Product details
Overview
TLE2027ID from Texas Instruments is a precision operational amplifier engineered for low-noise, high-speed analog signal conditioning in demanding industrial and test equipment applications. It delivers 25 μV max input offset voltage, 15 MHz unity-gain bandwidth, 3.3 nV/√Hz input voltage noise at 10 Hz, 45 V/μV large-signal open-loop gain (RL = 2 kΩ), and operates across −40°C to +105°C.
For engineers reviewing the TLE2027ID datasheet, TLE2027ID pinout, TLE2027ID application, or TLE2027ID equivalent, this device supports critical design tasks including precision sensor front-ends, high-fidelity data acquisition, low-drift instrumentation amplifiers, and wide-bandwidth active filters where dc accuracy and spectral purity must coexist.
Technical Context
The TLE2027ID uses TI's Excalibur bipolar process to achieve simultaneous high dc precision and ac performance. Its architecture includes saturation recovery circuitry for fast overdrive recovery and optimized internal compensation for stable unity-gain operation without external components.
It features rail-to-rail output swing capability (±12 V into 2 kΩ), 131 dB typical common-mode rejection ratio, and 144 dB typical supply-voltage rejection ratio - enabling robust operation in noisy, multi-rail systems with varying common-mode conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Unity-gain bandwidth | 15 MHz typical - enables stable closed-loop operation up to 15 MHz at AV = 1 for wideband filtering and signal reconstruction. |
| Input offset voltage (max) | 25 μV at TA = 25°C - ensures sub-100 μV total error budget in precision transducer interfaces without trimming. |
| Voltage noise density | 3.3 nV/√Hz at 10 Hz - minimizes low-frequency noise contribution in DC-coupled sensor amplification chains. |
| Open-loop gain (AVD) | 45 V/μV typical with RL = 2 kΩ - provides >133 dB loop gain at 1 kHz, supporting <0.001% linearity in 16-bit+ systems. |
| Supply voltage range | ±4 V to ±19 V - accommodates dual-supply industrial systems (±12 V, ±15 V) and allows headroom for transient suppression. |
| Operating temperature | −40°C to +105°C - qualified for under-hood automotive sensors, factory-floor PLC modules, and outdoor instrumentation. |
| CMRR / PSRR | 131 dB / 144 dB typical - rejects power supply ripple and common-mode interference in unshielded industrial environments. |
Pinout & Package
Package: 8-pin SOIC (Small Outline Integrated Circuit), D package, surface-mount, tape-and-reel compatible. Pin 1 marked by beveled corner or dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OFFSET N1 | Null adjustment terminal for manual offset trimming via external potentiometer. |
| 2 | IN− | Inverting input - high-impedance node for feedback network connection in standard op-amp configurations. |
| 3 | IN+ | Non-inverting input - accepts low-level sensor signals or reference voltages with minimal loading. |
| 4 | VCC− | Negative supply rail - must be decoupled locally with ≥0.1 μF ceramic capacitor to ground. |
| 5 | OFFSET N2 | Null adjustment terminal paired with Pin 1 for balanced offset calibration. |
| 6 | VCC+ | Positive supply rail - requires local 0.1 μF ceramic decoupling to suppress high-frequency supply noise. |
| 7 | OUT | Amplified output - capable of ±12 V swing into 2 kΩ load; drives ADC drivers, active filters, or level-shifting stages. |
| 8 | NC | No connect - internally unused; must remain floating per datasheet guidance. |
Key Features
| Feature | Design Value |
|---|---|
| Excalibur process technology | Enables simultaneous 25 μV offset and 15 MHz bandwidth - eliminates trade-off between precision and speed in single-supply alternatives. |
| Saturation recovery circuitry | Reduces overdrive recovery time to <1 μs - prevents settling errors in multiplexed sensor systems with rapid channel switching. |
| Low 1/f noise corner | 10 Hz corner frequency - maintains flat noise floor down to DC, critical for thermocouple and strain gauge amplification. |
| High open-loop gain stability | 45 V/μV min over full temperature range - ensures consistent loop gain in closed-loop designs across environmental extremes. |
| Industry-standard D package | SOIC-8 footprint - enables drop-in replacement of legacy precision op-amps (e.g., OP27, LT1028) without PCB redesign. |
Applications
| Strain Gauge Signal Conditioning | High-Fidelity Audio Preamp |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OP27GP | Higher 10 Hz noise (4.5 nV/√Hz), wider 2.8 μV/°C αVIO, but lower 0.8 pA/√Hz current noise. | Better suited for high-Z photodiode amps; less optimal for low-frequency strain gauge bridges due to higher drift. | Select OP27GP only when input bias current <100 pA is prioritized over low 1/f voltage noise and thermal drift. |
| LT1028ACN8#PBF | Lower 1.9 nV/√Hz noise at 1 kHz, but 100 μV max VIO and no offset null pins - lacks trim capability. | Ideal for wideband RF/IF gain blocks; unsuitable for precision DC-coupled systems requiring field calibration. | Choose LT1028ACN8#PBF for AC-coupled, high-frequency applications where offset trimming is unnecessary. |
Compared with OP27GP and LT1028ACN8#PBF, the TLE2027ID uniquely combines factory-trimmable offset (via Pins 1/5), industry-standard SOIC-8 packaging, and guaranteed 25 μV max VIO over extended temperature - making it the only option among the three qualified for calibrated, wide-temperature industrial instrumentation.

FAQ
What is the maximum operating temperature range for the TLE2027ID?
The TLE2027ID is characterized for operation from −40°C to +105°C, meeting industrial temperature grade requirements. This range is explicitly defined in the "recommended operating conditions" table of the SLOS192C datasheet and validated across all electrical parameters including offset voltage, CMRR, and open-loop gain.
Does the TLE2027ID require external compensation for unity-gain stability?
No, the TLE2027ID is internally compensated for unity-gain stability, with 55° phase margin at 15 MHz unity-gain bandwidth. Unlike the decompensated TLE2037 variant, the TLE2027ID does not require minimum closed-loop gain and may be used directly in voltage follower or inverting amplifier configurations without added compensation components.
Can the TLE2027ID drive a 600 Ω load effectively?
Yes, the TLE2027ID delivers ±10 V maximum output swing into 600 Ω loads, as specified in the "TLE20x7I electrical characteristics" table. Its ±50 mA absolute maximum output current rating supports this load, though thermal derating must be observed at elevated ambient temperatures per the Dissipation Rating Table for the D package.
How is offset voltage trimmed on the TLE2027ID?
Offset voltage is trimmed using Pins 1 (OFFSET N1) and 5 (OFFSET N2) with an external 10 kΩ potentiometer connected between them and VCC−. The wiper connects to VCC+, allowing adjustment of input stage bias currents to null VIO - a method confirmed in the "Pin Assignments" diagram and "Electrical Characteristics" section of the datasheet.
Is the TLE2027ID pin-compatible with the OP27 series?
Yes, the TLE2027ID uses the industry-standard 8-pin SOIC (D) package with identical pinout to the OP27GP, OP27G, and OP27F - including IN+, IN−, OUT, VCC+, VCC−, and offset null terminals. This enables direct PCB-level replacement in existing designs without layout modification.
