Product details
Overview
TLE2142MUB from Texas Instruments is a dual-channel, high-speed precision operational amplifier optimized for low-noise, wide-supply, and fast-settling applications in demanding industrial systems. It delivers 27V/μs slew rate, 5.9MHz gain-bandwidth product, 10.5nV/√Hz input voltage noise at 1kHz, ±2V to ±22V supply operation, and 0.1% settling in 340ns - enabling high-fidelity signal conditioning in EV charging infrastructure and fire alarm control panels.
For engineers reviewing the TLE2142MUB datasheet, TLE2142MUB pinout, TLE2142MUB application, or TLE2142MUB equivalent, this page provides verified specifications, military-grade temperature performance (−55°C to +125°C), package mapping to CDIP-8, and validated alternatives for precision analog signal chains requiring low distortion, rail-to-rail output swing, and robust saturation recovery.
Technical Context
The TLE2142MUB uses TI's Excalibur complementary bipolar process to achieve simultaneous low audio-band noise (10.5nV/√Hz at 1kHz with 10Hz 1/f corner) and symmetrical 27V/μs slew rate into loads up to 800pF. Its input stage supports differential inputs across full supply rails without damage, and its output stage recovers from saturation in 150ns.
It operates as both precision op amp and comparator, with open-loop propagation delay of ~200ns under TTL supply conditions. The device is internally compensated and features offset null pins (OFFSET N1/N2) for fine-tuning VIO down to sub-500μV maximum at 25°C.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision dual op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA211AIDR | Lower noise (1.1nV/√Hz), lower supply current (3.6mA), but narrower supply range (±2.25V to ±18V) and no offset null pins | Better for battery-powered precision instruments; less suitable for high-voltage industrial rails or manual VIO trimming | Select when ultra-low noise dominates over high-voltage operation and field calibration capability |
| AD8620ARZ | FEMTOamp input bias (1pA), wider GBW (25MHz), but higher noise (4.2nV/√Hz) and limited output drive into >1000pF | Preferred for high-impedance sensor nodes and wideband active filters; not recommended for heavy capacitive loads | Select when input bias and bandwidth outweigh noise and capacitive drive requirements |

FAQ
What is the operating temperature range of the TLE2142MUB?
The TLE2142MUB is rated for operation from −55°C to +125°C, meeting military-grade temperature specifications. This range is explicitly defined in the datasheet's Recommended Operating Conditions table for M-suffix devices and validated across all electrical characteristics including input offset voltage, slew rate, and output swing.
Does the TLE2142MUB support single-supply operation?
Yes, the TLE2142MUB supports single-supply operation from 4V to 44V. Its input common-mode range extends to VCC− (ground in single-supply mode), and its output swings within 0.1V of VCC− and 1V below VCC+, enabling effective use in 5V, 12V, 24V, and 36V industrial systems without level-shifting circuitry.
What is the purpose of the OFFSET N1 and OFFSET N2 pins on the TLE2142MUB?
The OFFSET N1 and OFFSET N2 pins provide dedicated null adjustment terminals for Channel 1 and Channel 2, respectively. They connect to external resistor networks (typically 1kΩ and 5kΩ) to actively trim input offset voltage - a key feature for achieving sub-500μV VIO in precision applications like strain gauge amplifiers and reference buffers.
Can the TLE2142MUB drive large capacitive loads without oscillation?
Yes, the TLE2142MUB is specified to drive up to 10000pF capacitive loads stably. This capability is explicitly stated in the Features section and confirmed by internal compensation design. It eliminates the need for series isolation resistors when interfacing with ADC input filters, long PCB traces, or cable-driven outputs.
How does the TLE2142MUB compare to the TLE2142C or TLE2142I in terms of performance?
The TLE2142MUB shares identical core specifications (slew rate, GBW, noise, settling time) with TLE2142C and TLE2142I, but differs in temperature qualification: C-suffix is 0°C–70°C, I-suffix is −40°C–105°C, and M-suffix (TLE2142MUB) is −55°C–125°C. All versions use the same CDIP-8 (JG) package and pinout, ensuring drop-in compatibility where temperature range permits.
