Product details
Overview
TLE2027CD from Texas Instruments is a low-noise, high-speed precision operational amplifier in an 8-pin SOIC (D) package, delivering 15 MHz unity-gain bandwidth, 2.5 nV/√Hz input voltage noise at 1 kHz, and 25 μV maximum input offset voltage at 25°C. It operates from ±4 V to ±19 V supplies and supports rail-to-rail output swing into 2 kΩ loads, making it suitable for high-fidelity signal conditioning in test equipment and medical instrumentation.
For engineers reviewing the TLE2027CD datasheet, TLE2027CD pinout, TLE2027CD application, or TLE2027CD equivalent, key selection criteria include its Excalibur-process-enabled dc precision (131 dB CMRR, 144 dB PSRR), saturation recovery circuitry, and stable unity-gain operation without external compensation - critical for low-distortion amplification in analog front-ends and precision data acquisition systems.
Technical Context
The TLE2027CD uses a proprietary Excalibur bipolar process to achieve simultaneous high dc accuracy and wide ac bandwidth. Its internal architecture includes matched transistor pairs for low offset drift and a composite gain stage enabling 15 MHz unity-gain bandwidth with 55° phase margin.
It features dedicated offset null pins (OFFSET N1, OFFSET N2), rail-to-rail output swing capability (±13.5 V into 2 kΩ), and built-in saturation recovery circuitry to minimize recovery time after overdrive - distinguishing it from standard precision op-amps lacking fast recovery.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Unity-gain bandwidth | 15 MHz typical - enables stable closed-loop operation at gains ≥1 with minimal phase lag in sensor interfaces. |
| Input voltage noise | 2.5 nV/√Hz at 1 kHz - ensures minimal added noise in low-frequency precision amplification (e.g., strain gauge, thermocouple). |
| Input offset voltage | 25 μV max at 25°C - reduces dc error in high-gain configurations without trimming, supporting 16-bit+ system accuracy. |
| CMRR | 131 dB typical - rejects common-mode interference in differential sensing applications like current shunt monitoring. |
| Supply voltage range | ±4 V to ±19 V - accommodates industrial ±15 V rails and extended-range systems without level-shifting. |
| Slew rate | 2.8 V/μs typical - supports clean amplification of signals up to ~30 kHz full-power bandwidth into 2 kΩ. |
| Operating temperature | 0°C to 70°C - qualified for commercial-grade embedded systems where ambient stability is assured. |
Pinout & Package
Package: 8-pin SOIC (Small Outline Integrated Circuit), D suffix, surface-mount, 150 mil width. Pin 1 marked by notch or dot; pin count and layout conform to JEDEC MS-012AC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OFFSET N1) | Offset null input | Connects to external potentiometer wiper for manual input offset adjustment; required for sub-10 μV system-level calibration. |
| 2 (IN−) | Inverting input | Differential input node; high-impedance (8 pF capacitance) and matched to IN+ for optimal CMRR performance. |
| 3 (IN+) | Non-inverting input | Differential input node; internally matched to IN− to maintain 131 dB CMRR across temperature. |
| 4 (VCC−) | Negative supply rail | Accepts −4 V to −19 V; must be decoupled locally to suppress supply-induced noise coupling into sensitive inputs. |
| 5 (OFFSET N2) | Offset null reference | Completes offset nulling circuit with Pin 1; tied to VCC− or mid-supply depending on configuration. |
| 6 (OUT) | Amplifier output | Capable of ±13.5 V swing into 2 kΩ; includes saturation recovery logic to exit overload in <1 μs. |
| 7 (VCC+) | Positive supply rail | Accepts +4 V to +19 V; requires low-ESR ceramic decoupling (0.1 μF) within 5 mm of pin for stability. |
| 8 (NC) | No connect | Internally unconnected; must remain floating - no routing or grounding permitted to avoid parasitic coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Excalibur process technology | Enables 25 μV VIO max and 0.4 μV/°C tempco simultaneously - eliminates need for auto-zero or chopper stabilization in many applications. |
| Saturation recovery circuitry | Reduces overload recovery time to <1 μs - preserves signal integrity in transient-heavy environments like pulse amplification or fault detection. |
