Product details
Overview
TLE2144IDW from Texas Instruments is a quad-channel, high-speed precision operational amplifier with low-noise (10.5nV/√Hz at 1kHz), 27V/μs slew rate, 5.9MHz gain-bandwidth product, ±2V to ±22V dual-supply operation, and 500μV max input offset voltage at 25°C - deployed in EV charging infrastructure signal conditioning and industrial AC-DC feedback loops.
For engineers reviewing the TLE2144IDW datasheet, TLE2144IDW pinout, TLE2144IDW application, or TLE2144IDW equivalent, this page delivers verified package mapping (SOIC-16), confirmed noise performance, settling time (340ns to 0.1%), output swing (VCC− + 0.1V to VCC+ − 1V), and real-world comparator use cases in fire alarm control panels and string inverters.
Technical Context
The TLE2144IDW uses TI's Excalibur complementary bipolar process to achieve simultaneous low audio-band noise (10.5nV/√Hz) and symmetrical 27V/μs slew rate under ±15V supply with ≥800pF capacitive load drive capability. Its input stage supports differential inputs up to ±44V without damage.
It features fast saturation recovery (150ns), open-loop propagation delay of ~200ns at TTL levels, and operates as both op amp and comparator. The device maintains stable performance across −40°C to 105°C (I-suffix grade) and supports single-supply (4V–44V) or split-supply (±2V–±22V) configurations.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA4141AIPW | Lower noise (6.5nV/√Hz), lower supply current (1.8mA/ch), but only 1MHz GBW and ±18V max supply | Better for ultra-low-power, low-bandwidth sensor nodes; insufficient for fast-settling power control loops | Select when noise dominates over speed and supply headroom is limited to ±18V |
| LT1499ISW#PBF | Higher precision (50μV VIO), rail-to-rail output, but slower (1.5MHz GBW) and higher noise (12nV/√Hz) | Preferred for DC-critical medical instrumentation; not suitable for high-dV/dt inverter feedback | Select when microvolt-level DC accuracy is required and bandwidth <2MHz suffices |
Compared with TLE2144IDW, OPA4141AIPW trades bandwidth and drive strength for lower power and noise, while LT1499ISW#PBF prioritizes DC precision and rail-to-rail swing at the expense of speed and noise - making TLE2144IDW optimal for high-dynamic-range industrial power control where 27V/μs slew and 5.9MHz GBW are essential.

FAQ
What is the operating temperature range for the TLE2144IDW?
The TLE2144IDW is rated for −40°C to +105°C, matching the I-suffix industrial temperature grade. This range is validated per TI's SLOS183E datasheet Section 5.2 and supports deployment in EV chargers, industrial power supplies, and outdoor FACP enclosures without derating.
Can the TLE2144IDW be used as a comparator?
Yes, the TLE2144IDW can operate as a comparator: its differential inputs tolerate VCC± without damage, and open-loop propagation delay is typically 200ns at TTL levels. However, it lacks dedicated comparator features like internal hysteresis or rail-to-rail output - so external hysteresis is recommended for noisy environments.
What is the maximum capacitive load the TLE2144IDW can drive stably?
The TLE2144IDW is specified to drive ≥1000pF loads stably, per the "Load capability" feature in the datasheet. This is confirmed by characterization showing stable phase margin (>57°) with 100pF load and 2kΩ series resistance - enabling direct connection to ADC inputs or long PCB traces without isolation resistors.
Does the TLE2144IDW have internal input offset voltage nulling?
No, the TLE2144IDW does not include internal offset nulling circuitry. Unlike the TLE2141/2 variants which provide OFFSET N1/N2 pins, the TLE2144IDW (quad version) omits these terminals. Offset correction must be implemented externally via feedback network trimming or digital calibration.
How does the TLE2144IDW's noise performance compare between 10Hz and 1kHz?
The TLE2144IDW exhibits 15nV/√Hz at 10Hz and 10.5nV/√Hz at 1kHz, indicating a 10Hz 1/f noise corner - typical of bipolar input stages. This means low-frequency applications (e.g., sensor DC gain) benefit from tighter filtering, while audio and mid-band signal chains leverage the flatter 10.5nV/√Hz broadband noise floor.
