Product details
Overview
TLE2141ID from Texas Instruments is a high-speed precision operational amplifier with low-noise performance (10.5nV/√Hz at 1kHz), 27V/μs minimum slew rate, and 5.9MHz gain-bandwidth product, designed for signal conditioning in industrial power electronics such as EV charging infrastructure and string inverters.
For engineers reviewing the TLE2141ID datasheet, TLE2141ID pinout, TLE2141ID application, or TLE2141ID equivalent, key selection criteria include input offset voltage (≤500μV at 25°C), wide supply range (±2V to ±22V), fast settling time (400ns to 0.01%), and robust output drive capability into 10000pF loads.
Technical Context
The TLE2141ID uses TI's Excalibur complementary bipolar process to achieve simultaneous low audio-band noise (10.5nV/√Hz) and symmetrical slew rate (27V/μs min). Its input stage supports differential inputs up to ±44V without damage and enables comparator operation with TTL-level propagation delay (~200ns).
It features internal compensation, rail-to-rail input common-mode range (−15V to +12.9V at ±15V supplies), and saturation recovery in 150ns. Output swing extends to VCC− + 0.1V and VCC+ − 1V under load, supporting high-fidelity analog signal paths in demanding industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 5.9MHz - ensures stable unity-gain operation with phase margin ≥57° and usable bandwidth up to 668kHz at 2VPP output swing. |
| Slew rate | 27V/μs (min) - enables accurate reproduction of fast transients in motor control feedback or current-sense amplification. |
| Input offset voltage | 500μV max at 25°C - minimizes DC error in precision sensor interfaces and closed-loop regulation circuits. |
| Supply voltage range | ±2V to ±22V - supports single-supply (4V–44V) or split-supply operation across diverse industrial power rails. |
| Settling time | 400ns to 0.01% - critical for high-speed actuator positioning and fast ADC driver applications. |
| Output load capability | 10000pF - allows direct driving of long traces, capacitive sensors, or MOSFET gates without external buffering. |
| Input noise voltage | 10.5nV/√Hz at 1kHz - preserves SNR in low-level signal amplification such as thermocouple or strain gauge front-ends. |
Pinout & Package
Package: SOIC-8 (D package), 4.9mm × 6mm body size, surface-mount, industry-standard footprint compatible with automated assembly.

| 4 | VCC− | Negative supply terminal; rated for −22V absolute maximum, supports split or dual supply configurations. |
| 5 | Offset Null (N2) | Connects to one end of 5kΩ potentiometer and 1kΩ resistor to ground for offset trimming. |
| 6 | Output (OUT) | Capable of sourcing/sinking ±15mA; swings to within 1V of VCC+ and 0.1V of VCC− under load. |
| 7 | VCC+ | Positive supply terminal; rated for +22V absolute maximum; powers internal bias and output stage. |
| 8 | NC | No connect - internally unused; must remain unconnected per datasheet specification. |
Key Features
| Feature | Design Value |
|---|---|
| Low 1/f noise corner | 10Hz - reduces low-frequency drift in precision instrumentation and DC-coupled measurement systems. |
| Short-circuit output current | 20mA minimum - provides fault tolerance during transient overloads in motor driver or protection circuitry. |
| Saturation recovery time | 150ns - enables rapid return from clipping in high-speed comparators or pulse-width modulation circuits. |
| Large output voltage swing | VCC− + 0.1V to VCC+ − 1V - maximizes dynamic range in single-supply data acquisition and signal reconstruction. |
| Wide temperature range | −40°C to +105°C - qualified for industrial-grade operation in EV charging stations and solar inverters. |

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 IQ (3.6mA), but narrower supply range (±2.25V to ±18V) and no offset null pins. | Better suited for ultra-low-noise, low-power instrumentation; not ideal for high-voltage industrial feedback loops requiring trimming. | Select OPA211IDR when noise dominates design constraints and offset adjustment is unnecessary. |
| AD8610ARZ | Faster slew rate (25V/μs typical), lower VIO (120μV max), but limited output drive (10mA) and no 10000pF load rating. | Preferred for high-precision DAC buffers and medical instrumentation; insufficient for capacitive gate driving or long-line transmission. | Choose AD8610ARZ for sub-200μV offset-critical applications where load capacitance remains below 1000pF. |
Compared with OPA211IDR and AD8610ARZ, the TLE2141ID uniquely balances high-voltage operation (±22V), robust capacitive drive (10000pF), and factory-trimmable offset-making it optimal for industrial power electronics where reliability under stress and field calibration matter.

FAQ
What is the maximum supply voltage rating for the TLE2141ID?
The TLE2141ID has an absolute maximum supply voltage rating of ±22V, meaning VCC+ may reach +22V and VCC− may reach −22V relative to ground. Operation beyond these limits risks permanent device damage. Recommended operating range is ±2V to ±22V, supporting both single-supply (4V–44V) and split-supply configurations in industrial power systems.
Does the TLE2141ID support rail-to-rail input operation?
The TLE2141ID supports rail-to-rail input common-mode voltage operation down to VCC− − 0.3V and up to VCC+ − 1.1V at ±15V supplies (i.e., −15V to +13.9V). This enables direct interfacing with sensors and ADCs referenced to system rails without level-shifting circuitry, improving accuracy and reducing component count in industrial analog front-ends.
Can the TLE2141ID be used as a comparator?
Yes, the TLE2141ID can function as a comparator due to its fast open-loop propagation delay (~200ns at TTL levels) and ability to withstand differential inputs up to ±44V without damage. However, it lacks built-in hysteresis or latch functionality, so external positive feedback or post-amplification may be needed for clean digital output transitions in noisy environments.
What is the purpose of Pins 1 and 5 on the TLE2141ID?
Pins 1 and 5 on the TLE2141ID are offset null terminals used to minimize input offset voltage via an external 5kΩ potentiometer connected between them, with its wiper tied to Pin 1 and one end grounded through a 1kΩ resistor. This trimming capability is essential for high-accuracy applications like precision current sensing and closed-loop regulation where initial VIO drift must be actively corrected.
How does the TLE2141ID handle capacitive loads?
The TLE2141ID is specifically characterized to drive up to 10000pF directly without oscillation or instability, unlike many general-purpose op-amps that require isolation resistors or compensation networks. This makes it ideal for driving long PCB traces, capacitive touch sensors, or MOSFET gates in industrial power stages-reducing design complexity and improving system reliability.
