Product details
Overview
TLE2142ACD from Texas Instruments is a dual-channel, high-speed precision operational amplifier optimized for low-noise, wide-bandwidth signal conditioning in industrial power electronics. It delivers 5.9MHz gain-bandwidth product, 27V/μs slew rate (±15V supply), 10.5nV/√Hz input voltage noise at 1kHz, ±22V supply range, and 500μV max input offset voltage at 25°C - enabling accurate current sensing and feedback control in EV charging infrastructure.
For engineers reviewing the TLE2142ACD datasheet, TLE2142ACD pinout, TLE2142ACD application, or TLE2142ACD equivalent, this device is selected for demanding analog front-ends where low 1/f noise, fast settling (340ns to 0.1%), rail-to-rail output swing capability, and robust load drive (10000pF) are critical design requirements.
Technical Context
The TLE2142ACD uses TI's Excalibur complementary bipolar process to achieve symmetrical 40V/μs slew rate and low audio-band noise (10.5nV/√Hz at 1kHz with 10Hz 1/f corner). Its input stage supports differential inputs up to ±44V without damage and enables comparator operation with 200ns open-loop propagation delay under TTL supply levels.
Designed for single-supply (4V–44V) or split-supply (±2V–±22V) operation, it features saturation recovery in 150ns and large output swing (VCC− + 0.1V to VCC+ − 1V), making it suitable for fast actuator drivers and high-fidelity audio stages requiring low distortion and high power bandwidth.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 5.9MHz - ensures stable unity-gain operation with phase margin ≥57° into 2kΩ//100pF loads. |
| Slew rate (±15V) | 27V/μs (min) - supports fast transient response in closed-loop current/voltage regulation loops. |
| Input voltage noise | 10.5nV/√Hz at 1kHz - minimizes contribution to system noise floor in precision sensor interfaces. |
| Input offset voltage | 500μV max at 25°C - enables accurate DC-coupled amplification without external trimming in industrial AC-DC systems. |
| Supply voltage range | ±2V to ±22V (split) or 4V to 44V (single) - accommodates wide-input industrial power rails and battery-backed designs. |
| Settling time | 340ns to 0.1% on 10V step - meets timing constraints in high-speed data acquisition and positioning control. |
| Output drive | 10000pF capacitive load - allows direct interface to long cables or ADC input filters without stability loss. |
Pinout & Package
Package: SOIC-8 (D package), 4.9mm × 6mm body size, surface-mount, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Offset Null (N1) | Connects to internal 5kΩ resistor for manual input offset adjustment via external potentiometer. |
| 2 | Inverting Input (IN−) | Differential input node; accepts common-mode voltage from VCC− to VCC+ − 0.3V. |
| 3 | Non-inverting Input (IN+) | Differential input node; supports full rail-to-rail common-mode range under specified conditions. |
| 4 | VCC− | Negative supply rail (split) or ground (single); must be decoupled near pin for stability. |
| 5 | Offset Null (N2) | Connects to internal 1kΩ resistor; used with Pin 1 for offset nulling circuit implementation. |
| 6 | Output (OUT) | Amplified output capable of swinging within 0.1V of VCC− and 1V of VCC+ under load. |
| 7 | VCC+ | Positive supply rail; supports up to +22V (absolute max) with thermal derating above 70°C. |
| 8 | NC | No connect - internally unused; must remain unconnected per datasheet guidance. |
Key Features
| Feature | Design Value |
|---|---|
| Low 1/f noise corner | 10Hz - preserves signal integrity in DC-coupled instrumentation and slow-varying sensor outputs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA211IDR | Lower noise (1.1nV/√Hz), lower offset (25μV), but only 45MHz GBW and 27V/μs slew rate; requires ±18V max supply. | Better for ultra-low-noise DC precision; less suitable for high-slew, wide-supply industrial transients. | Select when sub-μV offset and nanovolt noise dominate over supply flexibility and capacitive drive. |
| AD8610ARZ | Higher slew rate (25V/μs), lower offset (120μV), but narrower supply range (±13V max) and higher 1/f corner (30Hz). | Preferred for high-speed DAC buffer or precision instrumentation; not rated for 44V single-supply operation. | Choose for low-offset, low-distortion audio or medical signal paths where supply headroom is constrained. |
Compared with OPA211IDR and AD8610ARZ, the TLE2142ACD uniquely balances wide supply range (±22V), robust 10000pF drive, and low 10Hz 1/f corner - making it optimal for industrial power conversion where reliability under harsh voltage transients and capacitive loading is non-negotiable.

FAQ
What is the maximum capacitive load the TLE2142ACD can drive stably?
The TLE2142ACD is characterized to drive up to 10000pF capacitive loads without oscillation or phase margin degradation, as confirmed in the datasheet's operating characteristics section. This capability eliminates the need for external isolation resistors in applications such as ADC input buffering or long-cable transmission, provided proper PCB layout and supply decoupling are maintained per TI's recommended guidelines for the TLE2142ACD.
Does the TLE2142ACD support single-supply operation?
Yes, the TLE2142ACD supports true single-supply operation from 4V to 44V, with input common-mode range extending to VCC− (ground) and output swing reaching within 0.1V of VCC−. Its input stage remains functional with inputs at ground potential, and its rail-to-rail output capability (VCC− + 0.1V to VCC+ − 1V) enables direct interfacing with microcontrollers and ADCs in 3.3V or 5V systems powered from a single rail - all verified in the TLE2142ACD's recommended operating conditions table.
What is the input offset voltage specification for the TLE2142ACD over temperature?
The TLE2142ACD has a maximum input offset voltage of 500μV at 25°C and a temperature coefficient of 1.7μV/°C across the full 0°C to 70°C operating range. At the extremes of that range, the offset remains within 2200μV (max), as specified in Section 5.7 of the datasheet. This predictable drift behavior allows for reliable DC accuracy in closed-loop industrial controls without active calibration - a key design value confirmed for the TLE2142ACD.
Can the TLE2142ACD be used as a comparator?
Yes, the TLE2142ACD is explicitly documented to operate as a comparator, with typical open-loop propagation delay of 200ns under TTL supply levels and differential input tolerance up to ±44V without damage. Its fast saturation recovery (150ns) and ability to maintain VCC± differential inputs make it suitable for overvoltage/overcurrent fault detection in power systems - though external hysteresis is recommended for noise immunity, as noted in the TLE2142ACD's functional description.
What package type is used for the TLE2142ACD?
The TLE2142ACD is supplied in an 8-pin SOIC (Small Outline Integrated Circuit) package, designated "D" by Texas Instruments, with nominal dimensions of 4.9mm × 6mm. This surface-mount package is RoHS-compliant, JEDEC-standardized, and thermally rated at θJA = 97.1°C/W - enabling reliable thermal performance in densely populated industrial PCBs without requiring heatsinking, as validated in the TLE2142ACD's mechanical and packaging documentation.
