Product details
Overview
TLE2027CDR from Texas Instruments is a single-channel Excalibur low-noise high-speed precision operational amplifier in an 8-pin SOIC (D) package. It delivers 15 MHz unity-gain bandwidth, 2.5 nV/√Hz input voltage noise at 1 kHz, 25 μV max input offset voltage (0°C to 70°C), and 45 V/μV large-signal open-loop gain with RL = 2 kΩ - enabling high-fidelity signal conditioning in precision instrumentation front-ends.
For engineers reviewing the TLE2027CDR datasheet, TLE2027CDR pinout, TLE2027CDR application, or TLE2027CDR equivalent, key selection criteria include its 3.3 nV/√Hz 10-Hz noise floor, saturation recovery circuitry for fast overdrive recovery, ±4 V to ±19 V supply flexibility, and compatibility with standard 8-pin SOIC PCB footprints used in test equipment and medical sensor interfaces.
Technical Context
The TLE2027CDR uses TI's Excalibur bipolar process to achieve simultaneous dc precision and ac performance unattainable in earlier op-amps. Its architecture integrates offset-nulling circuitry, low-noise input transistors, and internal compensation for stable unity-gain operation without external components.
It features dedicated OFFSET N1 and OFFSET N2 pins for external trimming, rail-to-rail output swing capability (±13.5 V into 2 kΩ), and robust common-mode rejection (131 dB typ) and supply-voltage rejection (144 dB typ) - critical for low-drift amplification in noisy industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Unity-Gain Bandwidth | 15 MHz typical - supports stable closed-loop amplification up to audio and low-RF frequencies without phase-margin degradation. |
| Input Voltage Noise | 2.5 nV/√Hz at 1 kHz - enables sub-μV signal resolution in low-frequency precision measurement paths. |
| Input Offset Voltage | 25 μV maximum (0°C to 70°C) - ensures ≤ 0.001% gain error in 1-V full-scale 16-bit data acquisition systems. |
| Open-Loop Gain | 45 V/μV typical with RL = 2 kΩ - provides >133 dB loop gain at DC for <1 ppm linearity error in precision integrators. |
| Supply Voltage Range | ±4 V to ±19 V - accommodates dual-supply industrial rails (±5 V, ±12 V, ±15 V) and wide-input-range sensor signal chains. |
| Common-Mode Rejection | 131 dB typical - rejects >2 million:1 of power-supply or ground-bounce interference in differential sensing. |
| Saturation Recovery Time | Integrated circuitry enables rapid exit from output rail-clamp states - critical for pulse-amplifier and multiplexed ADC driver applications. |
Pinout & Package
Package: 8-pin SOIC (Small Outline Integrated Circuit), D package, tape-and-reel (R suffix). Body dimensions: 4.9 mm × 3.9 mm × 1.75 mm, standard JEDEC MS-012AC footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OFFSET N1) | Offset null input | Connects to external potentiometer wiper for manual input offset trimming; required for ultra-low-drift calibration. |
| 2 (IN−) | Inverting input | Differential input node with 8 pF capacitance and ±1.2 V max differential voltage rating. |
| 3 (IN+) | Non-inverting input | Differential input node; common-mode range extends to ±10.5 V at full temperature range. |
| 4 (VCC−) | Negative supply rail | Accepts −4 V to −19 V; total current out ≤ 50 mA; thermal design must account for 725 mW max dissipation at 25°C. |
| 5 (OFFSET N2) | Offset null input | Completes external trimming network; paired with Pin 1 to adjust input stage quiescent point. |
| 6 (OUT) | Amplified output | Capable of ±13.5 V swing into 2 kΩ; drives capacitive loads ≤100 pF stably; short-circuit protected. |
| 7 (VCC+) | Positive supply rail | Accepts +4 V to +19 V; total current in ≤ 50 mA; decoupling recommended within 1 cm of pin. |
| 8 (NC) | No connect | Internally unused; must remain unconnected per TI design guidelines to avoid parasitic coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Excalibur process technology | Enables 25 μV max VIO and 2.5 nV/√Hz noise simultaneously - eliminates trade-off between precision and bandwidth in legacy bipolar op-amps. |
| External offset null terminals | Pins 1 and 5 support <1 μV residual offset after trimming - essential for strain-gauge and thermopile amplifier zero-point stability. |
| Saturation recovery circuitry | Reduces overdrive recovery time by >10× vs. standard op-amps - prevents settling errors in fast-pulse amplification (e.g., laser diode drivers). |
| High CMRR & PSRR | 131 dB CMRR and 144 dB PSRR minimize error from shared supply/ground impedance in multi-channel systems. |
| Wide supply range | ±4 V to ±19 V operation allows direct interface with legacy ±5 V, ±12 V, and ±15 V analog subsystems without level-shifting. |

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 1.1 nV/√Hz noise at 1 kHz but higher 1.1 mA supply current; no offset null pins. | Better for ultra-low-noise, low-power battery-operated sensors; unsuitable where manual offset trim is required. | Select OPA211IDR when noise dominates over trim flexibility and power budget permits. |
| AD8675ARZ | Zero-drift architecture; 10 μV max VIO and 2.8 nV/√Hz noise; rail-to-rail output; no offset null pins. | Superior long-term drift stability for DC-coupled integrators; lacks saturation recovery and external trim capability. | Select AD8675ARZ for applications demanding <0.1 μV/°C drift but not requiring overdrive recovery or manual calibration. |
Compared with OPA211IDR and AD8675ARZ, the TLE2027CDR uniquely combines factory-trimmed precision, user-accessible offset nulling, saturation recovery, and proven 15-MHz bandwidth - making it the only choice for repairable, field-calibratable precision analog systems operating across 0°C to 70°C.

FAQ
What is the maximum operating temperature range for the TLE2027CDR?
The TLE2027CDR is characterized for operation from 0°C to 70°C (C-suffix device). Its absolute maximum junction temperature is 150°C, and it supports continuous operation up to 70°C ambient with appropriate PCB copper area and airflow. Derating begins above 25°C at 5.8 mW/°C for the SOIC (D) package.
Does the TLE2027CDR require external compensation for unity-gain stability?
No, the TLE2027CDR is internally compensated for unity-gain stability with 55° phase margin at 15 MHz. Unlike the decompensated TLE2037 variant, it does not require minimum closed-loop gain and can be used directly as a voltage follower or in gain-of-one configurations without external capacitors.
Can the TLE2027CDR drive a 600 Ω load effectively?
Yes, the TLE2027CDR delivers ±10 V maximum peak output swing into 600 Ω loads and maintains <0.002% THD at 10 V output. Its 45 V/μV open-loop gain ensures minimal gain error (<0.02%) under this load, making it suitable for professional audio line-driving applications.
How is offset voltage trimmed on the TLE2027CDR?
Offset voltage is trimmed using external circuitry connected between Pins 1 (OFFSET N1) and 5 (OFFSET N2). A 10-kΩ potentiometer with wiper to VCC− and ends to these pins adjusts the input stage bias, reducing residual offset to <1 μV after calibration - a capability not found in modern zero-drift op-amps.
Is the TLE2027CDR RoHS compliant and lead-free?
Yes, the TLE2027CDR is RoHS compliant and lead-free per TI's SLOS192C datasheet revision April 2010. The SOIC (D) package uses matte tin lead finish, and the device meets JEDEC J-STD-020 moisture sensitivity level 3 (MSL-3) requirements.