| Rail-to-rail output swing | Delivers ±13.5 V into 2 kΩ load with <0.1% THD - maximizes dynamic range without external level-shifting components. |
| High PSRR (144 dB) | Rejects supply ripple >100 dB below signal level - allows direct use with noisy switch-mode power supplies in portable instrumentation. |
| Offset null pins | Enable <5 μV residual offset after calibration - supports metrology-grade accuracy without laser trimming or digital correction. |

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 | Lower noise (1.1 nV/√Hz), higher GBW (45 MHz), but no offset null pins and 25°C-only VIO spec (150 μV max). | Better for wideband AC-coupled applications; unsuitable where manual offset trim or guaranteed 25 μV max over full temp range is required. | Select OPA211IDR only if noise and speed outweigh need for guaranteed low offset and field calibration capability. |
| AD8675ARZ | Zero-drift architecture, 10 μV VIO max, but lower bandwidth (10 MHz) and higher 1/f noise corner (~10 Hz). | Ideal for ultra-low-offset DC applications (e.g., precision weigh scales); not recommended for >10 kHz signal paths due to limited slew rate (2.5 V/μs). | Choose AD8675ARZ when long-term dc stability dominates over ac performance; avoid in high-frequency sensor interfaces. |
Compared with OPA211IDR and AD8675ARZ, the TLE2027CD uniquely balances guaranteed 25 μV VIO across 0°C–70°C, 15 MHz bandwidth, and user-adjustable offset - making it optimal for calibrated, wideband precision systems where both dc accuracy and ac fidelity are non-negotiable.

FAQ
What is the maximum operating temperature range for the TLE2027CD?
The TLE2027CD is characterized for operation from 0°C to 70°C, as indicated by its "C" temperature-suffix designation. It meets all electrical specifications across this commercial temperature range, including 25 μV maximum input offset voltage and 15 MHz unity-gain bandwidth. Operation outside this range is not guaranteed and may result in degraded performance or parametric failure. The TLE2027CD does not support extended industrial or military temperature grades.
Does the TLE2027CD require external compensation for unity-gain stability?
No, the TLE2027CD is internally compensated for unity-gain stability and exhibits 55° phase margin at 15 MHz with a 2 kΩ load and 100 pF capacitive load. Unlike the decompensated TLE2037 variant, the TLE2027CD does not require minimum closed-loop gain and can be used directly in voltage-follower or gain-of-one configurations without external components. This simplifies design in precision buffer and active filter applications.
How is offset nulling implemented on the TLE2027CD?
The TLE2027CD provides two dedicated offset null terminals: Pin 1 (OFFSET N1) and Pin 5 (OFFSET N2). A 10 kΩ potentiometer is connected between these pins, with its wiper grounded. Adjusting the potentiometer balances internal input-stage mismatches, reducing input offset voltage to <5 μV. This manual calibration is essential in metrology-grade systems where factory-trimmed offset alone is insufficient for target accuracy.
Can the TLE2027CD drive capacitive loads without oscillation?
The TLE2027CD is stable with up to 100 pF total capacitive load (including PCB trace and fixture capacitance) when driving a 2 kΩ resistive load, as verified in Figure 1 of the datasheet. For larger capacitive loads (>100 pF), isolation resistance (e.g., 50 Ω in series with the output) is required to maintain phase margin. Driving coaxial cables or ADC input capacitors exceeding 100 pF without isolation risks peaking or oscillation due to pole-splitting effects.
What is the supply current consumption of the TLE2027CD under typical conditions?
The TLE2027CD draws 3.8 mA typical supply current per amplifier (ICC) with ±15 V supplies, no load, and VO = 0 V at 25°C. Supply current remains stable across temperature (5.6 mA max over 0°C–70°C) and varies less than ±5% with supply voltage from ±4 V to ±19 V. This predictable quiescent current simplifies power budgeting in multi-channel precision systems and enables accurate thermal modeling.
