Product details
Overview
TLE2144CDW from Texas Instruments is a quad-channel, low-noise, high-speed precision operational amplifier in SOIC-16 package, featuring 10.5nV/√Hz input voltage noise at 1kHz, 27V/μs minimum slew rate, 5.9MHz gain-bandwidth product, ±2V to ±22V dual-supply operation, and 500μV maximum input offset voltage at 25°C - deployed in EV charging infrastructure signal conditioning and industrial AC-DC feedback loops.
For engineers reviewing the TLE2144CDW datasheet, TLE2144CDW pinout, TLE2144CDW application, or TLE2144CDW equivalent, this page delivers verified specifications, package mapping, functional alternatives, and design-critical settling time (340ns to 0.1%), saturation recovery (150ns), and load drive capability (10000pF) for high-fidelity analog signal paths.
Technical Context
The TLE2144CDW uses TI's Excalibur complementary bipolar process to achieve simultaneous low audio-band noise (10.5nV/√Hz, 10Hz 1/f corner) and symmetrical 40V/μs typical slew rate with up to 800pF capacitive loads. Its fast settling (340ns to 0.1% on 10V step) and low distortion support high-fidelity audio and precision actuator control.
It supports single- or split-supply operation (4V–44V total), features rail-to-rail output swing (VCC− + 0.1V to VCC+ − 1V), and includes internal compensation for unity-gain stability. The device also functions as a comparator with TTL-compatible propagation delay (~200ns) and differential input tolerance up to ±44V without damage.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA4134UA | Lower noise (8nV/√Hz), lower GBW (4MHz), no specified 10000pF load drive | Better for audio; less suitable for high-speed power loop compensation | Select when ultra-low noise dominates over speed and capacitive drive |

FAQ
What is the maximum capacitive load the TLE2144CDW can drive without instability?
The TLE2144CDW is characterized to drive up to 10000pF while maintaining stability and specified performance. This capability eliminates the need for external isolation resistors when interfacing with long traces, cable-connected sensors, or ADC input filters - a key advantage over many general-purpose op-amps that require decompensation above 100–500pF.
Does the TLE2144CDW support single-supply operation?
Yes, the TLE2144CDW operates from a single supply of 4V to 44V. Pin 8 serves as the ground reference in single-supply configurations, and the input common-mode range extends to VCC− (GND) −0.3V, enabling true rail-to-rail input capability near ground - essential for low-voltage sensor interfaces.
What is the guaranteed input offset voltage specification for TLE2144CDW over temperature?
The TLE2144CDW has a maximum input offset voltage of 500μV at 25°C and a temperature coefficient of 1.7μV/°C. Over its full operating range (0°C to 70°C), the worst-case VIO remains within 4.4mV - verified per Section 5.11 of the official datasheet - ensuring predictable DC accuracy in thermal cycling environments.
Can the TLE2144CDW be used as a comparator?
Yes, the TLE2144CDW is explicitly qualified for comparator use. Its open-loop propagation delay is ~200ns with TTL supply levels, and differential inputs tolerate up to ±44V without damage. Saturation recovery is specified at 150ns, enabling reliable high-speed window or threshold detection in FACP and inverter protection circuits.
How does the TLE2144CDW's noise performance compare to standard precision op-amps?
The TLE2144CDW delivers 10.5nV/√Hz at 1kHz and a low 10Hz 1/f corner - significantly quieter than standard precision op-amps like the OP27 (10nV/√Hz but 30Hz corner) or LM324 (40nV/√Hz). This makes the TLE2144CDW especially effective in low-frequency, high-gain stages such as strain gauge or thermocouple amplifiers where 1/f noise dominates error budgets.
