Product details
Overview
TLE2074MJB from Texas Instruments is a quad-channel JFET-input operational amplifier optimized for high-voltage, low-noise, high-speed precision applications. It delivers ±19V supply operation, 10MHz unity-gain bandwidth, 32V/μs slew rate, 17nV/√Hz input voltage noise at 1kHz, and ±15pA input bias current - enabling accurate signal conditioning in electricity meters and oscilloscope front-ends.
For engineers reviewing the TLE2074MJB datasheet, TLE2074MJB pinout, TLE2074MJB application, or TLE2074MJB equivalent, this page provides verified package mapping (CERDIP-14), validated electrical specifications across −55°C to +125°C, confirmed quad-channel architecture with independent offset null pins, and real-world use cases in AC drive power stages and flight control units.
Technical Context
The TLE2074MJB implements a JFET-input stage with on-chip Zener trimming for DC precision, supporting rail-to-rail differential input operation up to ±19V supplies. Its wide bandwidth and low noise floor stem from Excalibur process optimization, not external compensation.
It operates as a unity-gain stable voltage feedback amplifier with 56° phase margin, 10.6MHz gain-bandwidth product, and 300kHz maximum output-swing bandwidth under 25pF load - suitable for closed-loop configurations without stability risk.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA4134UA | Lower input noise (8nV/√Hz), but only ±18V max supply and no CERDIP packaging. | Preferred in audio-grade instrumentation where noise dominates; unsuitable for military/avionics due to plastic SOIC-only availability. | Select when lower noise is critical and extended temperature range is not required. |
| LMC6084IMX | CMOS input (0.01pA bias), but only 1.4MHz GBW and ±8V supply limit. | Better for ultra-high-Z sensor interfaces (e.g., pH probes); insufficient bandwidth for oscilloscope front-ends or fast current sensing. | Select for picoampere-level bias-critical applications with moderate speed requirements. |
Compared with OPA4134UA and LMC6084IMX, the TLE2074MJB uniquely combines hermetic CERDIP-14 packaging, −55°C to +125°C operation, ±19V supply, and 10MHz bandwidth - making it the only option qualified for high-reliability industrial and aerospace signal chains requiring simultaneous precision, speed, and ruggedness.

FAQ
What is the operating temperature range of the TLE2074MJB?
The TLE2074MJB is rated for operation from −55°C to +125°C, as confirmed by its M-suffix designation and electrical characteristics tables covering that full range. This makes the TLE2074MJB suitable for deployment in harsh environments such as engine compartments, avionics bays, and outdoor utility metering installations where ambient temperatures exceed commercial or industrial grade limits.
Does the TLE2074MJB require external compensation for unity-gain stability?
No, the TLE2074MJB is unity-gain stable per its datasheet specifications, with 56° phase margin measured at unity gain under standard test conditions. It does not require external compensation capacitors when used in buffer, inverter, or follower configurations - simplifying layout and reducing bill-of-materials cost in high-speed analog designs.
What is the purpose of the offset null pins on the TLE2074MJB?
The TLE2074MJB includes dedicated offset null pins (OFFSET N1 and OFFSET N2) tied to internal trimming resistors. These allow fine adjustment of input offset voltage using external potentiometers - critical for applications like precision weigh scales and calibration equipment where sub-millivolt DC accuracy must be maintained over time and temperature without software correction.
How does the TLE2074MJB compare to the TLE2074CDW in terms of performance and packaging?
The TLE2074MJB uses a hermetically sealed CERDIP-14 (J) package rated for −55°C to +125°C, while the TLE2074CDW is a plastic SOIC-14 (DW) variant rated only from 0°C to 70°C. Electrically, the TLE2074MJB has higher max input offset voltage (5mV vs 3mV) but identical bandwidth, slew rate, and noise - reflecting its focus on ruggedness and extended temperature operation over ultra-low initial offset.
Can the TLE2074MJB drive a 600Ω load effectively?
Yes, the TLE2074MJB specifies large-signal differential voltage amplification of 80dB minimum into a 600Ω load, and its output swing remains within specification (±1.5V min at ±20mA) under that condition. This confirms robust drive capability for legacy test equipment interfaces, video line drivers, and other 600Ω-terminated systems without external buffering.
