Product details
Overview
TLE2141MD from Texas Instruments is a military-grade Excalibur bipolar operational amplifier optimized for precision, low-noise, high-speed signal conditioning in harsh environments. It delivers 5.9MHz gain-bandwidth, 27V/μs slew rate (±15V), 10.5nV/√Hz input noise at 1kHz, ±2V to ±22V supply range, and operates across −55°C to +125°C. It serves as a pin-compatible upgrade in EV charging infrastructure and industrial AC-DC power control loops.
For engineers reviewing the TLE2141MD datasheet, TLE2141MD pinout, TLE2141MD application, or TLE2141MD equivalent, key selection criteria include its guaranteed 20mA short-circuit output current, 340ns settling time to 0.1%, saturation recovery of 150ns, rail-to-rail input stage tolerance (VCC±), and military-temperature validated offset voltage ≤500μV at 25°C.
Technical Context
The TLE2141MD uses TI's complementary bipolar Excalibur process to achieve simultaneous low audio-band noise (10.5nV/√Hz, 10Hz 1/f corner) and symmetrical 27V/μs slew rate into ≥800pF loads. Its input stage withstands differential inputs up to ±44V without damage, enabling robust operation in noisy industrial sensor front-ends.
It supports both single-supply (4V–44V) and split-supply (±2V–±22V) configurations, with common-mode input range extending to VCC− −0.3V and output swing from VCC− + 0.1V to VCC+ − 1V. Open-loop propagation delay is 200ns under TTL logic levels, confirming fast comparator-mode response.

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA277MD | Lower noise (8nV/√Hz), lower GBW (1MHz), no offset null pins, SOIC-8 package only. | Better for ultra-low-noise DC applications; unsuitable for high-speed settling or adjustable nulling. | Select OPA277MD when offset trim is unnecessary and bandwidth <1.5MHz suffices. |
| LM148J | Higher VIO (2mV max), slower slew (0.5V/μs), wider temp range (−55°C to +125°C), same JG-8 package. | Legacy military quad op-amp; acceptable where speed/noise specs are relaxed. | Choose LM148J only for cost-sensitive legacy redesigns with no performance upgrade path. |
Compared with OPA277MD and LM148J, the TLE2141MD uniquely balances high-speed precision (27V/μs, 5.9MHz) with field-serviceable offset trimming and military-grade ruggedness-making it irreplaceable in next-generation EV and renewable energy power electronics requiring both speed and long-term calibration stability.

FAQ
What is the maximum operating supply voltage for the TLE2141MD?
The TLE2141MD supports a maximum supply voltage of ±22V (or 44V total across VCC+ and VCC−). This is specified in the Absolute Maximum Ratings table, and operation beyond this risks permanent damage. For reliable long-term use, TI recommends staying within ±22V under all conditions including transients.
Does the TLE2141MD support single-supply operation?
Yes, the TLE2141MD supports true single-supply operation from 4V to 44V. Its input common-mode range extends to VCC− − 0.3V, and output can swing to within 0.1V of VCC−, enabling direct interfacing with microcontrollers and ADCs referenced to ground. The device remains fully functional with VCC− tied to GND.
Can the TLE2141MD be used as a comparator?
Yes, the TLE2141MD can be used as a comparator. TI explicitly states both TLE214x and TLE214xA versions function as comparators, with typical open-loop propagation delay of 200ns at TTL supply levels. However, it lacks built-in hysteresis or latch functionality, so external positive feedback is required for noise immunity in real-world applications.
What is the purpose of Pins 1 and 5 on the TLE2141MD?
Pins 1 and 5 are dedicated offset null terminals for the TLE2141MD. Pin 1 (N1) connects to the wiper of an external 5kΩ potentiometer; Pin 5 (N2) connects to one end of that pot and a 1kΩ resistor to VCC−. This configuration allows manual trimming of input offset voltage to <50μV, critical for high-accuracy DC measurements where auto-zeroing is unavailable.
How does the TLE2141MD's noise performance compare between 10Hz and 1kHz?
The TLE2141MD exhibits 15nV/√Hz input voltage noise at 10Hz and 10.5nV/√Hz at 1kHz. This confirms a low 1/f noise corner at 10Hz, meaning low-frequency drift and flicker noise are minimized-ideal for applications like precision weigh scales or slow-servo position feedback where sub-Hz bandwidth dominates error sources.
