Product details
Overview
TLE2144MDW from Texas Instruments is a quad-channel, high-speed precision operational amplifier with Excalibur complementary bipolar process technology. It delivers 27V/μs minimum slew rate, 5.9MHz gain-bandwidth product, and low input offset voltage (500μV max at 25°C), operating from ±2V to ±22V supplies. It is used in industrial AC-DC power supplies and fire alarm control panels where fast settling (340ns to 0.1%) and robust output drive (20mA short-circuit current) are critical.
For engineers reviewing the TLE2144MDW datasheet, TLE2144MDW pinout, TLE2144MDW application, or TLE2144MDW equivalent, key selection criteria include its military-grade temperature range (−55°C to 125°C), SOIC-16 package, low 10.5nV/√Hz noise at 1kHz, and ability to drive 1000pF loads while maintaining stability - essential for precision sensor signal conditioning and high-fidelity analog front-ends.
Technical Context
The TLE2144MDW integrates a symmetrical input stage optimized for low audio-band noise (10.5nV/√Hz at 1kHz, 10Hz 1/f corner) and high slew rate (27V/μs min), enabling low-distortion performance in wideband applications. Its internal compensation ensures unity-gain stability with capacitive loads up to 1000pF without external compensation.
It supports single-supply (4V–44V) and split-supply (±2V–±22V) operation, with rail-to-rail input common-mode range extending to VCC− −0.3V and output swing from VCC− +0.1V to VCC+ −1V. Saturation recovery time is 150ns, and open-loop propagation delay is ~200ns under TTL supply conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Slew Rate | 27V/μs minimum - enables accurate reproduction of fast transients in motor control feedback or ADC driver stages. |
| Gain-Bandwidth Product | 5.9MHz - supports stable closed-loop gain ≥10 at >500kHz, suitable for active filters and precision instrumentation amplifiers. |
| Input Offset Voltage | 500μV maximum at 25°C - ensures <0.05% error in 1V full-scale measurement systems without trimming. |
| Supply Voltage Range | ±2V to ±22V (or 4V to 44V single) - compatible with industrial 24V rails and legacy ±15V analog systems. |
| Output Drive Capability | 20mA short-circuit current - drives heavy loads like relay coils or long cables without gain compression. |
| Input Voltage Noise | 10.5nV/√Hz at 1kHz - preserves SNR in low-level sensor interfaces such as strain gauge or thermocouple amplifiers. |
| Settling Time | 340ns to 0.1% on 10V step - meets timing budgets in high-speed data acquisition and actuator positioning loops. |
Pinout & Package
Package: SOIC-16 (DW), 10.3mm × 10.3mm body size, surface-mount, plastic, with standard JEDEC outline and thermal impedance θJA = 57.3°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 10, 14 | Inverting Input (−) | Four independent op-amp inverting inputs; each accepts common-mode voltage down to VCC− −0.3V. |
| 2, 6, 9, 13 | Non-Inverting Input (+) | Four independent op-amp non-inverting inputs; fully differential input protection allows ±44V differential rating. |
| 3, 7, 11, 15 | Output | Four buffered outputs capable of sourcing/sinking 20mA; swing within 1V of rails under load. |
| 4 | VCC− | Negative supply pin for all four amplifiers; must be decoupled locally for stability. |
| 16 | VCC+ | Positive supply pin for all four amplifiers; shared rail supports synchronized biasing across channels. |
| 8 | GND | Analog ground reference; separate from digital ground in mixed-signal systems to minimize noise coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Low-noise input stage | 10.5nV/√Hz at 1kHz with 10Hz 1/f corner - minimizes contribution to total system noise in precision DC-coupled chains. |
| Capacitive load drive | Stable with ≥1000pF loads - eliminates need for isolation resistors in DAC output buffers or cable drivers. |
| Fast saturation recovery | 150ns recovery from overdrive - prevents pulse distortion in comparator-mode operation or transient overload scenarios. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA4134MD | FET-input (not bipolar); lower input bias current (1pA vs 2μA), higher VIO (1mV max), slower slew rate (20V/μs). | Better for ultra-high-impedance pH or piezoelectric sensors; less suitable for high-current drive or low-noise DC-coupled amps. | Select when input leakage dominates error budget and speed requirements are relaxed. |
| LMC6084IMX | CMOS input; rail-to-rail I/O; wider supply (2.7V–15.5V); lower slew rate (0.35V/μs); higher noise (22nV/√Hz). | Optimized for low-voltage battery-powered instrumentation; unsuitable for ±15V industrial systems or fast settling needs. | Choose only for portable, low-power, single-supply designs where speed and noise are secondary. |
Compared with OPA4134MD and LMC6084IMX, the TLE2144MDW uniquely combines military-grade temperature range, bipolar low-noise performance, high output drive, and fast settling - making it irreplaceable in demanding industrial power electronics where all four attributes are simultaneously required.

FAQ
What is the operating temperature range of the TLE2144MDW?
The TLE2144MDW is rated for operation from −55°C to +125°C, meeting MIL-PRF-38535 Class B requirements. This military-grade temperature range is confirmed in Section 5.2 of the official TI datasheet (SLOS183E) and validated across all electrical characteristics tables for the M-suffix variant. The TLE2144MDW maintains specified performance - including 500μV max input offset voltage and 27V/μs min slew rate - across this full range.
Does the TLE2144MDW support single-supply operation?
Yes, the TLE2144MDW supports single-supply operation from 4V to 44V, as explicitly stated in the "Features" section and Table 5.2 (Recommended Operating Conditions). Its input common-mode range extends to VCC− −0.3V, and output swings to within 1V of either rail - enabling true single-supply use in applications like 24V industrial sensors without level-shifting circuitry.
Can the TLE2144MDW drive a 1000pF capacitive load stably?
Yes, the TLE2144MDW is characterized to drive ≥1000pF loads without oscillation, per the "Load capability: 10000pF" specification in the Features list. This is enabled by its internal compensation and verified in typical characteristics plots (Section 5.42). For reliable stability, maintain proper PCB layout: local 0.1μF ceramic decoupling at pins 4 (VCC−) and 16 (VCC+), and minimize trace inductance to the load.
What is the input voltage noise density of the TLE2144MDW at 1kHz?
The TLE2144MDW has an input voltage noise density of 10.5nV/√Hz at 1kHz, as specified in both the Features list and Table 5.4 (TLE2141C Operating Characteristics). This value is consistent across all TLE214x variants and is measured with RS = 20Ω under VCC± = ±15V, TA = 25°C conditions - confirming its suitability for low-noise precision amplification tasks.
Is the TLE2144MDW pin-compatible with other TLE214x variants in SOIC-16?
No - the TLE2144MDW uses SOIC-16 (DW), while other TLE214x devices like TLE2142 and TLE2141 are offered in SOIC-8 (D) or PDIP-8 packages. Only TLE2144-series parts (e.g., TLE2144, TLE2144A, TLE2144M-D) share the SOIC-16 footprint. Pin mapping is identical across TLE2144x DW variants, but not with TLE2141/TLE2142 families due to differing channel count and pinout.
