Product details
Overview
TLE2142MDR from Texas Instruments is a dual-channel, high-speed precision operational amplifier with Excalibur bipolar process technology. It delivers 27V/μs slew rate, 5.9MHz gain-bandwidth product, and ultra-low 10.5nV/√Hz input noise at 1kHz - enabling high-fidelity signal conditioning in EV charging infrastructure and industrial AC-DC power supplies.
For engineers reviewing the TLE2142MDR datasheet, TLE2142MDR pinout, TLE2142MDR application, or TLE2142MDR equivalent, this page provides verified package mapping (SOIC-8), military-grade temperature operation (−55°C to 125°C), output swing capability (VCC− + 0.1V to VCC+ − 1V), and validated alternatives for precision analog front-end design.
Technical Context
The TLE2142MDR integrates a symmetrical input stage optimized for low audio-band noise (10.5nV/√Hz) and fast settling (430ns to 0.1% on 10V step). Its internal compensation supports stable unity-gain operation with 57° phase margin at 5.9MHz, even under 100pF capacitive load.
Designed for split-supply (±2V to ±22V) or single-supply (4V to 44V) use, it features rail-to-rail input common-mode range (−15V to +12.9V at ±15V supply) and robust short-circuit protection (20mA min output current), making it suitable for high-voltage sensor interfaces and actuator drivers.
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 |
|---|---|---|---|
| OPA211IDR | Lower noise (1.1nV/√Hz), lower supply current (3.6mA), but narrower supply range (±2.25V to ±18V) | Better suited for low-power, battery-operated instrumentation; not rated for −55°C to 125°C | Select when ultra-low noise dominates over temperature range and high-voltage operation |
| AD8620ARZ | FEMTO-ampere bias current (1pA), higher CMRR (130dB), but slower slew rate (25V/μs) and no military temp grade | Preferred for high-impedance sensor interfaces (e.g., pH electrodes); lacks short-circuit robustness | Select for ultra-high-impedance sources where input bias current <10pA is mandatory |
Compared with OPA211IDR and AD8620ARZ, the TLE2142MDR uniquely combines military-temperature operation, high-voltage tolerance (±22V), and 27V/μs slew rate - making it irreplaceable in ruggedized power electronics where environmental stress and dynamic performance coexist.

FAQ
What is the maximum operating temperature range for the TLE2142MDR?
The TLE2142MDR is specified for operation from −55°C to +125°C, meeting military-grade temperature requirements per its M-suffix designation. This range is validated across all electrical parameters in the TI datasheet SLOS183E, including input offset voltage drift and output swing performance.
Does the TLE2142MDR support single-supply operation?
Yes, the TLE2142MDR supports single-supply operation from 4V to 44V. Its input common-mode range extends to VCC− (ground), and output swings to within 0.1V of VCC− and 1V of VCC+, enabling true single-rail functionality in systems like industrial PLC analog I/O modules.
What is the purpose of pins 1 and 5 on the TLE2142MDR?
Pins 1 and 5 are offset null terminals used with an external 5kΩ potentiometer and 1kΩ resistor to minimize input offset voltage. Pin 1 connects to the potentiometer wiper; Pin 5 connects to one end of the pot and the 1kΩ resistor tied to VCC− - a configuration confirmed in TI's SLOS183E Figure 1.
Can the TLE2142MDR drive a 1000pF capacitive load stably?
Yes, the TLE2142MDR is explicitly characterized for 1000pF load capability per its datasheet Features section. Unlike many precision op-amps, it maintains stability without external compensation due to its robust internal compensation network optimized for high-capacitance loads.
How does the TLE2142MDR compare to the TLE2142CDR in terms of performance?
The TLE2142MDR offers identical electrical specifications to the TLE2142CDR (e.g., 27V/μs slew rate, 5.9MHz GBW, 10.5nV/√Hz noise) but extends the operating temperature range from 0°C–70°C (C-suffix) to −55°C–125°C (M-suffix), with tighter thermal drift parameters validated across the full military range.
