Product details
Overview
TLE2141CDR from Texas Instruments is a single-channel Excalibur low-noise high-speed precision operational amplifier designed for demanding signal conditioning in industrial power electronics. It delivers 27V/μs minimum slew rate, 5.9MHz gain-bandwidth product, 10.5nV/√Hz input voltage noise at 1kHz, ±22V supply range, and 500μV maximum input offset voltage at 25°C - enabling high-fidelity current sensing and fast actuator control in EV charging infrastructure.
For engineers reviewing the TLE2141CDR datasheet, TLE2141CDR pinout, TLE2141CDR application, or TLE2141CDR equivalent, key selection criteria include its 10000pF capacitive load drive capability, 340ns settling time to 0.1%, symmetrical slew rate, rail-to-rail output swing (VCC− + 0.1V to VCC+ − 1V), and operation across 0°C to 70°C ambient temperature.
Technical Context
The TLE2141CDR uses TI's complementary bipolar Excalibur process to achieve simultaneous low audio-band noise (10.5nV/√Hz at 1kHz, 10Hz 1/f corner) and high slew rate (27V/μs min). Its input stage supports differential inputs up to ±44V without damage and enables comparator use with 200ns typical open-loop propagation delay under TTL supply levels.
It features internal compensation, fast saturation recovery (150ns), and stable operation driving heavy capacitive loads up to 10000pF. The device maintains specified performance across ±2V to ±22V split supplies or 4V to 44V single supply, with common-mode input range extending to within 0.3V of either rail.

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA211IDR | Lower noise (1.1nV/√Hz), lower supply current (3.6mA), but narrower supply range (±18V max) and no offset null pins | Better suited for battery-powered precision instruments; lacks robustness for 44V industrial rails | Select when ultra-low noise dominates over supply flexibility and trimming capability |
| AD8675ARZ | Higher precision (10μV VIO), lower drift (0.6μV/°C), but slower slew rate (2.5V/μs) and lower GBW (10MHz) | Ideal for DC-coupled metrology; insufficient speed for fast transient response in power control | Select for sub-ppm DC accuracy where bandwidth <1MHz is acceptable |
Compared with OPA211IDR and AD8675ARZ, the TLE2141CDR uniquely balances high slew rate, wide supply range, and offset trim capability - making it optimal for industrial power electronics requiring both speed and DC precision under harsh voltage conditions.

FAQ
What is the maximum capacitive load the TLE2141CDR can drive stably?
The TLE2141CDR is characterized to drive up to 10000pF capacitively without oscillation or phase reversal, verified across ±15V supply and 25°C ambient. This capability eliminates need for series isolation resistors when interfacing with ADC input filters or long PCB traces in industrial control systems. Stability is maintained due to internal compensation optimized for heavy capacitive loading.
Does the TLE2141CDR support single-supply operation?
Yes, the TLE2141CDR operates from a single 4V to 44V supply. Its input common-mode range extends to VCC− (ground) and output swings to within 0.1V of VCC− and 1V of VCC+, enabling true single-supply signal conditioning in 24V or 48V industrial systems. Input bias current remains stable across this full range, ensuring predictable performance in rail-to-rail configurations.
How does the TLE2141CDR's offset null functionality work?
The TLE2141CDR provides dedicated OFFSET N1 (Pin 1) and OFFSET N2 (Pin 5) terminals for external trimming of input offset voltage using a 10kΩ potentiometer. This allows reduction of initial VIO from 500μV max to <50μV in production calibration - critical for high-accuracy current shunt amplifiers where offset directly impacts measurement error at low currents.
What is the thermal performance of the TLE2141CDR in SOIC-8 package?
In the D-package (SOIC-8), the TLE2141CDR has a junction-to-ambient thermal resistance (θJA) of 97.1°C/W. At 4.5mA quiescent current and ±15V supply, typical power dissipation is ~135mW, resulting in ~13°C junction rise above ambient - well within safe limits for continuous operation at 70°C ambient. No heatsink is required for standard industrial mounting.
Can the TLE2141CDR be used as a comparator?
Yes, the TLE2141CDR is explicitly characterized for comparator use, with 200ns typical open-loop propagation delay at TTL logic levels and differential input tolerance up to ±44V. Its fast saturation recovery (150ns) and rail-to-rail output make it suitable for overvoltage detection and fast threshold comparison in power supply supervision circuits - though dedicated comparators offer faster response for timing-critical applications.
