Product details
Overview
TLE2141IP from Texas Instruments is a high-speed, low-noise precision operational amplifier built on the Excalibur complementary bipolar process. It delivers 27V/μs slew rate, 5.9MHz gain-bandwidth product, and 10.5nV/√Hz input voltage noise at 1kHz - enabling high-fidelity signal conditioning in industrial power conversion and safety-critical monitoring circuits.
For engineers reviewing the TLE2141IP datasheet, TLE2141IP pinout, TLE2141IP application, or TLE2141IP equivalent, key selection considerations include its ±2V to ±22V dual-supply operation, 150ns saturation recovery, 0.1% settling in 340ns, and guaranteed 500μV max input offset voltage over temperature - critical for precision DC-coupled amplification and fast actuator control loops.
Technical Context
The TLE2141IP integrates a symmetrical input stage optimized for low audio-band noise (10.5nV/√Hz, 10Hz 1/f corner) and robust drive capability into 1000pF loads. Its internal compensation ensures stable unity-gain operation with phase margin ≥57° under 2kΩ//100pF conditions.
It supports comparator mode with TTL-compatible propagation delay (~200ns) and withstands differential inputs up to ±44V without damage. The device operates across −40°C to +105°C (I-suffix), making it suitable for industrial AC-DC and EV charging infrastructure where thermal resilience and rail-to-rail output swing are essential.
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 |
|---|---|---|---|
| OPA211IDR | Lower noise (1.1nV/√Hz), lower supply current (3.6mA), but narrower supply range (±2.25V to ±18V) and no offset null pins | Better suited for battery-powered precision instruments; lacks robustness for industrial ±22V rails | Select when ultra-low noise dominates over rail flexibility and trimming capability |
| AD8675ARZ | Zero-drift architecture, 10μV max VIO, but slower slew rate (2.5V/μs) and lower GBW (10MHz) | Ideal for DC-coupled sensor front-ends requiring long-term stability; unsuitable for fast transient response | Select when offset drift over temperature is more critical than speed or noise performance |
Compared with OPA211IDR and AD8675ARZ, the TLE2141IP uniquely balances high slew rate, wide supply tolerance, and user-adjustable offset - making it optimal for industrial power electronics where both speed and ruggedness are non-negotiable.

FAQ
What is the maximum capacitive load the TLE2141IP can drive without instability?
The TLE2141IP is specified to drive up to 1000pF while maintaining stability and phase margin ≥57°, as verified under 2kΩ//100pF test conditions. This eliminates the need for series isolation resistors in ADC driver or active filter applications, unlike many general-purpose op-amps limited to <100pF.
Does the TLE2141IP support single-supply operation?
Yes, the TLE2141IP operates from a single +4V to +44V supply, with Pin 8 serving as ground reference. Its input common-mode range extends to VCC− − 0.3V, and output swings to within 0.1V of ground - enabling true single-supply signal conditioning in industrial sensor interfaces.
How does the TLE2141IP's offset voltage compare to the TLE2141A variant?
The TLE2141IP has a maximum input offset voltage of 500μV at 25°C, whereas the TLE2141A grade is tighter at 200μV max. Both share identical pinout, package, and dynamic performance - the A-grade is selected when sub-0.2mV DC accuracy is required in high-precision measurement systems.
Can the TLE2141IP be used as a comparator?
Yes, the TLE2141IP is explicitly characterized for comparator use, with typical open-loop propagation delay of 200ns at TTL supply levels. Its differential input tolerance of ±44V and 150ns saturation recovery make it suitable for overvoltage/overcurrent protection circuits where dedicated comparators lack integrated hysteresis or drive strength.
What is the thermal performance of the TLE2141IP in PDIP package?
The TLE2141IP in 8-pin PDIP has a junction-to-ambient thermal resistance (θJA) of 84.6°C/W. At 4.5mA supply current and ±15V operation, typical power dissipation is ~135mW - resulting in ~11.4°C junction rise above ambient, well within safe limits for continuous operation at 105°C ambient.
