Product details
Overview
TLE2141AIP from Texas Instruments is a precision bipolar operational amplifier optimized for low-noise, high-speed signal conditioning in industrial and power electronics systems. It delivers 10.5nV/√Hz input voltage noise at 1kHz, 27V/μs slew rate (±15V supply), 5.9MHz gain-bandwidth product, and ±22V supply range - enabling use in EV charging infrastructure front-end sensing and fire alarm control panel analog signal paths.
For engineers reviewing the TLE2141AIP datasheet, TLE2141AIP pinout, TLE2141AIP application, or TLE2141AIP equivalent, this page provides verified specifications, package mapping to PDIP-8, real-world settling time (430ns to 0.1% on 10V step), saturation recovery (150ns), and validated alternatives for precision op-amp selection in high-reliability analog designs.
Technical Context
The TLE2141AIP uses TI's Excalibur complementary bipolar process to achieve simultaneous low audio-band noise (10.5nV/√Hz) and symmetrical 27V/μs slew rate under ±15V supply with up to 800pF capacitive load. Its input stage supports rail-to-rail common-mode range (–15V to +12.9V) and differential inputs up to ±44V without damage.
It features internal compensation, operates as both amplifier and comparator, and includes offset null pins (OFFSET N1/N2) for fine-tuning. Open-loop propagation delay is 200ns with TTL supply levels, supporting fast saturation recovery critical in overcurrent protection circuits.

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 instrumentation; lacks robustness for 44V industrial rails and fine-trim capability | Select when ultra-low noise dominates over rail flexibility and offset calibration needs |
| LT1012ACN8#PBF | Lower VIO (25μV typ), chopper-stabilized architecture, but slower slew rate (0.35V/μs) and higher cost | Ideal for microvolt-level DC measurements; unsuitable for fast transient response or high-frequency closed-loop control | Select only for pure DC precision applications where speed and capacitive drive are secondary |
Compared with OPA211IDR and LT1012ACN8#PBF, the TLE2141AIP uniquely balances low noise, high slew rate, wide supply range, and offset nulling - making it optimal for industrial power electronics where all four attributes are simultaneously required.

FAQ
What is the maximum capacitive load the TLE2141AIP can drive without instability?
The TLE2141AIP is specified to drive up to 10000pF while maintaining stability, as confirmed in the datasheet Features section. This eliminates the need for series isolation resistors in applications such as driving long traces to ADC inputs or capacitive filters in power supply feedback networks. For loads exceeding 10000pF, external compensation or buffer stages are recommended to preserve phase margin above 57°.
Does the TLE2141AIP support single-supply operation, and what is its minimum recommended supply voltage?
Yes, the TLE2141AIP supports true single-supply operation from 4V to 44V total supply range. When used with single supply, VCC− is connected to GND and VCC+ to the positive rail. The minimum 4V supply enables functionality in low-voltage industrial logic systems, while the 44V maximum accommodates 36V and 48V nominal bus architectures common in EV charging and factory automation.
How does the TLE2141AIP's offset voltage compare to the standard TLE2141, and why does that matter?
The TLE2141AIP has a maximum input offset voltage of 500μV at 25°C, versus 2000μV for the base TLE2141 - a fourfold improvement. This tighter grading directly reduces DC error in precision applications like shunt-based current sensing, where 500μV offset translates to <0.25mV error across a 100mΩ sense resistor, enabling sub-1% measurement accuracy without software calibration.
Can the TLE2141AIP be used as a comparator, and what is its typical propagation delay?
Yes, the TLE2141AIP is explicitly characterized for comparator use in the datasheet. With TTL-compatible supply levels, its open-loop propagation delay is typically 200ns - significantly faster than many general-purpose op-amps used in comparator mode. This makes it suitable for overvoltage lockout and fast fault detection circuits where sub-microsecond response is required.
What is the purpose of Pins 1 and 5 (OFFSET N1 and OFFSET N2) on the TLE2141AIP?
Pins 1 and 5 provide dedicated offset null terminals connected to internal 5kΩ and 1kΩ resistors respectively. A 20kΩ potentiometer between these pins and VCC− allows precise trimming of input offset voltage down to <100μV. This capability is essential in applications like precision weigh scales and medical sensor interfaces where residual DC error must be minimized before digitization.
