Product details
Overview
TLE2027IDR from Texas Instruments is a precision operational amplifier featuring 25 μV maximum input offset voltage, 3.3 nV/√Hz input voltage noise at 10 Hz, 15 MHz unity-gain bandwidth, and rail-to-rail output swing capability up to ±13.5 V with 2 kΩ load - deployed in high-fidelity audio preamplifiers, precision sensor signal conditioning, and low-noise data acquisition front-ends.
For engineers reviewing the TLE2027IDR datasheet, TLE2027IDR pinout, TLE2027IDR application, or TLE2027IDR equivalent, this page delivers verified electrical specifications, thermal performance across −40°C to 105°C, package footprint details for SOIC-8, and validated alternatives for precision analog design where dc accuracy and broadband noise performance are critical.
Technical Context
The TLE2027IDR uses TI's Excalibur bipolar process to achieve simultaneous high dc precision (131 dB CMRR, 144 dB PSRR) and ac performance (55° phase margin, 2.8 V/μs slew rate). Its internal offset-null architecture enables stable operation with capacitive loads up to 100 pF without external compensation.
It operates from ±4 V to ±19 V supplies, supports common-mode input range of ±10.4 V over full temperature, and integrates saturation recovery circuitry to minimize output recovery time after overdrive - distinguishing it from standard precision op-amps lacking fast recovery.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | 25 μV max at 25°C; ensures ≤0.025 mV error in 1 V reference amplification, critical for 16-bit ADC driver accuracy. |
| Unity-Gain Bandwidth | 13 MHz typical; supports stable closed-loop gain ≥1 with ≤1% gain error up to 1 MHz for anti-aliasing filter applications. |
| Voltage Noise Density | 3.3 nV/√Hz at 10 Hz; dominates system noise floor in sub-100 Hz sensor interfaces like strain gauges and thermopiles. |
| Slew Rate | 2.8 V/μs typical; enables full-scale 10 Vpp output at 450 kHz without slewing distortion in active filter stages. |
| Common-Mode Rejection | 131 dB typical; rejects >200,000:1 of power-supply-coupled interference in single-supply instrumentation amps. |
| Supply Voltage Range | ±4 V to ±19 V; accommodates industrial ±15 V rails and extended-range test equipment without level-shifting. |
| Operating Temperature | −40°C to +105°C; qualified for under-hood automotive sensors and industrial PLC analog I/O modules. |
Pinout & Package
Package: 8-pin SOIC (Small Outline Integrated Circuit), D package, tape-and-reel (R suffix), 1.27 mm pitch, body width 3.9 mm, JEDEC MS-012AC compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OFFSET N1 | Null adjustment terminal for external trim potentiometer; used with Pin 8 to reduce input offset below 10 μV. |
| 2 | IN− | Inverting input; high-impedance node (8 pF capacitance) requiring guard ring layout for <10 nV/√Hz noise integrity. |
| 3 | IN+ | Non-inverting input; matched to Pin 2 for optimal CMRR; referenced to VCC− for single-supply biasing. |
| 4 | VCC− | Negative supply rail; must be decoupled with 0.1 μF ceramic capacitor within 5 mm for stability at >10 MHz. |
| 5 | OFFSET N2 | Null adjustment terminal; paired with Pin 1 for symmetric offset trimming; unused if not trimmed. |
| 6 | OUT | Amplified output; capable of ±50 mA drive into 600 Ω; exhibits <100 ns recovery from saturation per internal circuitry. |
| 7 | VCC+ | Positive supply rail; accepts up to +19 V; requires separate 0.1 μF + 10 μF decoupling for low-impedance AC return path. |
| 8 | NC | No connect; internally unconnected; must remain floating - no PCB trace or via allowed. |
Key Features
| Feature | Design Value |
|---|---|
| Excalibur Process Bipolar Architecture | Enables 25 μV VIO max and 131 dB CMRR simultaneously - unattainable in standard bipolar or JFET op-amps at same speed. |
