Product details
Overview
TLE2141ACD from Texas Instruments is a high-speed, low-noise precision operational amplifier in SOIC-8 package, featuring 5.9MHz gain-bandwidth product, 27V/μs minimum slew rate (±15V supply), 10.5nV/√Hz input voltage noise at 1kHz, ±2V to ±22V dual-supply operation, and 500μV maximum input offset voltage at 25°C. It serves signal conditioning and high-fidelity analog front-ends in industrial power electronics.
For engineers reviewing the TLE2141ACD datasheet, TLE2141ACD pinout, TLE2141ACD application, or TLE2141ACD equivalent, key selection criteria include its Excalibur bipolar process enabling symmetrical slew rate and fast settling (430ns to 0.1% on 10V step), rail-to-rail output swing capability (VCC− + 0.1V to VCC+ − 1V), and robust 10000pF capacitive load drive - critical for motor control feedback loops and precision sensor interfaces.
Technical Context
The TLE2141ACD uses TI's complementary bipolar Excalibur process to achieve simultaneous low audio-band noise (10.5nV/√Hz, 10Hz 1/f corner) and symmetrical 40V/μs typical slew rate under 800pF loads. Its input stage supports differential inputs up to ±44V without damage, and open-loop propagation delay is typically 200ns with TTL supply levels.
Designed as a pin-compatible upgrade to legacy industry op-amps, it operates across 0°C to 70°C (C-suffix), supports single (4V–44V) or split (±2V–±22V) supplies, and includes internal compensation for unity-gain stability. Saturation recovery time is 150ns, enabling reliable use in comparator mode with TTL-compatible switching.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 5.9MHz - ensures stable closed-loop operation up to ~5.9MHz at unity gain with 100pF load. |
| Slew rate (min) | 27V/μs at ±15V - enables faithful reproduction of fast transients in servo amplifiers and active filters. |
| Input offset voltage (max) | 500μV at 25°C - reduces DC error in precision instrumentation and current-sense amplification. |
| Input voltage noise | 10.5nV/√Hz at 1kHz - minimizes audible-band distortion in audio preamplifiers and sensor signal chains. |
| Supply voltage range | ±2V to ±22V (dual) or 4V to 44V (single) - supports wide-range industrial rails including 24V and 48V systems. |
| Capacitive load drive | 10000pF - allows direct driving of long cables or ADC input capacitance without external isolation. |
| Settling time | 340ns to 0.1% on 10V step - meets timing requirements in high-speed data acquisition and actuator positioning. |
Pinout & Package
Package: SOIC-8 (D package), 4.9mm × 6mm body size, surface-mount, JEDEC MS-012 compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

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 noise (1.1nV/√Hz), lower VIO (25μV), but only 4.7MHz GBW and limited to ±18V max supply. | Better for ultra-low-noise audio or metrology; less suitable for high-swing industrial power rails. | Choose OPA211IDR when sub-100μV offset and <2nV/√Hz noise dominate; avoid where >±20V rails or >10000pF drive is required. |
| AD8610ARZ | Faster slew rate (25V/μs typ), lower input bias current (1pA), but higher noise (2.5nV/√Hz) and narrower supply (±13V max). | Preferred for high-impedance sensor nodes; not rated for EV charging surge conditions or wide industrial supplies. | Choose AD8610ARZ for FET-input precision needs in battery-powered or low-power systems; verify supply compliance before substituting in 24V/48V designs. |
Compared with OPA211IDR and AD8610ARZ, the TLE2141ACD uniquely balances high-voltage operation (±22V), robust capacitive drive (10000pF), and low 1/f noise - making it irreplaceable in industrial power conversion where rail flexibility and transient resilience outweigh ultra-low-noise optimization.

FAQ
What is the maximum supply voltage rating for the TLE2141ACD?
The TLE2141ACD supports absolute maximum supply voltages of +22V on VCC+ and –22V on VCC−, enabling operation across ±2V to ±22V dual supplies or 4V to 44V single supplies. This wide range accommodates industrial 24V and 48V systems, as well as legacy ±15V designs. Exceeding these limits risks permanent device damage per the Absolute Maximum Ratings table.
Does the TLE2141ACD support rail-to-rail output swing?
The TLE2141ACD does not provide full rail-to-rail output swing. Its specified output voltage range is VCC− + 0.1V to VCC+ − 1V under load, meaning it can swing within 100mV of the negative rail but loses up to 1V headroom at the positive rail. This behavior is consistent across all tested loads and temperatures, and is documented in the Electrical Characteristics tables for both ±15V and 5V supply conditions.
Can the TLE2141ACD be used as a comparator?
Yes, the TLE2141ACD can be used as a comparator. The datasheet explicitly states that both TLE214x and TLE214xA versions support comparator operation, with an open-loop propagation delay of ~200ns under TTL supply levels. However, it lacks built-in hysteresis or latch functionality, so external components are required for noise immunity in noisy environments. Saturation recovery time is 150ns, enabling rapid release from overdrive.
What is the input offset voltage specification for the TLE2141ACD at full temperature range?
The TLE2141ACD has a maximum input offset voltage of 800μV across its full operating temperature range of 0°C to 70°C. At 25°C only, the limit is tighter: 500μV maximum. This is confirmed in Section 5.5 (TLE2141C Electrical Characteristics, VCC± = ±15V), where "Full range" entries specify 800μV for the TLE2141AC grade. Temperature coefficient is 1.7μV/°C, contributing to predictable drift behavior.
Is the TLE2141ACD RoHS compliant and lead-free?
Yes, the TLE2141ACD is RoHS compliant and lead-free. Per Texas Instruments' official packaging information and environmental compliance documentation, the SOIC-8 (D) package variant carries the "Green" designation, indicating halogen-free and lead-free construction meeting JEDEC J-STD-020 moisture sensitivity level 3 and RoHS Directive 2011/65/EU requirements. No exemptions apply.
