Product details
Overview
TLE2022CP from Texas Instruments is a dual-channel, precision operational amplifier using the Excalibur bipolar process, delivering 2 MHz unity-gain bandwidth, 0.65 V/µs slew rate, and 150 µV max input offset voltage at ±15 V supply - optimized for low-level signal conditioning in military-grade instrumentation and sensor front-ends.
For engineers reviewing the TLE2022CP datasheet, TLE2022CP pinout, TLE2022CP application, or TLE2022CP equivalent, key selection criteria include its rail-to-rail input capability (down to negative rail), phase-reversal protection, 300 µA max supply current per channel, and guaranteed operation across –55°C to +125°C.
Technical Context
The TLE2022CP employs a complementary bipolar Excalibur process with isolated vertical PNP transistors, enabling higher unity-gain bandwidth and slew rate than legacy OP21-based amplifiers while maintaining precision DC performance. Its bias circuit ensures stable parameters over time and temperature.
It supports both single-supply (5 V) and split-supply (±15 V) operation, features phase-reversal protection to prevent output inversion when inputs go below the negative rail, and offers a common-mode input range extending to the negative supply rail - critical for ground-referenced sensor interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Dual - enables matched-pair signal processing in instrumentation and differential receivers without inter-device mismatch. |
| Unity-gain bandwidth | 2 MHz - supports stable closed-loop operation up to ~1.7 MHz in gain-of-2 configurations with adequate phase margin. |
| Slew rate | 0.65 V/µs - allows clean 10 kHz full-scale sine output at ±10 V swing without distortion in precision DAC buffers. |
| Input offset voltage (max) | 150 µV at ±15 V, 25°C - ensures ≤0.001% gain error in 10 V full-scale 16-bit data acquisition systems. |
| Supply current (max) | 300 µA per channel - enables dual-channel precision amplification in battery-powered systems with <600 µA total quiescent draw. |
| Operating temperature | –55°C to +125°C - qualified for MIL-STD-883 Class B environments including avionics, downhole tools, and engine control modules. |
| Input bias current (max) | 70 nA - permits use with high-impedance sources (e.g., piezoelectric sensors, pH electrodes) without significant DC error. |
Pinout & Package
Ceramic Dual-In-Line Package (CDIP), 8-pin, hermetically sealed - suitable for high-reliability, high-temperature, and low-outgassing applications where plastic packages are prohibited.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting input (Channel 1) | Accepts feedback or inverted signal path; referenced to VCC– for rail-to-rail input operation. |
| 2 | Non-inverting input (Channel 1) | Accepts reference or high-impedance sensor signal; common-mode range includes VCC–. |
| 3 | Output (Channel 1) | Delivers buffered, low-impedance output; capable of ±30 mA short-circuit current. |
| 4 | VCC– / GND | Negative supply or ground reference; must be connected even in single-supply mode (0 V). |
| 5 | Non-inverting input (Channel 2) | Independent second channel input; electrically isolated from Channel 1 with matched specs. |
| 6 | Inverting input (Channel 2) | Second channel inverting node; supports independent feedback networks per channel. |
| 7 | Output (Channel 2) | Second independent output; fully specified for drive strength, noise, and settling under same conditions as Ch1. |
| 8 | VCC+ | Positive supply rail; supports ±2 V to ±20 V operation; decoupling required within 1 cm. |
Key Features
| Feature | Design Value |
|---|---|
| Phase-reversal protection | Prevents catastrophic output inversion when either input falls below VCC–, eliminating latch-up risk in sensor overvoltage events. |
| Rail-to-rail input (to VCC–) | Enables direct interfacing with ground-referenced transducers (e.g., thermocouples, strain gauges) without level-shifting circuitry. |
| Low long-term drift | 0.006 µV/month - ensures calibration stability over 10+ years in unattended monitoring systems without recalibration. |
| High open-loop gain | 6.5 V/µV (136 dB) - guarantees <0.0001% gain error in unity-gain buffer configurations with 10 kΩ load. |
| Low input noise | 19 nV/√Hz at 1 kHz - preserves SNR in low-amplitude signal chains such as medical ECG front-ends or seismic preamps. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision dual op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OP27GP | Higher slew rate (2.8 V/µs), wider bandwidth (8 MHz), but no phase-reversal protection and only commercial temp range (0°C to +70°C). | Lacks military-temperature support and rail-to-rail input; unsuitable for downhole or avionics where input faults or extreme temps occur. | Select OP27GP only for lab-grade, room-temperature, high-speed applications where phase reversal is not a system risk. |
| LM158H | Lower power (350 µA total for dual), lower bandwidth (1 MHz), no phase-reversal protection, and higher VIO (2 mV max). | Qualified to –55°C to +125°C but lacks precision specs needed for 16-bit+ systems; better suited for cost-sensitive industrial controls. | Choose LM158H when absolute precision is secondary to ruggedness and cost in non-critical analog monitoring. |
Compared with OP27GP and LM158H, the TLE2022CP uniquely combines military-temperature operation, phase-reversal immunity, sub-200 µV offset, and 2 MHz bandwidth - making it the only option among the three qualified for precision sensor conditioning in safety-critical, high-reliability embedded systems.

FAQ
What is the maximum operating temperature range for the TLE2022CP?
The TLE2022CP is characterized for continuous operation from –55°C to +125°C, meeting MIL-STD-883 Class B temperature requirements. This rating is validated across all electrical parameters including input offset voltage, supply current, and open-loop gain - ensuring full functionality in engine bays, downhole tools, and avionics bays without derating.
Does the TLE2022CP support single-supply operation?
Yes, the TLE2022CP is explicitly specified for 5 V single-supply operation per the datasheet's Recommended Operating Conditions and Electrical Characteristics tables. Its common-mode input range extends to the negative rail (GND), enabling ground-referenced input signals without level shifting - critical for sensor interfaces in portable and battery-powered systems.
What does "phase-reversal protection" mean for the TLE2022CP?
Phase-reversal protection in the TLE2022CP prevents the output from inverting polarity when either input is driven below the negative supply rail (e.g., during sensor overvoltage or ESD transients). Unlike unprotected op-amps, the TLE2022CP maintains correct output polarity and avoids latch-up - a key reliability feature in unconditioned sensor front-ends.
How does the TLE2022CP compare to the TLE2022AM-MIL variant?
The TLE2022CP uses the same Excalibur die as the TLE2022AM-MIL but is packaged in an 8-pin ceramic DIP (JG) rather than a flatpack. Both share identical electrical specs including 120 µV max VIO at ±15 V and –55°C to +125°C operation. The CP suffix denotes the commercial/military hybrid screening level per TI's ordering nomenclature.
Is the TLE2022CP pin-compatible with standard dual op-amps like the LM358?
No - the TLE2022CP follows the industry-standard dual op-amp pinout (SOIC-8 and CDIP-8): Pin 1 = Ch1–, Pin 2 = Ch1+, Pin 3 = Ch1 out, Pin 4 = V–, Pin 5 = Ch2+, Pin 6 = Ch2–, Pin 7 = Ch2 out, Pin 8 = V+. While this matches LM358's pinout, the TLE2022CP's higher precision, phase-reversal protection, and temperature range make it a functional upgrade - not a drop-in replacement without verifying layout and decoupling compliance.
