Product details
Overview
TLE2022QDREP 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 500 μV maximum input offset voltage at −40°C to +125°C, enabling accurate amplification of low-level sensor signals in engine control units and battery management systems.
For engineers reviewing the TLE2022QDREP datasheet, TLE2022QDREP pinout, TLE2022QDREP application, or TLE2022QDREP equivalent, key selection criteria include its rail-to-rail input capability (including negative rail), phase-reversal protection, ±15 V / 5 V dual-supply operation, and Excalibur-process stability over temperature and time.
Technical Context
The TLE2022QDREP uses Texas Instruments' complementary bipolar Excalibur process with isolated vertical PNP transistors, enabling improved unity-gain bandwidth and slew rate versus legacy precision op-amps like the OP21. Its bias circuit ensures stable DC parameters across temperature and lifetime.
It 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 sensor front-ends and industrial analog I/O modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±2 V to ±20 V or 4 V to 36 V single-supply - supports wide-range industrial and automotive power rails. |
| Unity-Gain Bandwidth | 2.8 MHz typical at ±15 V - enables stable closed-loop operation up to ~200 kHz with gain ≥ 10. |
| Slew Rate | 0.45 V/μs minimum at ±15 V - sufficient for 100 mVpp 100 kHz sine wave without distortion. |
| Input Offset Voltage | 500 μV maximum over −40°C to +125°C - ensures ≤ 5 mV error in 10 V full-scale measurement at worst-case temp. |
| Supply Current per Channel | 700 μA maximum at −40°C to +125°C - enables dual-channel precision amplification under 1.4 mA total quiescent load. |
| Input Bias Current | 70 nA maximum - allows use with high-impedance sources (e.g., thermocouples, pH electrodes) without significant offset shift. |
| CMRR | 91 dB minimum at full temperature range - rejects >12× common-mode interference in noisy engine bay environments. |
Pinout & Package
Package: 8-pin SOIC (D), RoHS-compliant, moisture sensitivity level 3, rated for −40°C to +125°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Output of first amplifier channel - drives loads up to ±30 mA, rail-swing limited to ~1.2 V from rails at ±15 V. |
| 2 | 1IN− | Inverting input of first channel - high-impedance node (70 nA max bias current); requires matched trace impedance for noise rejection. |
| 3 | 1IN+ | Non-inverting input of first channel - supports common-mode range down to VCC−, enabling ground-referenced sensor interfacing. |
| 4 | VCC−/GND | Negative supply or ground reference - must be low-impedance; decoupling capacitor required within 1 cm. |
| 5 | VCC+ | Positive supply - accepts ±2 V to ±20 V or single 4–36 V; internal ESD protection rated to ±2 kV HBM. |
| 6 | 2OUT | Output of second amplifier channel - independently buffered; no crosstalk specification given but layout isolation recommended. |
| 7 | 2IN− | Inverting input of second channel - electrically identical to Pin 2; supports independent feedback networks. |
| 8 | 2IN+ | Non-inverting input of second channel - identical functionality to Pin 3; enables dual-sensor conditioning on one die. |
Key Features
| Feature | Design Value |
|---|---|
| Phase-reversal protection | Prevents output latch-up or polarity inversion when input exceeds negative rail - eliminates need for external clamping diodes in sensor interfaces. |
| Rail-to-rail input (down to VCC−) | Enables direct connection of 0 V–reference transducers (e.g., RTDs, strain gauges) without level-shifting circuitry. |
| Low long-term drift (0.006 μV/month) | Ensures calibration stability over 10+ years in automotive ECUs without field recalibration. |
| Controlled baseline manufacturing | Single assembly/test site and single fab site - guarantees consistent parametric distribution and reduced lot-to-lot variation. |
| Enhanced DMS support | Diminishing Manufacturing Sources mitigation - includes product-change notification and qualification pedigree for long-life programs. |

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 |
|---|---|---|---|
| OPA2333QDGKR | Zero-drift architecture; 10 μV max offset; higher 350 kHz GBW; 17 μA/ch supply current. | Better DC accuracy but lower bandwidth; unsuitable for >100 kHz signal paths. | Select for ultra-low-offset, low-bandwidth sensor nodes where power is constrained. |
| LM2904QDRQ1 | Standard bipolar; 7 mV max offset; 1.2 MHz GBW; 700 μA/ch supply current; no phase-reversal protection. | Lower cost, wider availability, but lacks rail-to-rail input and fails safe during input overvoltage. | Select for non-critical cost-sensitive applications where input stays within rails and offset <7 mV is acceptable. |
Compared with OPA2333QDGKR, TLE2022QDREP offers higher bandwidth and proven phase-reversal immunity at the expense of initial offset; compared with LM2904QDRQ1, it provides guaranteed sub-millivolt offset and failsafe behavior in harsh automotive transients.

FAQ
What is the operating temperature range for the TLE2022QDREP?
The TLE2022QDREP is characterized for continuous operation from −40°C to +125°C, meeting automotive under-hood requirements. This rating is verified per JEDEC standards including biased 85/85 testing, temperature cycling, and HAST - not extrapolated or estimated.
Does the TLE2022QDREP support single-supply operation?
Yes, the TLE2022QDREP operates from a single supply of 4 V to 36 V. Its input common-mode range extends to the negative rail (VCC−/GND), and output swings within ~1.2 V of each rail at ±15 V - enabling true single-supply sensor interface designs without level-shifting circuitry.
What is the maximum input offset voltage specification for TLE2022QDREP over temperature?
The TLE2022QDREP has a maximum input offset voltage of 500 μV over the full −40°C to +125°C operating range. At 25°C, the typical value is 120 μV, and the maximum is 400 μV for the 'A' grade variant - but TLE2022QDREP is the standard grade with 500 μV max limit.
How does phase-reversal protection work in the TLE2022QDREP?
The TLE2022QDREP integrates internal circuitry that prevents output polarity inversion when either input is driven below the negative supply rail. This eliminates the need for external clamping diodes in applications with transient overvoltage or ground bounce - a documented feature confirmed in the device's functional description and absolute maximum ratings section.
Is the TLE2022QDREP pin-compatible with other TLE202x variants?
Yes, all TLE202x dual op-amps in the SOIC-8 (D) package - including TLE2022AQDREP, TLE2022QDREP, and TLE2022MDREP - share identical pinouts. Differences are limited to offset voltage grade (A vs standard), temperature range (Q vs M suffix), and qualification pedigree - not pin function or physical layout.
