Product details
Overview
TLE2141CDRG4 from Texas Instruments is a low-noise, high-speed precision operational amplifier in an 8-pin SOIC package, featuring 10.5nV/√Hz input voltage noise at 1kHz, 27V/μs minimum slew rate, and 5.9MHz gain-bandwidth product. It operates from ±2V to ±22V supplies and delivers rail-to-rail output swing within 1V of rails, suited for high-fidelity audio signal conditioning and fast actuator control loops.
For engineers reviewing the TLE2141CDRG4 datasheet, TLE2141CDRG4 pinout, TLE2141CDRG4 application, or TLE2141CDRG4 equivalent, key selection criteria include its 500μV maximum input offset voltage at 25°C, 1000pF capacitive load drive capability, fast 340ns settling time to 0.1%, and Excalibur bipolar process enabling symmetrical slew rate and low distortion in precision analog front-ends.
Technical Context
The TLE2141CDRG4 uses TI's complementary bipolar Excalibur process to achieve simultaneous low 10Hz 1/f noise corner (15nV/√Hz) and symmetrical 40V/μs typical slew rate. Its input stage supports differential inputs up to ±44V without damage, and it maintains stable operation driving loads up to 1000pF.
It functions as both precision op-amp and comparator with TTL-compatible open-loop propagation delay (~200ns) and 150ns saturation recovery. The device is internally compensated and characterized for 0°C to 70°C operation (C-suffix), with pin-compatible variants including tighter-offset TLE2141ACDRG4.

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 1.1nV/√Hz noise, but only 4.5MHz GBW and 2.2V/μs slew rate; requires dual supply or level-shifting for ±15V use | Better for ultra-low-noise DC applications; less suitable for fast-settling AC-coupled circuits | Select OPA211IDR when sub-2nV/√Hz noise dominates over speed; retain TLE2141CDRG4 for combined low-noise + high-slew performance |
| AD8610ARZ | Faster 25V/μs slew rate and lower 0.25μV/°C drift, but limited to ±18V max supply and no 1000pF load drive spec | Preferred for high-precision instrumentation with tight thermal drift budgets | Choose AD8610ARZ for <1μV/°C drift-critical systems; choose TLE2141CDRG4 for robust 1000pF drive and wider ±22V supply range |
Compared with OPA211IDR and AD8610ARZ, the TLE2141CDRG4 uniquely balances 10.5nV/√Hz noise, 27V/μs slew rate, and 1000pF capacitive load drive in a ±22V-rated SOIC-8, making it optimal for industrial power electronics where both precision and dynamic response are required without layout redesign.

FAQ
What is the maximum capacitive load the TLE2141CDRG4 can drive stably?
The TLE2141CDRG4 is specified to drive up to 1000pF capacitive loads without oscillation or excessive overshoot. This capability is verified in TI's datasheet Section 5.6 under operating characteristics with CL = 500pF and confirmed by stability testing across temperature and supply conditions. For loads exceeding 1000pF, external isolation resistance or compensation network design is recommended. The TLE2141CDRG4 achieves this via internal compensation optimized for the Excalibur bipolar process.
Does the TLE2141CDRG4 support single-supply operation?
Yes, the TLE2141CDRG4 supports single-supply operation from 4V to 44V total supply range (e.g., 0V and +12V, or 0V and +24V). Its input common-mode range extends to VCC− (ground in single-supply) and its output swings to within 0.1V of VCC− and 1V of VCC+, enabling true single-supply functionality in sensor interfaces and portable equipment. The TLE2141CDRG4 datasheet specifies VICR and VOM parameters explicitly for VCC = 5V operation.
What is the input offset voltage specification for the TLE2141CDRG4 at full temperature range?
The TLE2141CDRG4 has a maximum input offset voltage of 1300μV across its full operating temperature range of 0°C to 70°C, as stated in Section 5.5 of the TI datasheet under "TLE2141C Electrical Characteristics" at VCC± = ±15V. At 25°C only, the limit is tighter: 900μV maximum. This parameter is measured with RS = 50Ω and VIC = 0V, and reflects guaranteed performance for production units. The TLE2141CDRG4 uses Excalibur process trimming to achieve this C-grade accuracy.
Can the TLE2141CDRG4 be used as a comparator?
Yes, the TLE2141CDRG4 can be used as a comparator, with typical open-loop propagation delay of 200ns under TTL supply levels and 150ns saturation recovery time. However, it lacks dedicated comparator features like internal hysteresis or rail-to-rail output swing - its output saturates within 1V of each rail. For non-critical threshold detection where speed and precision are secondary to analog versatility, the TLE2141CDRG4 serves as a functional comparator. For high-speed or low-power comparator applications, purpose-built devices are preferred.
What is the thermal resistance (θJA) of the TLE2141CDRG4 in its SOIC-8 package?
The TLE2141CDRG4 in the D (SOIC-8) package has a junction-to-ambient thermal resistance (θJA) of 97.1°C/W, as specified in Section 5.1 "Absolute Maximum Ratings" of the TI datasheet. This value assumes standard JEDEC 2-layer board mounting per JESD 51-7. Actual thermal performance depends on PCB copper area, airflow, and adjacent heat sources. The TLE2141CDRG4's 4.4mA typical supply current and 30Ω open-loop output impedance contribute to moderate power dissipation, supporting reliable operation in enclosed industrial enclosures.
