Product details
Overview
TLE2022QDRG4Q1 from Texas Instruments is a dual-channel, AEC-Q100 qualified automotive precision operational amplifier in an 8-pin SOIC package. It delivers 2.8 MHz unity-gain bandwidth, 0.65 V/µs slew rate (±15V), 100 µV max input offset voltage, 300 µA max supply current, and rail-to-rail common-mode input down to the negative rail - enabling high-accuracy signal conditioning in single- or split-supply automotive sensor interfaces.
For engineers reviewing the TLE2022QDRG4Q1 datasheet, TLE2022QDRG4Q1 pinout, TLE2022QDRG4Q1 application, or TLE2022QDRG4Q1 equivalent, this device is selected for low-drift, low-noise analog front-ends in battery management, motor control feedback loops, and automotive body electronics where extended temperature operation (–40°C to +125°C) and phase-reversal protection are mandatory.
Technical Context
The TLE2022QDRG4Q1 uses a proprietary Texas Instruments bipolar process with integrated bias circuitry to stabilize dc parameters across time and temperature. Its architecture supports both ±15V and 5V single-supply operation while maintaining phase-reversal protection - eliminating output inversion when inputs fall below the negative rail.
It features matched dual amplifiers with independent input stages, shared thermal design, and guaranteed performance over full automotive temperature range. The device exhibits minimal supply-current drift (<±10% over –40°C to +125°C) and high open-loop gain (≥0.8 V/µV at ±15V), supporting precision closed-loop configurations in noisy vehicle environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Dual - enables compact dual-signal conditioning (e.g., differential sensing + reference buffer) without inter-channel crosstalk penalties. |
| Supply Voltage Range | ±2V to ±20V dual or 4V to 40V single - supports legacy 12V/24V automotive systems and modern 5V microcontroller interfaces. |
| Input Offset Voltage (max) | ±700 µV over –40°C to +125°C - ensures ≤0.7 mV error in 10-bit ADC front-ends with 3.3V full-scale range. |
| Unity-Gain Bandwidth | 2.8 MHz (±15V) / 1.7 MHz (5V) - sufficient for <100 kHz sensor signal amplification with <1° phase margin degradation. |
| Slew Rate (min) | 0.65 V/µs (±15V) / 0.5 V/µs (5V) - supports clean 100 kHz sine wave output into 10 kΩ load without distortion. |
| Input Bias Current (max) | 90 nA over temperature - allows use with high-impedance sources (e.g., thermistors, piezoelectric sensors) without significant offset shift. |
| ESD Rating | 1000 V HBM - meets MIL-STD-883 Method 3015 for robustness against assembly and in-vehicle electrostatic events. |
Pinout & Package
Package: D (SOIC-8), 8-pin surface-mount, 3.9 mm × 4.9 mm footprint, standard JEDEC MS-012AC. Thermal resistance RθJA = 122.4°C/W - requires minimal copper pour for automotive ambient derating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives external load; capable of ±30 mA short-circuit current. |
| 2 | –IN A | Inverting input channel A - accepts feedback network or inverted signal path. |
| 3 | +IN A | Noninverting input channel A - connects to sensor, reference, or high-impedance source. |
| 4 | V– | Negative supply rail - must be connected to lowest potential (e.g., GND in single-supply, –15V in dual). |
| 5 | +IN B | Noninverting input channel B - electrically isolated from channel A; supports independent second signal path. |
| 6 | –IN B | Inverting input channel B - used for differential configuration or separate gain stage. |
| 7 | OUT B | Amplifier B output - fully independent output stage; shares same thermal and supply constraints as OUT A. |
| 8 | V+ | Positive supply rail - supplies both amplifiers; decoupling capacitor required per TI layout guidelines. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for –40°C to +125°C operation with lifetime reliability testing - eliminates need for additional automotive qualification effort. |
| Phase-reversal protection | Prevents output latch-up or polarity inversion when input falls below V– - critical for sensor signals crossing ground in 12V systems. |
| Rail-to-rail common-mode input | Accepts inputs down to V– (including 0V in single-supply) - enables direct interfacing with unbuffered resistive sensors. |
| Low 1/f noise (0.16 µVPP) | Minimizes drift in DC-coupled applications like battery voltage monitoring over 0.1–10 Hz bandwidth. |
| Stable supply current vs. temperature | ICC remains ≤700 µA across full automotive range - simplifies power budgeting in always-on modules. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV9062-Q1 | Faster slew rate (6.5 V/µs), lower noise (12 nV/√Hz), but higher supply current (560 µA typ) and no phase-reversal protection. | Better for high-speed active filters; unsuitable where input may go below V– (e.g., shunt-based current sensing). | Select TLV9062-Q1 only if bandwidth >5 MHz is required and phase-reversal risk is mitigated externally. |
| OPA2333-Q1 | Zero-drift architecture, 0.02 µV/°C drift, but lower bandwidth (350 kHz) and higher cost; no phase-reversal protection. | Ideal for ultra-low-drift DC measurements (e.g., strain gauge bridges); insufficient for >10 kHz signal paths. | Choose OPA2333-Q1 when offset drift dominates error budget and bandwidth demand is <100 kHz. |
Compared with TLV9062-Q1 and OPA2333-Q1, the TLE2022QDRG4Q1 uniquely balances precision (±700 µV offset), speed (2.8 MHz), and fault resilience (phase-reversal protection) in a cost-effective SOIC-8 package - making it optimal for mid-bandwidth automotive analog signal chains where reliability under transient conditions is non-negotiable.

FAQ
What is the maximum operating temperature range for the TLE2022QDRG4Q1?
The TLE2022QDRG4Q1 is AEC-Q100 Grade 1 qualified and operates reliably from –40°C to +125°C ambient temperature. This rating is validated across all electrical parameters in the datasheet, including input offset voltage, supply current, and open-loop gain - ensuring consistent performance in engine bay and powertrain environments.
Does the TLE2022QDRG4Q1 support single-supply operation at 5V?
Yes, the TLE2022QDRG4Q1 is fully specified for 5V single-supply operation (VCC+ = 5V, VCC– = 0V). Key parameters such as input common-mode range (0 V to 3.2 V), output swing (0.7 V to 3.8 V), and supply current (≤600 µA) are guaranteed across –40°C to +125°C under these conditions.
Is phase-reversal protection active in both dual-supply and single-supply configurations of the TLE2022QDRG4Q1?
Yes, phase-reversal protection is inherent to the TLE2022QDRG4Q1's input stage architecture and functions identically in ±15V dual-supply and 5V single-supply modes. It prevents output inversion when either input falls below the negative supply rail - critical for robustness in automotive systems with ground-referenced sensors.
What is the typical input voltage noise density of the TLE2022QDRG4Q1 at 1 kHz?
The TLE2022QDRG4Q1 has a typical input voltage noise density of 15 nV/√Hz at 1 kHz under ±15V supply conditions. At 5V supply, this increases slightly to 17 nV/√Hz - a value confirmed in Section 5.8 and 5.9 of the official TI datasheet SGLS199C.
Can the TLE2022QDRG4Q1 drive a 10 kΩ load across its full output voltage range at 125°C?
Yes, the TLE2022QDRG4Q1 guarantees ±13.6 V output swing into 10 kΩ at ±15V supply and +125°C (Section 5.8), and 3.8 V to 0.95 V swing into 10 kΩ at 5V supply and +125°C (Section 5.9). These values include worst-case process, voltage, and temperature corners.
