Product details
Overview
TLE2142IDR from Texas Instruments is a dual-channel, high-speed precision operational amplifier optimized for low-noise, wide-supply, and fast-settling applications. It delivers 27V/μs slew rate, 5.9MHz gain-bandwidth product, 10.5nV/√Hz input voltage noise at 1kHz, ±2V to ±22V supply range, and 500μV max input offset voltage at 25°C - enabling high-fidelity signal conditioning in industrial power electronics.
For engineers reviewing the TLE2142IDR datasheet, TLE2142IDR pinout, TLE2142IDR application, or TLE2142IDR equivalent, key selection considerations include its Excalibur bipolar process for symmetrical slew rate, 1000pF capacitive load drive capability, 400ns 0.01% settling time (±15V), and SOIC-8 packaging suitable for EV charging infrastructure and string inverter feedback loops.
Technical Context
The TLE2142IDR uses TI's complementary bipolar Excalibur process to achieve simultaneous low audio-band noise (10.5nV/√Hz @1kHz, 10Hz 1/f corner) and symmetrical 40V/μs typical slew rate with up to 800pF load stability. Its input stage supports rail-to-rail common-mode range (VCC− to VCC+ −0.3V) and differential inputs up to ±44V without damage.
It operates as both precision op amp and comparator: open-loop propagation delay is ~200ns at TTL levels, and saturation recovery is specified at 150ns. The device maintains stable unity-gain performance with 57° phase margin (RL = 2kΩ, CL = 100pF) and supports single (4–44V) or split (±2–±22V) supplies.
Key Specifications

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 VIO (25μV), but only ±18V max supply and 45MHz GBW - requires higher quiescent current (3.6mA/ch). | Better for ultra-low-noise audio or metrology; less suitable for >±20V industrial rails or high-capacitive-load buffering. | Choose OPA211AIDR when sub-10nV/√Hz noise and microvolt offset dominate; verify supply compliance and layout stability. |
| LT1013DIDR | Higher VIO (250μV typ), slower slew (0.4V/μs), but superior CMRR (120dB) and lower cost; rated for −55°C to +125°C (M-grade). | Preferred for legacy military/aerospace designs where long-term drift and extreme temperature stability outweigh speed. | Choose LT1013DIDR for cost-sensitive, low-bandwidth, high-reliability applications where 27V/μs slew is unnecessary. |
Compared with OPA211AIDR and LT1013DIDR, the TLE2142IDR uniquely balances high slew rate, wide supply range, and low 1/f noise - making it optimal for industrial power conversion where both speed and precision under harsh voltage conditions are required.

FAQ
What is the maximum capacitive load the TLE2142IDR can drive stably?
The TLE2142IDR is characterized to drive up to 1000pF capacitive load without oscillation or excessive overshoot, per TI datasheet Section 1. This capability enables direct interfacing with ADC input capacitors, long PCB traces, or RC filtering networks without requiring isolation resistors - a key advantage over many general-purpose op amps limited to <100pF.
Does the TLE2142IDR support single-supply operation?
Yes, the TLE2142IDR supports single-supply operation from 4V to 44V. Its input common-mode range extends to VCC− (typically GND in single-supply mode), and output swings to within 0.1V of VCC− and 1V of VCC+, enabling true ground-sensing and rail-to-rail output utilization in systems like battery monitors and sensor interfaces.
What is the operating temperature range for the TLE2142IDR?
The TLE2142IDR is an I-suffix device rated for −40°C to +105°C operating free-air temperature. This industrial-grade range is validated per TI's characterization and testing protocols, making it suitable for deployment in enclosed power cabinets, outdoor EV chargers, and factory automation equipment without derating.
Can the TLE2142IDR be used as a comparator?
Yes, the TLE2142IDR can operate as a comparator: its differential inputs tolerate VCC± without damage, and open-loop propagation delay is typically 200ns at TTL supply levels. Saturation recovery is specified at 150ns, allowing reliable use in overvoltage latch circuits and fast fault-detection paths - though dedicated comparators offer faster response.
How does the TLE2142IDR's noise performance compare between 10Hz and 1kHz?
The TLE2142IDR exhibits 15nV/√Hz input voltage noise at 10Hz and 10.5nV/√Hz at 1kHz, confirming a low 1/f corner near 10Hz. This behavior - verified in TI's SLOS183E datasheet Section 5.4 - ensures minimal low-frequency drift in DC-coupled applications such as strain gauge amplifiers and thermocouple signal chains.
