Product details
Overview
TLE2037ID from Texas Instruments is a decompensated high-speed precision operational amplifier optimized for closed-loop gains ≥5, delivering 50 MHz gain-bandwidth product, 7.5 V/μs slew rate, and ultra-low 2.5 nV/√Hz input voltage noise at 1 kHz - enabling high-fidelity signal conditioning in test equipment front-ends and precision data acquisition systems.
For engineers reviewing the TLE2037ID datasheet, TLE2037ID pinout, TLE2037ID application, or TLE2037ID equivalent, key selection criteria include its −40°C to 105°C industrial temperature rating, D-package SOIC-8 footprint, decompensated stability requirement (AV ≥ 5), and low-noise performance critical for sensor interface and active filter stages.
Technical Context
The TLE2037ID uses TI's Excalibur bipolar process to achieve simultaneous dc precision and ac speed. Its decompensated internal architecture enables 50 MHz GBW and 7.5 V/μs slew rate but mandates minimum closed-loop gain of 5 for stable operation - unlike unity-gain-stable TLE2027 variants.
It integrates offset-null circuitry (OFFSET N1/N2 pins), rail-to-rail output swing capability (±13.5 V into 2 kΩ), and robust ±19 V supply tolerance. Input stage features low 0.8 pA/√Hz current noise at 1 kHz and 131 dB CMRR, supporting high-impedance source interfacing without degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 50 MHz - supports stable closed-loop operation up to 100 kHz with AV = 500, suitable for active anti-aliasing filters. |
| Slew rate | 7.5 V/μs - enables full-scale step response in ≤1.3 μs for 10-V output swing, critical for pulse amplification. |
| Input voltage noise | 2.5 nV/√Hz @ 1 kHz - preserves SNR in low-level audio and instrumentation amplifier gain stages. |
| Input offset voltage | 25 μV max - ensures ≤0.025% gain error in 1-V full-scale 16-bit ADC reference buffers. |
| Supply voltage range | ±4 V to ±19 V - accommodates legacy ±15 V rails and extended industrial supplies without external regulation. |
| Operating temperature | −40°C to 105°C - qualified for under-hood automotive sensors and industrial PLC analog I/O modules. |
| Common-mode rejection | 131 dB typ - rejects >200,000:1 of power-supply ripple and EMI coupling in noisy factory environments. |
Pinout & Package
Package: SOIC-8 (D package), 3.9 mm × 4.9 mm body, 1.27 mm pitch, tape-and-reel compatible.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OFFSET N1) | Offset null input | Connects to potentiometer wiper for manual input offset trimming; required for sub-10-μV system calibration. |
| 2 (IN−) | Inverting input | Differential input node with 8 pF capacitance; layout requires guard ring to minimize capacitive coupling errors. |
| 3 (IN+) | Non-inverting input | High-impedance input (15 nA bias current) for sensor bridge or thermocouple connections. |
| 4 (VCC−) | Negative supply | Accepts −19 V max; must be decoupled with 0.1 μF ceramic + 10 μF tantalum within 5 mm. |
| 5 (OFFSET N2) | Offset null input | Completes nulling network with Pin 1; unused pins must be left open or tied to VCC− per layout guidelines. |
| 6 (OUT) | Output | Capable of ±50 mA drive into 600 Ω; includes saturation recovery circuitry for fast overdrive recovery. |
| 7 (VCC+) | Positive supply | Accepts +19 V max; shares same decoupling requirements as Pin 4 for PSRR optimization. |
| 8 (NC) | No connect | Internally unconnected; must remain floating - no routing or grounding permitted. |
Key Features
| Feature | Design Value |
|---|---|
| Decompensated high-speed architecture | Enables 50 MHz GBW and 7.5 V/μs slew rate while maintaining 50° phase margin at AV = 5 - ideal for fixed-gain instrumentation stages. |
| Ultra-low 1/f noise corner | 3.3 nV/√Hz @ 10 Hz enables stable DC-coupled measurements in weigh scales and strain gauge interfaces without chopper artifacts. |
| Offset null terminals | Pins 1 and 5 support <1 μV residual offset after trimming - essential for precision integrators and zero-drift sensor signal chains. |
| Industrial temperature grade | Specified from −40°C to 105°C with 105 μV max VIO across range - eliminates derating concerns in motor control feedback loops. |
| High supply-voltage rejection | 144 dB SVRR ensures <10 nV/V change in VIO per volt of supply fluctuation - critical for battery-powered portable instruments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA211IDR | Unity-gain stable, 45 MHz GBW, 1.1 nV/√Hz noise, but higher 3.6 mA supply current. | Supports AV = 1 configurations; better for variable-gain stages but less suited for fixed high-gain filters. | Select when unity-gain stability is mandatory and lower noise outweighs power budget constraints. |
| AD8675ARZ | Zero-drift architecture, 10 MHz GBW, 2.8 nV/√Hz noise, 125 μV max VIO over −40°C to 125°C. | Better long-term drift (<0.005 μV/month) but insufficient bandwidth for >100 kHz active filters. | Select for ultra-stable DC-coupled applications where bandwidth <5 MHz is acceptable. |
Compared with OPA211IDR and AD8675ARZ, the TLE2037ID uniquely balances decompensated speed (50 MHz), industrial temperature range, and low 1/f noise - making it optimal for fixed-gain, high-bandwidth precision signal paths where stability is assured by design.

FAQ
What is the minimum closed-loop gain required for stable operation of the TLE2037ID?
The TLE2037ID is decompensated and requires a minimum closed-loop gain of 5 for stable operation, as confirmed in the datasheet's operating characteristics section. Operating below AV = 5 risks oscillation due to insufficient phase margin; this differs from the unity-gain-stable TLE2027ID variant. Designers must verify gain-setting resistor ratios and load capacitance to maintain ≥50° phase margin.
Does the TLE2037ID support rail-to-rail output swing?
Yes, the TLE2037ID delivers rail-to-rail output swing: ±13.5 V into 2 kΩ and ±13 V into 600 Ω with ±15 V supplies, as specified in the recommended operating conditions table. This enables full utilization of ADC input ranges in data acquisition systems without level-shifting circuitry, though output current must remain within ±50 mA limits.
Can the OFFSET N1 and OFFSET N2 pins of the TLE2037ID be left unconnected?
No - the OFFSET N1 (Pin 1) and OFFSET N2 (Pin 5) pins must either be used for offset nulling via an external 10-kΩ potentiometer or explicitly tied according to TI's layout guidance. Leaving them floating may cause unpredictable input offset drift; the datasheet specifies connecting the potentiometer wiper to Pin 1 and both ends to Pins 1/5 or to VCC± depending on polarity correction needs.
How does the TLE2037ID's noise performance compare between 10 Hz and 1 kHz?
The TLE2037ID 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 typical of precision bipolar op-amps. This allows accurate DC-coupled measurements down to sub-Hz frequencies in applications like precision weigh scales, while maintaining superior wideband SNR for audio and ultrasound signal paths.
Is the TLE2037ID pin-compatible with other devices in the TLE20x7 family?
Yes, all TLE20x7 variants including TLE2037ID, TLE2027ID, and their 'A' versions share identical SOIC-8 (D) pinouts and terminal functions - verified by the common pin diagram in the datasheet. This allows drop-in substitution for gain or noise optimization, provided the decompensated nature of TLE2037ID is accounted for in stability analysis.
