Product details
Overview
TLE2022ACD from Texas Instruments is a dual-channel, precision operational amplifier using the Excalibur bipolar process, designed for low-power, high-speed signal conditioning in military-temperature-range applications. It delivers 2 MHz unity-gain bandwidth, 0.65 V/µs slew rate, 150 µV max input offset voltage (at 25°C, ±15 V), 300 µA max supply current, and phase-reversal protection - enabling robust performance in single-supply (5 V) or split-supply (±15 V) configurations.
For engineers reviewing the TLE2022ACD datasheet, TLE2022ACD pinout, TLE2022ACD application, or TLE2022ACD equivalent, key selection considerations include its rail-to-rail input capability (down to negative rail), low long-term drift (0.006 µV/month), stable parameters over –55°C to +125°C, and compatibility with precision sensor front-ends, data acquisition systems, and analog signal chains requiring low noise (19 nV/√Hz) and high CMRR (100 dB).
Technical Context
The TLE2022ACD employs Texas Instruments' complementary bipolar Excalibur process with isolated vertical PNP transistors, enabling significantly improved unity-gain bandwidth and slew rate versus legacy precision op-amps like the OP21. Its bias circuit architecture ensures exceptional stability of offset voltage, supply current, and gain across temperature and time.
It features phase-reversal protection that prevents output inversion when either input falls below the negative supply rail - critical for fault-tolerant instrumentation. The device supports both 5 V single-supply and ±15 V operation, with common-mode input range extending to the negative rail and output swing within 1.3 V of rails under load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Dual - enables matched-pair signal processing (e.g., differential input stage + reference buffer) without inter-device mismatch penalties. |
| Unity-gain bandwidth | 2.8 MHz (typ, ±15 V) - supports stable closed-loop operation up to ~200 kHz in gain-of-10 configurations with adequate phase margin (52°). |
| Slew rate | 0.65 V/µs (typ, ±15 V) - allows clean amplification of 100 kHz sine waves at ±10 V output without slew-induced distortion. |
| Input offset voltage | 150 µV max (25°C, ±15 V) - ensures ≤ 1.5 mV error in 10 V full-scale measurement systems before trimming. |
| Supply current | 700 µA max (full temp range, ±15 V) - enables dual-channel precision amplification with sub-1 mA total quiescent draw. |
| Input noise voltage | 19 nV/√Hz (1 kHz, ±15 V) - contributes < 1.2 µV RMS noise in 10 kHz bandwidth, suitable for µV-level sensor interfacing. |
| CMRR | 100 dB min (25°C, ±15 V) - rejects 100 mV common-mode interference as < 10 µV differential error. |
Pinout & Package
Package: SOIC-8 (D package), surface-mount, 150 mil width. Pin-compatible with industry-standard dual op-amp footprints and reflow-solderable per JEDEC J-STD-020.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting input (Channel 1) | Accepts feedback network connection; referenced to internal input stage with rail-to-rail common-mode range down to V–. |
| 2 | Non-inverting input (Channel 1) | High-impedance input (max 70 nA bias current); supports direct connection to low-current sensors or resistive dividers. |
| 3 | Output (Channel 1) | Capable of ±30 mA output drive; swings to within 1.3 V of rails into 10 kΩ load at ±15 V supply. |
| 4 | V– (Negative supply) | Reference for all internal circuitry; must be connected - floating or reverse-biased operation is not supported. |
| 5 | Non-inverting input (Channel 2) | Electrically identical to Pin 2; independent channel enables dual-path signal conditioning without crosstalk (typical PSRR > 100 dB). |
| 6 | Inverting input (Channel 2) | Matches Pin 1 characteristics; supports identical feedback topologies (inverting, non-inverting, integrator) as Channel 1. |
| 7 | Output (Channel 2) | Independent output stage; no shared resources with Channel 1 - supports simultaneous high-fidelity amplification of two signals. |
| 8 | V+ (Positive supply) | Supports 5 V single-supply or ±15 V dual-supply operation; internal regulation maintains performance across ±2 V to ±20 V range. |
Key Features
| Feature | Design Value |
