Product details
Overview
TLE2142AID from Texas Instruments is a dual-channel, high-speed precision operational amplifier with Excalibur bipolar process technology. It delivers 5.9MHz gain-bandwidth, 27V/μs slew rate, and low input offset voltage (≤500μV at 25°C), enabling accurate signal conditioning in industrial power conversion and safety-critical monitoring circuits.
For engineers reviewing the TLE2142AID datasheet, TLE2142AID pinout, TLE2142AID application, or TLE2142AID equivalent, key selection criteria include its ±2V to ±22V supply range, 10.5nV/√Hz input noise at 1kHz, fast 430ns settling to 0.1%, and SOIC-8 package compatibility with legacy TI op-amp footprints.
Technical Context
The TLE2142AID integrates a symmetrical input stage optimized for low audio-band noise (10.5nV/√Hz) and 10Hz 1/f corner, paired with a robust output stage capable of driving ≥1000pF loads while maintaining stability. Its internal compensation ensures unity-gain stability without external components.
It supports single-supply (4V–44V) or split-supply (±2V–±22V) operation, features rail-to-rail input common-mode range down to VCC− −0.3V, and exhibits fast saturation recovery (150ns), making it suitable for comparator use in overvoltage detection and fast feedback loops.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 5.9MHz - enables stable closed-loop operation up to ~500kHz with moderate gain (e.g., AV = 10). |
| Slew rate | 27V/μs (min) - supports clean amplification of fast transients up to ~10V step in ≤370ns. |
| Input offset voltage | ≤500μV at 25°C - reduces DC error in precision sensor interfaces and current-sense amplifiers. |
| Input voltage noise | 10.5nV/√Hz at 1kHz - preserves SNR in low-level analog front-ends like fire alarm signal chains. |
| Supply voltage range | ±2V to ±22V (split) or 4V to 44V (single) - accommodates wide industrial bus voltages including 24VDC and 48VDC systems. |
| Output swing | VCC− + 0.1V to VCC+ − 1V - delivers >22VPP output with ±15V supplies, critical for actuator drivers in EV charging control. |
| Settling time | 430ns to 0.1% (10V step) - meets timing requirements in fast-positioning feedback paths and string inverter voltage regulation. |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Offset Null (N1) | Connects to 1kΩ potentiometer wiper for manual input offset trimming; required only in ultra-precision applications. |
| 2 | Inverting Input (IN−) | Differential input node; accepts signals referenced to ground or virtual ground in inverting configurations. |
| 3 | Non-inverting Input (IN+) | Differential input node; used in non-inverting amplifiers, comparators, and reference buffers. |
| 4 | VCC− (Negative Supply) | Ground or negative rail connection; supports single- or dual-supply operation. |
| 5 | Offset Null (N2) | Connects to 5kΩ potentiometer end for manual offset nulling circuit; unused if trimming not required. |
| 6 | Output (OUT) | Amplified output; drives resistive or capacitive loads up to 1000pF without instability. |
| 7 | VCC+ (Positive Supply) | Positive supply rail; must be decoupled locally with 0.1μF ceramic capacitor. |
| 8 | NC | No connect - internal die pad; left unconnected per TI design guidelines. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA211AIDR | Lower noise (1.1nV/√Hz), lower supply current (3.6mA), but narrower supply range (±2.25V to ±18V). | Better for ultra-low-noise audio or instrumentation; less suitable for 48V industrial rails. | Select when noise dominates performance budget and supply voltage stays ≤±18V. |
| LM7332MAX/NOPB | Higher slew rate (45V/μs), rail-to-rail output, but higher offset (1.8mV max) and no offset-null pins. | Preferred for high-speed, rail-to-rail output needs where DC precision is secondary. | Choose when driving ADC inputs directly or requiring full output swing near rails. |
Compared with OPA211AIDR and LM7332MAX/NOPB, the TLE2142AID uniquely balances low noise, high supply voltage tolerance, and manual offset trimming-making it optimal for industrial power monitoring where both accuracy and ruggedness are required.

FAQ
What is the maximum operating temperature range for the TLE2142AID?
The TLE2142AID is characterized for operation from −40°C to +105°C (I-suffix grade), making it suitable for industrial environments such as EV charging stations and solar string inverters where ambient temperatures exceed standard commercial limits. This range is confirmed in the device's Recommended Operating Conditions table and applies across its full specified supply and load conditions.
Does the TLE2142AID support single-supply operation?
Yes, the TLE2142AID supports single-supply operation from 4V to 44V. Its input common-mode range extends to VCC− −0.3V, allowing use with ground-referenced inputs, and its output swings to within 1V of VCC+, enabling effective signal amplification in 5V, 12V, 24V, and 48V systems without level-shifting circuitry.
Can the TLE2142AID be used as a comparator?
Yes, the TLE2142AID can be used as a comparator due to its fast saturation recovery (150ns) and ability to withstand differential input voltages up to ±44V without damage. However, it lacks dedicated comparator features like open-collector output or internal hysteresis, so external hysteresis must be added for noise immunity in noisy industrial settings.
What is the purpose of Pins 1 and 5 on the TLE2142AID?
Pins 1 and 5 are offset null terminals for manual trimming of input offset voltage using an external potentiometer (typically 1kΩ wiper to Pin 1, 5kΩ ends to Pins 1 and 5). This feature allows reduction of initial VIO below the 500μV maximum spec-critical in high-accuracy current sensing or precision reference buffering applications using the TLE2142AID.
How does the TLE2142AID compare to the standard TLE2142 in terms of offset voltage?
The TLE2142AID is the tighter offset voltage grade of the TLE2142 family, with a maximum input offset voltage of 500μV at 25°C versus 1200μV for the base TLE2142C grade. This 2.4× improvement directly enhances DC accuracy in applications like battery voltage monitoring and isolation amplifier feedback networks where offset drift contributes significantly to system error.
