Product details
Overview
TLE2141AIDR from Texas Instruments is a high-speed, low-noise precision operational amplifier in SOIC-8 package, featuring 10.5nV/√Hz input voltage noise at 1kHz, 27V/μs minimum slew rate, 5.9MHz gain-bandwidth product, ±2V to ±22V dual-supply operation, and 500μV maximum input offset voltage at 25°C - deployed in EV charging infrastructure signal conditioning and industrial AC-DC feedback loops.
For engineers reviewing the TLE2141AIDR datasheet, TLE2141AIDR pinout, TLE2141AIDR application, or TLE2141AIDR equivalent, this page delivers verified specifications, package mapping, functional alternatives, and design-critical settling time (340ns to 0.1%), saturation recovery (150ns), and load drive capability (10000pF) for high-fidelity analog signal paths.
Technical Context
The TLE2141AIDR uses TI's Excalibur complementary bipolar process to achieve simultaneous low audio-band noise (10.5nV/√Hz, 10Hz 1/f corner) and symmetrical 40V/μs typical slew rate with up to 800pF capacitive loads. Its input stage enables high-fidelity audio and fast actuator positioning without stability compromise.
It supports comparator operation with differential inputs rated to VCC±, TTL-level open-loop propagation delay of 200ns, and robust saturation recovery (150ns). The device maintains rail-to-rail input common-mode range (e.g., –15V to +12.9V at ±15V supply) and large output swing (VCC− + 0.1V to VCC+ − 1V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 5.9MHz - ensures stable unity-gain operation with ≥57° phase margin into 2kΩ//100pF loads. |
| Slew rate (min) | 27V/μs - enables accurate reproduction of fast transients in motor control and power supply feedback. |
| Input voltage noise | 10.5nV/√Hz at 1kHz - critical for low-distortion signal amplification in sensor front-ends and audio paths. |
| Input offset voltage (max) | 500μV at 25°C - supports precision DC-coupled applications like current sensing and instrumentation amplifiers. |
| Supply voltage range | ±2V to ±22V - accommodates wide industrial and automotive supply rails without external regulation. |
| Settling time | 340ns to 0.1% on 10V step - meets timing requirements in high-speed data acquisition and closed-loop position control. |
| Output load drive | 10000pF - allows direct driving of long cables or ADC input capacitance without external buffering. |

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 (3.8nV/√Hz), lower VIO (25μV), but 4.5MHz GBW and 10V/μs slew rate - not drop-in. | Better for ultra-low-noise sensor interfaces; insufficient speed for fast-settling power control loops. | Select OPA211AIDR only when noise dominates over speed; verify loop stability with reduced GBW. |
| LM7332MA/NOPB | Higher slew rate (32V/μs), wider supply (±16V), but higher noise (16nV/√Hz) and 2mV VIO - different pinout. | Suitable for high-speed industrial I/O, but lacks TLE2141AIDR's low-noise precision for measurement-grade designs. | Choose LM7332MA/NOPB for cost-sensitive, speed-critical applications where 10.5nV/√Hz noise is non-critical. |
Compared with OPA211AIDR and LM7332MA/NOPB, the TLE2141AIDR uniquely balances 10.5nV/√Hz noise, 27V/μs slew rate, and 5.9MHz GBW in an SOIC-8 package - making it optimal for industrial power conversion where both fidelity and transient response are essential.

FAQ
What is the maximum capacitive load the TLE2141AIDR can drive without instability?
The TLE2141AIDR is characterized to drive up to 10000pF while maintaining stability and specified performance, as confirmed in the TI datasheet SLOS183E Section 1. This capability eliminates the need for external isolation resistors when interfacing with ADCs or long PCB traces, simplifying layout and improving signal integrity in power electronics applications using the TLE2141AIDR.
Does the TLE2141AIDR support single-supply operation?
Yes, the TLE2141AIDR operates from a total supply range of 4V to 44V, enabling true single-supply use (e.g., VCC+ = 36V, VCC− = GND). Its input common-mode range extends to VCC−, and output swings to within 0.1V of VCC−, making it suitable for ground-referenced sensor interfaces and industrial I/O without level-shifting circuitry - a key advantage of the TLE2141AIDR in cost-constrained designs.
What is the guaranteed input offset voltage specification for the TLE2141AIDR?
The TLE2141AIDR guarantees a maximum input offset voltage of 500μV at 25°C, per TI datasheet SLOS183E Section 5.5. This tighter VIO grade (vs. standard TLE2141) enables high-accuracy DC measurements in current-sense amplifiers and precision instrumentation, especially when combined with its 1.7μV/°C temperature coefficient - a defining specification for the TLE2141AIDR in thermally varying environments.
Can the TLE2141AIDR be used as a comparator?
Yes, the TLE2141AIDR is explicitly qualified for comparator use in the datasheet, with differential input ratings up to ±44V and typical open-loop propagation delay of 200ns at TTL levels. Its fast saturation recovery (150ns) and rail-to-rail input capability make it viable for non-critical comparator functions - though dedicated comparators remain preferred for timing-critical applications involving the TLE2141AIDR.
What is the thermal resistance (θJA) of the TLE2141AIDR in its SOIC-8 package?
The TLE2141AIDR in SOIC-8 (D package) has a junction-to-ambient thermal resistance (θJA) of 97.1°C/W, as specified in TI datasheet SLOS183E Section 5.1. This value informs thermal design for continuous operation at elevated ambient temperatures - particularly important in enclosed EV charging modules or industrial power supplies where the TLE2141AIDR may operate near its 125°C max junction limit.
