating per TI design guidelines. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA211IDR | Unity-gain stable, 45 MHz GBW, 2.2 nV/√Hz noise, 0.1 μV/°C drift - lower noise but slower than TLE2037IDRG4. | Preferred for unity-gain buffer or low-drift DC-coupled systems where decompensation is undesirable. | Select OPA211IDR when stability at AV = 1 is required and 50 MHz bandwidth is not critical. |
| LT1028CS8#PBF | Unity-gain stable, 50 MHz GBW, 0.95 nV/√Hz noise, 1.2 μV/°C drift - superior noise but wider supply range (±4 V to ±18 V). | Better for ultra-low-noise front-ends (e.g., photodiode amps) where sub-1 nV/√Hz is mandatory. | Choose LT1028CS8#PBF when absolute minimum input voltage noise is prioritized over industrial temp range. |
Compared with OPA211IDR and LT1028CS8#PBF, the TLE2037IDRG4 uniquely balances decompensated speed (50 MHz, 7.5 V/μs) with industrial temperature qualification (−40°C to 105°C) and Excalibur process dc precision - making it optimal for high-bandwidth, high-reliability embedded systems where gain ≥5 is acceptable.

FAQ
What is the minimum closed-loop gain required for stable operation of the TLE2037IDRG4?
The TLE2037IDRG4 is decompensated and requires a minimum closed-loop gain of 5 to ensure stability. Operating at unity gain or gain = 2 will cause oscillation due to insufficient phase margin. This is explicitly stated in the datasheet's operating characteristics section and confirmed by the 50° phase margin measured only at AV ≥ 5.
Does the TLE2037IDRG4 support rail-to-rail input or output?
No, the TLE2037IDRG4 does not support rail-to-rail input or output. Its common-mode input voltage range is specified as −10.4 V to +10.4 V (with ±15 V supplies), and maximum output swing is ±10 V into 600 Ω or ±11 V into 2 kΩ - leaving ≥4 V headroom from either rail. This is consistent across all temperature grades.
Can the TLE2037IDRG4 replace the TLE2027IDRG4 in an existing design?
Yes, the TLE2037IDRG4 can replace the TLE2027IDRG4 only if the circuit's closed-loop gain is ≥5 and layout allows for its higher bandwidth. The TLE2027IDRG4 is unity-gain stable (15 MHz GBW), while the TLE2037IDRG4 (50 MHz GBW) requires gain ≥5. Swapping without verifying gain and compensation may cause instability.
What is the purpose of pins 1 and 5 (OFFSET N1 and OFFSET N2) on the TLE2037IDRG4?
Pins 1 and 5 are offset null terminals used to adjust input offset voltage via an external 10-kΩ potentiometer. The wiper connects to pin 1, one end to pin 5, and the other end to VCC−. This allows trimming VIO down to <1 μV in critical DC applications - a feature retained from the legacy OP-series op-amps.
Is the TLE2037IDRG4 RoHS compliant and lead-free?
Yes, the TLE2037IDRG4 is RoHS compliant and lead-free. Per Texas Instruments' packaging documentation, the SOIC-8 (D) package with R-suffix tape-and-reel uses lead-free matte tin plating and meets JEDEC J-STD-020 moisture sensitivity level 3 requirements.
