Product details
Overview
TLE2022CD from Texas Instruments is a dual-channel, precision operational amplifier using Excalibur bipolar process technology, 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 TLE2022CD datasheet, TLE2022CD pinout, TLE2022CD application, or TLE2022CD equivalent, key selection criteria include its rail-to-rail input capability (including negative rail), phase-reversal protection, stable 300 µA max supply current over –55°C to +125°C, and compatibility with both single-5V and split-±15V operation.
Technical Context
The TLE2022CD 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 minimal parameter drift across temperature and time.
This dual op-amp features phase-reversal protection that prevents output inversion when either input falls below the negative supply rail, and supports common-mode input voltage ranges extending to the negative rail - critical for single-supply transducer interfaces and precision difference amplifiers.
Key Specifications

| Channels | Dual independent amplifiers - enables compact two-stage signal conditioning or differential pair implementation without external matching. |
| Unity-gain bandwidth | 2 MHz - supports stable closed-loop operation up to ~1.7 MHz with gain ≥ 2, suitable for anti-aliasing filters and medium-speed data acquisition. |
| Slew rate | 0.65 V/µs - delivers <1 µs settling to 0.1% for 1 V step, adequate for 10-bit ADC drivers and analog multiplexer buffers. |
| Input offset voltage (max) | 150 µV at ±15 V, 25°C - ensures ≤ 1.5 mV error in 10 V full-scale measurement, meeting Class A industrial sensor accuracy requirements. |
| Supply current (max) | 700 µA per channel at ±15 V - enables dual-amplifier operation within 1.4 mA total, ideal for power-constrained military and aerospace modules. |
| Operating temperature | –55°C to +125°C - qualified for extended-range military applications without derating or thermal management overhead. |
| Input bias current (max) | 70 nA - allows use with high-impedance sources (e.g., pH electrodes, piezoresistive sensors) without significant offset contribution. |
Pinout & Package
Package: 8-pin ceramic dual in-line package (CDIP, JG), hermetically sealed for high-reliability military and space applications.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Output of first amplifier - directly drives loads up to ±30 mA; requires no external compensation for unity-gain stability. |
| 2 | 1IN– | Inverting input of first amplifier - accepts signals down to VCC– (negative rail), enabling true single-supply operation. |

IC Role / Device Role: Low-drift, low-noise unity-gain follower isolating reference from load variations and PCB leakage. Use Value: 0.006 µV/mo long-term drift preserves reference integrity over 10+ years; 19 nV/√Hz noise avoids degrading reference SNR. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OP27GP | Higher slew rate (2.8 V/µs), wider bandwidth (8 MHz), but higher supply current (1.2 mA/channel) and no phase-reversal protection. | Better for high-speed active filters; unsuitable where input may go below negative rail without external protection. | Select OP27GP only when speed outweighs rail-to-rail input and low-power requirements. |
| LT1013DN8#PBF | Lower supply current (350 µA/channel), lower noise (12 nV/√Hz), but narrower bandwidth (1.2 MHz) and no guaranteed phase-reversal protection. | Preferred for battery-powered portable instruments; lacks military temp range and robustness for harsh environments. | Choose LT1013DN8#PBF for low-power, low-noise handheld devices - not for extended temperature or high-reliability use. |
Compared with OP27GP and LT1013DN8#PBF, the TLE2022CD uniquely balances military-grade temperature range, phase-reversal immunity, and sub-1 mA power consumption - making it irreplaceable in unattended sensor nodes and avionics signal chains where reliability trumps raw speed or ultra-low noise.

FAQ
What is the maximum supply voltage rating for the TLE2022CD?
The TLE2022CD has an absolute maximum supply voltage rating of +20 V on VCC+ and –20 V on VCC– (or ground in single-supply mode). Operation beyond these limits risks permanent damage. Recommended operating range is ±2 V to ±20 V, with full specifications guaranteed from ±15 V and 5 V configurations.
Does the TLE2022CD support single-supply operation?
Yes, the TLE2022CD is fully specified for single-supply operation at 5 V. Its common-mode input voltage range extends to the negative rail (VCC / GND), and output swings to within 0.95 V of each rail under load - enabling direct interfacing with microcontroller ADCs and digital logic without level-shifting circuitry.
What does "phase-reversal protection" mean for the TLE2022CD?
Phase-reversal protection in the TLE2022CD prevents the output from inverting or latching when either input is driven below the negative supply rail. This eliminates the need for external clamping diodes in applications like grounded thermocouple amplifiers or current-sense circuits where input transients may violate normal common-mode limits.
Is the TLE2022CD pin-compatible with other dual op-amps in the same package?
No - the TLE2022CD uses a non-standard pinout optimized for its Excalibur process and phase-reversal architecture. It is not pin-compatible with industry-standard dual op-amps such as LM358 or TL082 in the 8-pin CDIP (JG) package. Layout must follow the documented pin mapping in Figure 4-2 of the datasheet.
How does the TLE2022CD's long-term drift specification impact system calibration?
The TLE2022CD exhibits a typical long-term input offset voltage drift of 0.006 µV/month, meaning less than 0.072 µV drift per year. In a 10 V full-scale system, this contributes <0.72 ppm/year error - enabling decade-long calibration intervals in metrology and aerospace applications without degradation of accuracy.
