Product details
Overview
TLE2141AID from Texas Instruments is a precision bipolar operational amplifier optimized for high-speed, low-noise signal conditioning in industrial and power electronics systems. It delivers 5.9MHz gain-bandwidth, 27V/μs slew rate (±15V supply), 10.5nV/√Hz input voltage noise at 1kHz, ±22V supply range, and 500μV max input offset voltage at 25°C - enabling accurate amplification in EV charging infrastructure and fire alarm control panels.
For engineers reviewing the TLE2141AID datasheet, TLE2141AID pinout, TLE2141AID application, or TLE2141AID equivalent, this page provides verified package mapping (SOIC-8), confirmed pin functions, real-world settling time (340ns to 0.1%), saturation recovery (150ns), and validated alternatives for precision analog signal chains requiring rail-to-rail output swing and robust load drive (1000pF).
Technical Context
The TLE2141AID uses TI's Excalibur complementary bipolar process to achieve simultaneous low audio-band noise (10.5nV/√Hz, 10Hz 1/f corner) and symmetrical 27V/μs slew rate under ±15V operation with up to 800pF capacitive loads. Its input stage supports differential inputs across full supply rails without damage.
It operates as both precision op amp and comparator, with TTL-level open-loop propagation delay of ~200ns and fast saturation recovery (150ns), making it suitable for closed-loop actuator drivers and overvoltage detection circuits where timing integrity and output swing (VCC− + 0.1V to VCC+ − 1V) are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 5.9MHz - enables stable unity-gain operation up to ~6MHz with 100pF load, supporting wideband sensor signal conditioning. |
| Slew rate (±15V) | 27V/μs minimum - ensures faithful reproduction of fast transients in motor current sensing and DC-DC feedback loops. |
| Input offset voltage | 500μV maximum at 25°C - reduces DC error in precision instrumentation amplifiers and battery voltage monitors. |
| Input voltage noise | 10.5nV/√Hz at 1kHz - minimizes audible-band distortion in audio preamps and low-level signal amplification stages. |
| Supply voltage range | ±2V to ±22V (or 4V to 44V single supply) - supports direct integration into industrial AC-DC power supplies and string inverters. |
| Settling time | 340ns to 0.1% on 10V step - meets timing requirements for high-speed data acquisition and fast-positioning control systems. |
| Output swing | VCC− + 0.1V to VCC+ − 1V - maximizes dynamic range in single-supply configurations while maintaining headroom for load stability. |
Pinout & Package
Package: SOIC-8 (D package), 4.9mm × 6mm body size, surface-mount, industry-standard footprint compatible with automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Offset Null (N1) | Connects to external 5kΩ potentiometer wiper for manual input offset trimming; improves DC accuracy in precision measurement paths. |
| 2 | Inverting Input (IN−) | Differential input node; accepts feedback signals in standard inverting amplifier configurations and active filter topologies. |
| 3 | Non-inverting Input (IN+) | Differential input node; used for reference-based sensing, summing junctions, and comparator hysteresis networks. |
| 4 | VCC− (Negative Supply) | Ground reference for split-supply operation; supports −22V absolute maximum rating and common-mode input down to VCC−. |
| 5 | Offset Null (N2) | Connects to potentiometer ends for balanced null adjustment; required only when ultra-low offset drift is needed. |

| 7 | VCC+ (Positive Supply) | Power rail for split or single supply; supports up to +22V absolute maximum and enables rail-swing output to within 1V of VCC+. |
| 8 | NC | No internal connection - left unconnected per TI datasheet; not used for thermal or electrical performance. |
Key Features
| Feature | Design Value |
|---|---|
| Low 1/f noise corner | 10Hz - preserves signal fidelity in DC-coupled sensor interfaces and low-frequency precision measurement systems. |
| Fast saturation recovery | 150ns - enables reliable use in comparator mode for overcurrent protection and fault-detection circuits without latch-up delays. |

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 (1.1nV/√Hz), lower VIO (25μV), but 4.5mA supply current vs. 4.4mA; SOIC-8, same pinout. | Better for ultra-low-noise audio or medical instrumentation; less suited for high-output-swing industrial loads due to lower output current. | Select OPA211AIDR when sub-200μV offset and <2nV/√Hz noise dominate; retain TLE2141AID for ruggedized 20mA drive and ±22V operation. |
| AD8675ARZ | Zero-drift architecture, 10μV VIO, 2.8nV/√Hz noise, but limited to ±15V max supply and 10mA output current. | Ideal for DC-critical applications like precision DAC buffers; lacks TLE2141AID's 1000pF load drive and extended voltage range. | Choose AD8675ARZ for zero-drift stability in lab equipment; prefer TLE2141AID for industrial environments demanding wide supply and robust output. |
Compared with OPA211AIDR and AD8675ARZ, the TLE2141AID uniquely balances high-speed precision (27V/μs, 5.9MHz) with industrial-grade supply range (±22V), output drive (20mA), and capacitive load tolerance (1000pF), making it optimal for power electronics signal chains where reliability under stress matters more than ultra-low offset.

FAQ
What is the maximum capacitive load the TLE2141AID can drive without compensation?
The TLE2141AID is specified to drive up to 1000pF capacitive loads stably without external compensation, as confirmed in the datasheet's "Load capability" feature and operating characteristics tables. This capability eliminates series isolation resistors in ADC driver and cable-driving applications, preserving signal integrity and reducing component count in industrial I/O modules.
Does the TLE2141AID support single-supply operation, and what is its minimum recommended supply voltage?
Yes, the TLE2141AID supports true single-supply operation from 4V to 44V, with recommended minimum of ±2V (i.e., 4V total) in split configuration or 4V in single-ended mode. Its input common-mode range extends to VCC− − 0.3V, and output swings to within 0.1V of VCC− and 1V of VCC+, enabling effective use in 5V or 12V industrial control systems.
How does the TLE2141AID's input offset voltage compare to the standard TLE2141ID, and why does it matter?
The TLE2141AID has a maximum input offset voltage of 500μV at 25°C, versus 1000μV for the TLE2141ID - a tighter grade denoted by the "A" suffix. This 2× improvement reduces DC error in precision gain stages, such as current-sense amplifiers in EV chargers, where even 200μV offset translates to measurable measurement inaccuracy at low shunt voltages.
Can the TLE2141AID be used as a comparator, and what is its typical propagation delay?
Yes, the TLE2141AID is explicitly characterized for comparator use, with typical open-loop propagation delay of 200ns under TTL supply levels. Its fast saturation recovery (150ns) and rail-to-rail input capability allow reliable overvoltage/overcurrent detection in power converters without external hysteresis components - though dedicated comparators offer faster response.
What is the thermal resistance (θJA) of the TLE2141AID in its SOIC-8 package, and how does it affect power dissipation?
The TLE2141AID in SOIC-8 (D package) has a junction-to-ambient thermal resistance (θJA) of 97.1°C/W, as specified in Absolute Maximum Ratings. At its typical 4.4mA supply current and ±15V operation (132mW dissipation), this yields ~12.8°C junction-to-ambient rise - well within safe limits for operation up to 105°C ambient, provided PCB copper area meets JEDEC standards.
