Product details
Overview
TLE2141MDG4 from Texas Instruments is a military-grade, low-noise, high-speed precision operational amplifier in an 8-pin SOIC package. It delivers 27V/μs slew rate, 5.9MHz gain-bandwidth product, 10.5nV/√Hz input voltage noise at 1kHz, ±22V supply range, and 500μV max input offset voltage at 25°C - enabling high-fidelity signal conditioning in EV charging infrastructure and industrial AC-DC power systems.
For engineers reviewing the TLE2141MDG4 datasheet, TLE2141MDG4 pinout, TLE2141MDG4 application, or TLE2141MDG4 equivalent, key selection considerations include its Excalibur bipolar process for symmetrical slew rate, fast 340ns settling to 0.1%, 10000pF capacitive load drive capability, and full −55°C to +125°C operation without derating.
Technical Context
The TLE2141MDG4 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 under ±15V supply with up to 800pF load. Its input stage supports differential inputs across full supply rails (±44V), and it operates as both precision op amp and comparator with TTL-compatible 200ns open-loop propagation delay.
Designed for demanding analog signal paths, it features saturation recovery in 150ns, large output swing (VCC− + 0.1V to VCC+ − 1V), and robust short-circuit protection (20mA min output current). The M-suffix grade guarantees performance over the full military temperature range (−55°C to +125°C).

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 (3.5nV/√Hz), lower VIO (25μV), but only rated to 105°C and 36V total supply | Better for lab-grade instrumentation; unsuitable for military-temperature or >±18V systems | Select when ultra-low noise dominates over temperature/supply range requirements |
| AD8610ARZ | FEMTOamp bias current (1pA), rail-to-rail output, but 25MHz GBW and 12V max supply limit | Ideal for high-impedance sensor nodes; cannot replace in high-voltage industrial feedback loops | Choose for pH electrodes or piezoelectric sensors where input loading must be minimized |
Compared with OPA211IDR and AD8610ARZ, the TLE2141MDG4 uniquely combines military-temperature operation, ±22V supply tolerance, and 27V/μs slew rate - making it irreplaceable in high-reliability, high-voltage analog signal chains where environmental robustness is non-negotiable.

FAQ
What is the maximum capacitive load the TLE2141MDG4 can drive without oscillation?
The TLE2141MDG4 is characterized to drive up to 10000pF while maintaining stability, as confirmed in the datasheet's load capability specification. This capability stems from its internal compensation optimized for heavy capacitive loads - essential for interfacing directly with ADC input filters or long PCB traces in industrial measurement systems. For optimal phase margin with 10000pF, use recommended layout practices including local bypass capacitors and minimized trace inductance near the output pin.
Does the TLE2141MDG4 support single-supply operation?
Yes, the TLE2141MDG4 supports single-supply operation from 4V to 44V. When used in single-supply mode, Pin 4 (VCC−) connects to system ground (GND), and Pin 8 serves as the ground reference. The input common-mode range extends to within 0.3V of GND, and the output swings to within 1V of VCC+, enabling effective use in 5V, 12V, 24V, or 40V systems - such as battery-powered FACP modules or auxiliary supplies in string inverters.
How does the TLE2141MDG4's offset voltage compare to the commercial-grade TLE2141CDR?
The TLE2141MDG4 has a maximum input offset voltage of 500μV at 25°C, whereas the commercial-grade TLE2141CDR is specified at 2000μV max. This tighter VIO spec reflects the M-suffix military screening and characterization across −55°C to +125°C, ensuring higher DC accuracy in precision feedback loops. Both share identical pinout and electrical architecture, but the M-grade provides guaranteed performance over the full extended temperature range without derating.
Can the TLE2141MDG4 be used as a comparator?
Yes, the TLE2141MDG4 can operate as a comparator, with typical open-loop propagation delay of 200ns under TTL supply conditions. Its differential input withstands ±44V, and output saturates rapidly with 150ns recovery from deep saturation - making it suitable for overvoltage latch circuits or fast threshold detection in EVSE safety monitors. However, dedicated comparators offer faster response and built-in hysteresis; use TLE2141MDG4 as comparator only when precision amplification and comparison share the same signal path.
What is the thermal resistance (θJA) of the TLE2141MDG4 in its SOIC-8 package?
The TLE2141MDG4 in the D-package (SOIC-8) has a junction-to-ambient thermal resistance (θJA) of 97.1°C/W, as specified in the Absolute Maximum Ratings table. This value assumes standard JEDEC 2-layer board conditions. For high-power applications near the 80mA absolute max output current limit, thermal design must ensure junction temperature remains below 150°C - especially at +125°C ambient, where power dissipation headroom is constrained. Use copper pour and thermal vias to improve real-world θJA by 20–30%.
