Product details
Overview
TLE2022AQDREP from Texas Instruments is a dual-channel, high-speed, low-power precision operational amplifier engineered for automotive-grade signal conditioning in extended-temperature environments. It delivers 2.8 MHz unity-gain bandwidth, 0.45 V/μs minimum slew rate, and 100 μV maximum input offset voltage at 25°C, operating reliably from −40°C to 125°C with ±15 V or 5 V single-supply capability.
For engineers reviewing the TLE2022AQDREP datasheet, TLE2022AQDREP pinout, TLE2022AQDREP application, or TLE2022AQDREP equivalent, key selection criteria include its rail-to-rail input capability (including negative rail), phase-reversal protection, low 600 μA max supply current, and SOIC-8 packaging optimized for space-constrained automotive sensor interfaces and industrial analog front-ends.
Technical Context
The TLE2022AQDREP employs Texas Instruments' Excalibur complementary bipolar process with isolated vertical PNP transistors, enabling enhanced unity-gain bandwidth and slew rate over legacy precision op-amps like the OP21. Its bias circuit ensures stable dc parameters across temperature and time.
It features phase-reversal protection that prevents output state 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 low-level signal amplification in sensor signal chains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Dual amplifier - enables compact two-stage signal conditioning or differential pair implementation without external matching. |
| Unity-Gain Bandwidth | 2.8 MHz typ at ±15 V - supports stable closed-loop operation up to ~200 kHz for gain-of-10 configurations in anti-aliasing or active filtering. |
| Slew Rate | 0.45 V/μs min at ±15 V - limits full-power bandwidth to ~71 kHz but ensures fidelity for <100 kHz sensor signals with <1 Vpp swing. |
| Input Offset Voltage | 100 μV max at 25°C - reduces dc error to <1 mV in 10× gain stages, minimizing calibration burden in precision measurement systems. |
| Supply Current | 600 μA max per channel - enables ultra-low-power operation in always-on automotive modules with strict quiescent current budgets. |
| Operating Temperature | −40°C to 125°C - qualified for under-hood and transmission-control applications where ambient thermal stress exceeds commercial-grade limits. |
| Input Bias Current | 33 nA max at 25°C - permits use with high-impedance sources (e.g., thermocouples, piezoresistive sensors) without significant voltage drop. |
Pinout & Package
Package: SOIC-8 (D package), surface-mount, 150 mil width, JEDEC MS-012AC compliant. Thermal resistance RθJA = 97°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Output of Amplifier 1 | Delivers buffered, low-impedance output signal; capable of ±30 mA drive into resistive loads. |
| 1IN− | Inverting Input of Amplifier 1 | Differential node for feedback configuration; accepts input down to VCC− (rail-to-rail input). |
| 1IN+ | Non-inverting Input of Amplifier 1 | High-impedance sensing node; includes phase-reversal protection to prevent latch-up on negative overdrive. |
| VCC−/GND | Negative Supply or Ground Reference | Supports split-supply (±15 V) or single-supply (5 V) operation; serves as common reference for both amplifiers. |
| VCC+ | Positive Supply | Accepts up to +20 V; supplies both amplifiers; decoupling recommended within 1 cm of pin. |
| 2OUT | Output of Amplifier 2 | Independent output stage; electrically isolated from 1OUT - allows dual-path signal processing without crosstalk. |
| 2IN− | Inverting Input of Amplifier 2 | Matches 1IN− electrical characteristics; enables matched dual-channel instrumentation topologies. |
| 2IN+ | Non-inverting Input of Amplifier 2 | Identical input structure to 1IN+; supports synchronous dual-sensor conditioning with common-mode rejection. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input including negative rail | Enables direct interfacing with ground-referenced sensors (e.g., RTDs, bridge outputs) in single-supply 5 V systems without level-shifting. |
| Phase-reversal protection | Prevents catastrophic output inversion during input overvoltage transients - eliminates need for external clamping diodes in harsh automotive environments. |
| Low long-term offset drift (0.005 μV/month) | Reduces calibration frequency in safety-critical systems; maintains accuracy over 10+ years of field operation without recalibration. |
| Controlled baseline manufacturing | Single assembly/test site and single fabrication site ensure consistent parametric distribution and traceable lot history for ASIL-B compliance support. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2277UA | Higher precision (10 μV max VIO), lower noise (8 nV/√Hz), but 1.7 mA supply current and only rated to 85°C. | Not qualified for automotive or extended-temp industrial use; lacks phase-reversal protection. | Select when ultimate dc accuracy is required in benign-temperature lab equipment, not in automotive or aerospace deployments. |
| LM2904QDRQ1 | Lower cost, AEC-Q100 qualified, but 7 mV max VIO, 0.3 V/μs slew rate, and no phase-reversal protection. | Suitable for non-critical automotive body electronics, not for engine or safety-related signal paths. | Choose for cost-sensitive, non-precision applications where extended temperature range is needed but dc performance is secondary. |
Compared with OPA2277UA and LM2904QDRQ1, the TLE2022AQDREP uniquely balances automotive-grade temperature range, phase-reversal immunity, and sub-100 μV offset - making it the only option among the three qualified for safety-critical sensor interfaces in harsh environments without design compromises.

FAQ
What is the maximum operating temperature range for the TLE2022AQDREP?
The TLE2022AQDREP is characterized for operation from −40°C to 125°C, meeting automotive under-hood temperature requirements. This rating is validated per JEDEC standards with HAST, temperature cycling, and bond intermetallic life testing - ensuring reliability in continuous high-temperature environments where commercial-grade op-amps would degrade.
Does the TLE2022AQDREP support single-supply operation?
Yes, the TLE2022AQDREP supports true single-supply operation down to 5 V. Its common-mode input voltage range extends to the negative rail (VCC−/GND), allowing direct connection of ground-referenced sensors. Output swing reaches within 0.7 V of each rail under 10 kΩ load, enabling effective use in 5 V data acquisition systems without level-shifting circuitry.
What does "phase-reversal protection" mean for the TLE2022AQDREP?
Phase-reversal protection in the TLE2022AQDREP prevents the output from inverting polarity when either input is driven below the negative supply rail - a failure mode common in standard op-amps during transient overvoltage or sensor disconnect events. This feature eliminates the need for external clamping diodes in automotive and industrial designs, improving system robustness and reducing bill-of-materials count.
How does the TLE2022AQDREP compare to the standard TLE2022 in terms of qualification?
The TLE2022AQDREP is the enhanced-product (EP) version with controlled baseline manufacturing, extended temperature qualification (−40°C to 125°C), and enhanced DMS support. Unlike commercial TLE2022 variants, it includes full qualification pedigree documentation, single-fab/single-test-site traceability, and product-change notification - essential for automotive Tier 1 suppliers and aerospace prime contractors.
Is the TLE2022AQDREP pin-compatible with other dual op-amps in SOIC-8 packages?
The TLE2022AQDREP uses the industry-standard SOIC-8 pinout for dual op-amps (1OUT, 1IN−, 1IN+, VCC−/GND, VCC+, 2OUT, 2IN−, 2IN+), matching pin-for-pin layouts of LM2904, TL082, and OPA234. However, functional compatibility requires verification of supply range, input/output swing, and protection features - especially phase-reversal immunity, which is not present in most pin-compatible alternatives.
