Product details
Overview
TLE2141QDRQ1 from Texas Instruments is an automotive-grade, low-noise, high-speed precision operational amplifier built on the Excalibur™ complementary bipolar process. It delivers 10.5nV/√Hz input voltage noise at 1kHz, 27V/μs minimum slew rate, 5.9MHz gain-bandwidth product, ±2V to ±22V supply range, and 500μV max input offset voltage at 25°C - enabling high-fidelity signal conditioning in traction inverters and DC/DC converters.
For engineers reviewing the TLE2141QDRQ1 datasheet, TLE2141QDRQ1 pinout, TLE2141QDRQ1 application, or TLE2141QDRQ1 equivalent, key selection considerations include its AEC-Q100 qualification, 10000pF capacitive load drive capability, fast 430ns (0.1%) settling time, rail-to-rail output swing (VCC– + 0.1V to VCC+ – 1V), and robust ±125°C operating temperature range.
Technical Context
The TLE2141QDRQ1 employs a symmetrical input stage achieving simultaneous low audio-band noise (10.5nV/√Hz) and 10Hz 1/f corner, with matched ±40V/μs typical slew rates under 800pF loads. Its all-NPN output stage enables large-swing operation and short-circuit protection with 20mA min output current.
Stable with capacitive loads up to 10nF, it supports low-droop sample-and-holds and direct buffering of long cables (e.g., 4–20mA loops). Input common-mode range extends to VCC– – 0.3V without phase reversal, and CMRR/kSVR remain ≥85dB/≥90dB across –40°C to 125°C.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2141QDRQ1 | FET-input architecture; 1.8nV/√Hz noise; 1MHz GBW; lower input bias current (0.2pA typ). | Better for ultra-high-impedance pH sensors or photodiode amps; unsuitable for high-current drive or >100pF capacitive loads. | Select OPA2141QDRQ1 only when input bias current <1pA and noise <2nV/√Hz are mandatory - not for power-stage signal conditioning. |
| LM7332QMA/NOPB | Rail-to-rail I/O; 20V/μs slew rate; 20MHz GBW; dual-channel; higher quiescent current (2.3mA/ch). | Preferred for space-constrained dual-amplifier functions (e.g., current + voltage sense); less optimized for low-noise single-channel use. | Choose LM7332QMA/NOPB when dual-channel operation and true rail-to-rail output are required - not for lowest-noise monolithic solutions. |
Compared with OPA2141QDRQ1 and LM7332QMA/NOPB, the TLE2141QDRQ1 uniquely balances low 10.5nV/√Hz noise, 27V/μs slew rate, 10nF capacitive load tolerance, and AEC-Q100 Grade 1 qualification - making it the optimal choice for automotive power electronics where noise, speed, and ruggedness coexist.

FAQ
What is the maximum capacitive load the TLE2141QDRQ1 can drive without instability?
The TLE2141QDRQ1 is stable with capacitive loads up to 10000pF, as confirmed in the datasheet's Detailed Description section. At this load level, unity-gain bandwidth reduces to 1.8MHz, but phase margin remains sufficient for reliable operation in sample-and-hold and cable-driving applications. For loads >100pF, layout best practices (short traces, local decoupling) are recommended to maintain 57° minimum phase margin.
Does the TLE2141QDRQ1 support single-supply operation?
Yes, the TLE2141QDRQ1 supports single-supply operation from 4V to 44V total supply range (e.g., 0V and +12V, or 0V and +44V). Its input common-mode range includes the negative rail (VCC– – 0.3V), and output swings to within 0.1V of VCC– and 1V of VCC+, enabling true single-supply functionality in sensor interfaces and industrial PLC analog modules.
Is the TLE2141QDRQ1 pin-compatible with legacy industry-standard op-amps?
Yes - the TLE2141QDRQ1 is explicitly described as a "pin-compatible upgrade" to standard industry products in SOIC-8 packaging. Its pinout matches generic 8-pin op-amp footprints (IN+, IN–, VCC+, VCC–, OUT, and two NC pins), allowing drop-in replacement in existing designs without PCB changes, provided thermal and layout constraints are verified.
What is the guaranteed input offset voltage specification for TLE2141QDRQ1 over temperature?
The TLE2141QDRQ1 guarantees ≤1700μV input offset voltage across the full –40°C to +125°C operating range (per Section 5.5 Electrical Characteristics), with a typical drift of 1.7μV/°C. At 25°C, the maximum is tighter: 900μV (±15V supply) or 1400μV (5V supply), supporting precision applications like battery cell voltage monitoring where offset-induced error must stay below 0.1%.
Can the TLE2141QDRQ1 be used as a comparator, and what is its typical propagation delay?
Yes - the TLE2141QDRQ1 can operate as a comparator. With TTL-level supplies, its open-loop propagation delay is typically 200ns, and saturation recovery time is 150ns. These values make it suitable for overcurrent detection in motor drives where fast fault response (<500ns total latency) is required, though dedicated comparators offer faster performance.
