Product details
Overview
TLE2142IP from Texas Instruments is a dual-channel, high-speed precision operational amplifier featuring low 10.5nV/√Hz input voltage noise at 1kHz, 27V/μs minimum slew rate, and 5.9MHz gain-bandwidth product. It operates from ±2V to ±22V supplies and delivers rail-to-rail output swing (VCC− + 0.1V to VCC+ − 1V), making it suitable for precision signal conditioning in industrial AC-DC power supplies and fire alarm control panels.
For engineers reviewing the TLE2142IP datasheet, TLE2142IP pinout, TLE2142IP application, or TLE2142IP equivalent, key selection criteria include its 500μV maximum input offset voltage at 25°C, 10000pF capacitive load drive capability, fast 340ns settling time to 0.1%, and I-suffix industrial temperature range (−40°C to 105°C) for reliable operation in demanding embedded systems.
Technical Context
The TLE2142IP uses TI's Excalibur complementary bipolar process to achieve simultaneous low audio-band noise (10.5nV/√Hz) and symmetrical 40V/μs slew rate with up to 800pF load stability. Its input stage supports differential inputs across full supply rails without damage, enabling robust use in comparator mode.
It features internal compensation, fast saturation recovery (150ns), and open-loop propagation delay of ~200ns under TTL supply conditions - critical for high-fidelity audio amplification and fast actuator positioning where low distortion and tight timing margins are required.

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 1.1nV/√Hz noise, 45MHz GBW, but only 10mA output drive and 36V max supply. | Better for ultra-low-noise audio or instrumentation; unsuitable for high-current loads or >±18V rails. | Select OPA211IDR when noise dominates design requirements and supply voltage stays ≤±18V. |
| AD8620ARZ | 12nV/√Hz noise, 25MHz GBW, JFET input (fA bias current), but limited to ±16V supply and 20mA output. | Preferred for high-impedance sensor interfaces; lacks TLE2142IP's 10000pF load drive and extended voltage range. | Choose AD8620ARZ for pH probes or piezoelectric sensors where input bias current <1pA is critical. |
Compared with OPA211IDR and AD8620ARZ, the TLE2142IP uniquely balances high-voltage operation (±22V), robust capacitive load drive (10000pF), and low 10.5nV/√Hz noise - making it optimal for industrial power electronics where reliability across wide supply and load conditions is non-negotiable.

FAQ
What is the maximum supply voltage rating for the TLE2142IP?
The TLE2142IP has an absolute maximum supply voltage rating of ±22V per rail. Operation beyond this limit risks permanent damage. Recommended operating range is ±2V to ±22V, with full electrical specifications guaranteed across this span at temperatures from −40°C to 105°C. The TLE2142IP maintains specified performance even at the upper end of this range, supporting high-voltage industrial applications such as string inverter monitoring and EV charger BMS circuits.
Does the TLE2142IP support rail-to-rail input or output operation?
The TLE2142IP supports rail-to-rail output swing (VCC− + 0.1V to VCC+ − 1V) but not rail-to-rail input. Its common-mode input voltage range extends from VCC− to VCC+ − 2.1V at ±15V supplies, allowing inputs as low as −15V and as high as +12.9V. This makes the TLE2142IP suitable for high-side sensing and wide-dynamic-range signal conditioning, though input signals must remain within the specified VICR limits to avoid clipping or increased distortion. The TLE2142IP's output stage delivers full swing into heavy loads without external boost circuitry.
Can the TLE2142IP drive large capacitive loads without oscillation?
Yes, the TLE2142IP is explicitly characterized for stable operation with up to 10000pF capacitive loads, a key differentiator versus standard precision op-amps. This capability eliminates the need for series isolation resistors in ADC driver or cable-driving applications. Stability is maintained due to internal compensation optimized for high-capacitance scenarios, and the TLE2142IP retains phase margin >57° under 2kΩ/100pF test conditions. For loads exceeding 10000pF, external compensation may be required - always verify stability in final layout using the TLE2142IP's published small-signal step response.
What is the typical input offset voltage drift over temperature for the TLE2142IP?
The TLE2142IP has a temperature coefficient of input offset voltage (αVIO) of 1.7μV/°C across its full operating range (−40°C to 105°C). This means that over a 145°C temperature span, the offset voltage can drift up to approximately 247μV beyond its 25°C value. At 25°C, the maximum VIO is 500μV, so worst-case total offset at temperature extremes remains within 750μV - well-suited for precision DC-coupled applications like current shunt amplifiers and thermocouple conditioning where long-term accuracy matters. This drift specification applies specifically to the TLE2142IP and is confirmed in TI's SLOS183E datasheet Section 5.9.
Is the TLE2142IP pin-compatible with other devices in the TLE214x family?
Yes, the TLE2142IP is pin-compatible with all TLE2142 variants (e.g., TLE2142CP, TLE2142IDR) and shares the same PDIP-8 footprint and pinout as the TLE2141 and TLE2144 families. This allows drop-in replacement across speed, noise, and channel-count variants without PCB redesign. However, note that TLE2141 (single) and TLE2144 (quad) have identical pin functions per channel but differ in channel count - meaning only one channel of a TLE2144 can substitute for the TLE2142IP in dual-channel designs. The TLE2142IP's I-suffix rating guarantees −40°C to 105°C operation, distinguishing it from C-suffix (0°C to 70°C) versions.
