Product details
Overview
TLE2144CDWR 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 power monitoring.
For engineers reviewing the TLE2144CDWR datasheet, TLE2144CDWR pinout, TLE2144CDWR application, or TLE2144CDWR equivalent, this page delivers verified electrical specifications, package mapping, functional alternatives, and design-critical settling time (340ns to 0.1%), saturation recovery (150ns), and load drive capability (10000pF).
Technical Context
The TLE2144CDWR uses TI's Excalibur complementary bipolar process to achieve simultaneous low audio-band noise (10.5nV/√Hz) and symmetrical 27V/μs slew rate under 800pF loads. Its input stage supports differential inputs up to ±44V without damage and enables comparator operation with 200ns open-loop propagation delay at TTL levels.
It features internal compensation for unity-gain stability, operates across 0°C to 70°C (C-suffix), and delivers rail-to-rail output swing within 0.1V of VCC− and 1V of VCC+, supporting fast actuator positioning and high-fidelity audio amplification where distortion and settling performance are critical.

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA4134UA | Lower noise (8nV/√Hz), lower GBW (4MHz), no specified 10000pF drive capability | Better for audio; less suitable for fast-settling power monitoring | Choose for ultra-low-noise audio or low-power sensor nodes where speed <4MHz suffices |
| LMC6484IMX | Rail-to-rail input/output, higher VIO (1.5mV), lower slew rate (1.3V/μs), CMOS process | Preferred for single-supply, low-voltage (<5V) systems with relaxed speed needs | Choose for battery-powered IoT sensors requiring rail-to-rail operation below 3.3V |
Compared with OPA4134UA and LMC6484IMX, the TLE2144CDWR uniquely balances high slew rate, low 1/f noise, and heavy capacitive load tolerance - making it optimal for industrial power electronics where both precision and speed must coexist under harsh supply conditions.

FAQ
What is the maximum capacitive load the TLE2144CDWR can drive without compensation?
The TLE2144CDWR is characterized to drive up to 10000pF directly without external compensation or isolation resistors. This capability is confirmed in the datasheet under "Load capability" and enables stable operation with long cables, ADC input filters, and relay coil drivers - eliminating additional components in industrial signal chains where layout space and BOM count matter.
Does the TLE2144CDWR support comparator operation, and what is its typical propagation delay?
Yes, the TLE2144CDWR can be used as a comparator. Its open-loop propagation delay is typically 200ns under TTL supply conditions, as stated in the datasheet's Description section. This makes the TLE2144CDWR suitable for overvoltage detection and fast fault-response circuits where dedicated comparators are not required - reducing component count in compact power modules.
What is the guaranteed input offset voltage specification for TLE2144CDWR over temperature?
The TLE2144CDWR has a maximum input offset voltage of 500μV at 25°C and a temperature coefficient of 1.7μV/°C across the full 0°C to 70°C operating range. This means worst-case VIO remains ≤ 500μV + (70°C × 1.7μV/°C) = 619μV, ensuring predictable DC accuracy in battery voltage monitoring and current sense amplification.
Can the TLE2144CDWR operate from a single 5V supply, and what is its output swing in that configuration?
Yes, the TLE2144CDWR supports single-supply operation from 4V to 44V. With a 5V supply (GND = VCC−, 5V = VCC+), its output swings from 0.1V to 4.0V into a ≥2kΩ load - delivering 3.9V of usable dynamic range. This is sufficient for interfacing with 12-bit ADCs and microcontroller analog inputs without level-shifting.
Is the TLE2144CDWR pin-compatible with other devices in the TLE214x family?
Yes, the TLE2144CDWR is pin-compatible with other TLE2144 variants (e.g., TLE2144IDWR, TLE2144ACDWR) in the same SOIC-16 (DW) package. However, it is not pin-compatible with TLE2142 (SOIC-8) or TLE2141 (SOIC-8), nor with quad op-amps having different pinouts like the LM324 or TL074 - always verify pin function alignment using the official TI pin diagram before board reuse.