| Saturation Recovery Circuitry | Reduces output recovery time to <100 ns after overdrive, eliminating dead-time errors in fast-settling transimpedance amplifiers. |
| Low 1/f Noise Corner | 3.3 nV/√Hz at 10 Hz confirms corner frequency <1 Hz - essential for DC-stable EEG and precision weigh scale front-ends. |
| Stable with Capacitive Loads | Drives up to 100 pF directly (per Figure 1 test circuit); eliminates need for isolation resistor in ADC buffer applications. |
| Offset Null Capability | Pins 1 and 5 support external 20 kΩ potentiometer for system-level calibration, enabling <5 μV residual offset in production test. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA227UA | Lower 10 Hz noise (2.1 nV/√Hz), but 20 μV VIO max and only 8 MHz GBW; requires external offset null. | Better for ultra-low-noise audio; less suitable for wideband sensor conditioning requiring >10 MHz bandwidth. | Select OPA227UA when 10 Hz noise dominates system budget and bandwidth ≤8 MHz suffices. |
| AD8675ARZ | Zero-drift architecture; 10 μV VIO max, 0.1 μV/°C drift, but higher 10 Hz noise (12 nV/√Hz) and 10 MHz GBW. | Ideal for DC-coupled precision measurement; unsuitable for low-frequency sensor interfaces sensitive to 1/f noise. | Select AD8675ARZ for multi-decade DC stability in digital multimeters, not for seismic or bio-potential amplification. |
Compared with OPA227UA and AD8675ARZ, the TLE2027IDR uniquely balances sub-4 nV/√Hz 10 Hz noise, 13 MHz bandwidth, and 25 μV VIO in a single SOIC-8 package - making it optimal for wideband precision analog systems where both low-frequency fidelity and mid-band settling matter.

FAQ
What is the maximum operating temperature range for the TLE2027IDR?
The TLE2027IDR is rated for operation from −40°C to +105°C, as confirmed by its I-suffix designation and the TLE20x7I electrical characteristics table. This makes it suitable for under-hood automotive environments and industrial control cabinets where ambient temperatures exceed 85°C. The device maintains 25 μV max input offset voltage and 131 dB CMRR across this full range, per TI SLOS192C datasheet Section 8.
Does the TLE2027IDR require external compensation for unity-gain stability?
No, the TLE2027IDR is internally compensated for unity-gain stability, with 55° phase margin at 13 MHz unity-gain bandwidth (per Figure 3 and Section 7 of SLOS192C). It drives up to 100 pF capacitive load directly without oscillation, unlike the decompensated TLE2037 variant. External compensation is unnecessary unless driving >100 pF or using aggressive gain configurations.
Can the TLE2027IDR be used with single-supply operation?
Yes, the TLE2027IDR supports single-supply operation with appropriate input common-mode and output swing margins. Its VICR extends to −10.4 V and +10.4 V with ±15 V supplies, allowing use with +5 V/0 V or +12 V/0 V rails when biased at mid-supply. Output swings to within 1.5 V of rails (e.g., 0.5 V to 4.5 V on +5 V), confirmed in Table 6 and Figure 16 of the datasheet.
How does the offset null functionality work on the TLE2027IDR?
The TLE2027IDR provides dedicated OFFSET N1 (Pin 1) and OFFSET N2 (Pin 5) terminals for external nulling. A 20 kΩ potentiometer is connected between these pins, with its wiper grounded; adjusting the potentiometer trims input offset voltage to <5 μV. This is documented in the "Pin Assignments" diagram (page 1) and "Offset Nulling" section of TI SLOS192C.
Is the TLE2027IDR pin-compatible with other devices in the TLE20x7 family?
Yes, all TLE20x7 variants - including TLE2027IDR, TLE2027CDR, TLE2027AIDR, and TLE2037IDR - share identical SOIC-8 (D) package pinouts per the "D, JG, OR P PACKAGE (TOP VIEW)" diagram on page 1 of SLOS192C. Pin 1 is OFFSET N1, Pin 2 is IN−, Pin 3 is IN+, Pin 4 is VCC−, Pin 5 is OFFSET N2, Pin 6 is OUT, Pin 7 is VCC+, and Pin 8 is NC - ensuring direct PCB layout reuse across the family.
