Product details
Overview
TLE2142ID from Texas Instruments is a dual-channel, high-speed precision operational amplifier with Excalibur bipolar process technology. It delivers 27V/μs minimum slew rate, 5.9MHz gain-bandwidth product, and low input offset voltage (500μV max at 25°C), operating from ±2V to ±22V supplies. It is used in industrial AC-DC power supplies for current-sense amplification and feedback loop conditioning.
For engineers reviewing the TLE2142ID datasheet, TLE2142ID pinout, TLE2142ID application, or TLE2142ID equivalent, key selection criteria include noise performance (10.5nV/√Hz at 1kHz), fast settling time (340ns to 0.1%), output drive capability into 10000pF loads, and operation across –40°C to 105°C industrial temperature range.
Technical Context
The TLE2142ID uses a complementary bipolar Excalibur input stage optimized for simultaneous low audio-band noise (10.5nV/√Hz) and symmetrical slew rate (≥27V/μs). Its internal compensation enables stable unity-gain operation with capacitive loads up to 10000pF without external compensation.
It supports single-supply (4V–44V) or split-supply (±2V–±22V) configurations, features rail-to-rail input common-mode range down to VCC− −0.3V, and provides large output swing (VCC− + 0.1V to VCC+ − 1V) with 20mA short-circuit output current capability.
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) and no offset null pins | Better for low-power, ultra-low-noise instrumentation; unsuitable where manual VIO trim or >±18V operation is required | Select TLE2142ID when offset trimming, high-voltage operation, or robust industrial transients are design priorities |
| AD8620ARZ | Faster slew rate (25V/μs typical vs 27V/μs min), higher GBW (25MHz), but higher input bias current (±1pA vs ±1μA) and no 10000pF drive spec | Preferred for high-speed DAC buffering; less suited for high-capacitance sensor interfaces or high-impedance current sensing | Choose TLE2142ID for proven 10000pF drive, industrial temp range, and fault-tolerant ±44V input rating |
Compared with OPA211IDR and AD8620ARZ, the TLE2142ID uniquely combines manual offset trimming, ±22V operation, 10000pF capacitive drive, and 150ns saturation recovery-making it optimal for ruggedized industrial power control where reliability under stress outweighs ultra-low-noise or ultra-high-speed needs.

FAQ
What is the maximum capacitive load the TLE2142ID can drive without instability?
The TLE2142ID is specified to drive up to 10000pF loads stably without external compensation, as confirmed in the datasheet's "Load capability" feature and operating characteristics tables. This makes it suitable for direct connection to ADC inputs, long cables, or optocoupler LEDs without added series resistance or isolation networks.
Does the TLE2142ID support single-supply operation?
Yes, the TLE2142ID supports single-supply operation from 4V to 44V. Its input common-mode range extends to VCC− −0.3V (i.e., ground in single-supply mode), and output swings to within 0.1V of VCC− and 1V of VCC+, enabling true single-rail functionality in systems like battery-powered FACP modules.
What is the purpose of Pins 1 and 5 on the TLE2142ID?
Pins 1 and 5 are offset null terminals for the first op-amp channel. A 10kΩ potentiometer connected between them-with its wiper to VCC−-allows manual adjustment of input offset voltage to ≤50μV. This capability is retained in the TLE2142ID and is absent in many modern precision op-amps, supporting legacy calibration workflows.
How does the TLE2142ID perform in comparator applications?
The TLE2142ID can be used as a comparator with open-loop propagation delay of ~200ns (TTL levels) and saturation recovery time of 150ns. Its ±44V differential input rating and ability to withstand VCC± inputs without damage make it robust for noisy industrial comparator roles-though dedicated comparators offer faster response and rail-to-rail output.
Is the TLE2142ID rated for automotive applications?
No-the TLE2142ID is characterized for the industrial temperature range (–40°C to 105°C) and carries the 'I' suffix. It is not AEC-Q100 qualified nor rated for automotive use; for automotive designs, TI recommends the TLE2142M (–55°C to 125°C, military grade) or newer automotive-qualified alternatives like the OPA2991QDGKRQ1.