|---|---|
| Phase-reversal protection | Prevents output latch-up or polarity inversion when inputs go 0.6 V below V–, eliminating need for external clamping diodes in overvoltage-prone sensor interfaces. |
| Military temperature rating | Specified from –55°C to +125°C with guaranteed parametric limits - enables deployment in avionics, downhole tools, and engine-control modules without derating. |
| Low long-term drift | 0.006 µV/month typical offset voltage drift - reduces calibration frequency in metrology equipment and extends recalibration intervals beyond 10 years. |
| Rail-to-rail input capability | Common-mode range includes V– (negative rail) - allows direct interfacing with unipolar sensors (e.g., 4–20 mA receivers, thermocouples) without level-shifting circuitry. |
| Stable supply-current change | ΔICC ≤ 60 µA over full temperature range (±15 V) - minimizes thermal runaway risk and simplifies power budgeting in multi-op-amp systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual precision operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2277UA | Lower offset (10 µV max), higher cost, SOIC-8 but not military-temperature rated (–40°C to +85°C only). | Preferred for commercial lab equipment where ultra-low offset dominates; unsuitable for extended temperature deployments. | Select OPA2277UA only if VIO < 25 µV is mandatory and operating temperature stays within commercial range. |
| LT1013DN8#PBF | Higher supply current (350 µA typ vs 230 µA typ at ±15 V), lower bandwidth (1.2 MHz), same SOIC-8 footprint. | Better long-term stability (0.005 µV/month) but slower response - fits legacy designs needing drop-in replacement with relaxed speed requirements. | Choose LT1013DN8#PBF for cost-sensitive industrial controls where 1 MHz bandwidth suffices and military temp is not required. |
Compared with OPA2277UA and LT1013DN8#PBF, the TLE2022ACD uniquely balances military-temperature operation, 2.8 MHz bandwidth, and 150 µV offset in a standard SOIC-8 - making it the only option among the three qualified for aerospace and defense signal chains demanding simultaneous speed, precision, and environmental ruggedness.

FAQ
What is the maximum operating temperature range for the TLE2022ACD?
The TLE2022ACD is rated for operation from –55°C to +125°C, meeting MIL-PRF-38535 Class B requirements. This full military temperature range is validated across all key parameters including input offset voltage, CMRR, and supply current - ensuring reliable performance in avionics, downhole tools, and engine control units without derating.
Does the TLE2022ACD support single-supply operation?
Yes, the TLE2022ACD is fully specified for 5 V single-supply operation, with common-mode input range extending from 0 V (GND) to 3.2 V and output swing from 0.7 V to 4.3 V (RL = 10 kΩ). Its phase-reversal protection remains active even when inputs fall below GND, making it suitable for unipolar sensor interfaces without external clamping.
What is the typical input bias current of the TLE2022ACD at 25°C?
The TLE2022ACD exhibits a typical input bias current of 33 nA at 25°C (±15 V supply), with a maximum of 70 nA across the full temperature range. This low bias current minimizes voltage errors in high-impedance source applications such as photodiode transimpedance amplifiers or piezoelectric sensor buffers.
How does the phase-reversal protection in the TLE2022ACD function?
The TLE2022ACD incorporates internal circuitry that prevents output polarity inversion when either input is driven more than ~0.6 V below the negative supply rail. Unlike standard op-amps that latch or invert output under such conditions, the TLE2022ACD maintains predictable behavior - eliminating the need for external Schottky clamps in fault-prone industrial or automotive sensor nodes.
Is the TLE2022ACD pin-compatible with other dual op-amps in SOIC-8 packages?
Yes, the TLE2022ACD uses the industry-standard SOIC-8 (D package) pinout: Pin 1 (–IN1), Pin 2 (+IN1), Pin 3 (OUT1), Pin 4 (V–), Pin 5 (+IN2), Pin 6 (–IN2), Pin 7 (OUT2), Pin 8 (V+). It is mechanically and electrically compatible with LM258, TL082, and OPA234 - though electrical performance (bandwidth, noise, offset) differs significantly.
