Product details
Overview
TLE2022AQDRQ1 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, and 300 µA max supply current across –40°C to +125°C - enabling high-accuracy signal conditioning in battery management and motor control circuits.
For engineers reviewing the TLE2022AQDRQ1 datasheet, TLE2022AQDRQ1 pinout, TLE2022AQDRQ1 application, or TLE2022AQDRQ1 equivalent, key selection criteria include its rail-to-rail input capability (to negative rail), phase-reversal protection, low 19 nV/√Hz input voltage noise at 10 Hz, and guaranteed performance under single-5V or split-±15V supply conditions.
Technical Context
The TLE2022AQDRQ1 employs a proprietary Texas Instruments bipolar process with integrated bias circuitry, delivering exceptional stability of dc parameters over temperature and time. Its architecture supports both single-supply (5V) and dual-supply (±15V) operation while maintaining common-mode input range extending to the negative rail - critical for low-side current sensing and sensor interfacing in automotive systems.
Phase-reversal protection prevents output polarity inversion when inputs fall below the negative supply, eliminating fault-induced system errors. The device achieves 106 dB typical CMRR and 115 dB PSRR at ±15V, ensuring robust rejection of supply and common-mode disturbances in noisy vehicle electrical environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Dual - enables compact dual-path signal conditioning (e.g., differential pair amplification or independent sensor channels) without board-level duplication. |
| Supply Voltage Range | ±2 V to ±20 V dual or 4 V to 40 V single - supports direct integration into 12V/24V automotive power domains with 5V or ±15V logic compatibility. |
| Input Offset Voltage (max) | 120 µV at 25°C, 700 µV over –40°C to +125°C - ensures sub-millivolt error in precision current/voltage measurement circuits across full automotive temperature range. |
| Unity-Gain Bandwidth | 2.8 MHz (±15V) - sufficient for closed-loop response in motor position feedback, OBC voltage regulation, and BMS cell balancing control loops. |
| Slew Rate (min) | 0.65 V/µs (±15V) - supports clean amplification of fast transients in inverter gate driver monitoring or head unit audio pre-amplification stages. |
| Input Voltage Noise | 19 nV/√Hz at 10 Hz - minimizes contribution to total system noise floor in low-frequency sensor interfaces like thermistor or strain gauge amplifiers. |
| ESD Protection | >1000 V per MIL-STD-883 Method 3015 - provides inherent resilience against handling and assembly electrostatic events in production environments. |
Pinout & Package
Package: D (SOIC-8), 8-pin small-outline integrated circuit with standard 1.27 mm pitch; RoHS-compliant, moisture sensitivity level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives downstream circuitry; capable of ±30 mA output current and rail-to-rail swing within specified load conditions. |
| 2 | –IN A | Inverting input channel A - accepts feedback or inverted signal path; internally protected against phase reversal when driven below V–. |
| 3 | +IN A | Noninverting input channel A - high-impedance node (50 nA max bias current); supports direct connection to low-output-impedance sensors. |
| 4 | V– | Negative supply terminal - must be connected to lowest system potential (e.g., ground in single-supply or –15V in dual-supply). |
| 5 | +IN B | Noninverting input channel B - electrically isolated from channel A; enables independent dual-signal processing on one die. |
| 6 | –IN B | Inverting input channel B - shares same phase-reversal protection and input stage characteristics as pin 2. |
| 7 | OUT B | Amplifier B output - fully independent output stage; allows simultaneous driving of separate loads without crosstalk. |
| 8 | V+ | Positive supply terminal - connects to highest system potential (e.g., 5V or +15V); supplies both amplifiers from shared rail. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for continuous operation from –40°C to +125°C ambient, meeting automotive reliability and lifetime requirements for body electronics and powertrain-adjacent systems. |
| Rail-to-rail input (to V–) | Enables accurate amplification of signals referenced to ground in single-supply configurations - essential for shunt-based current sensing in BMS and DC/DC converters. |
| Phase-reversal protection | Prevents catastrophic output polarity flip during input overdrive or transient faults - eliminates need for external clamping diodes in safety-critical signal paths. |
| Low 300 µA max supply current | Reduces thermal load and power budget impact in always-on modules such as door control units or lighting ECUs with strict quiescent current limits. |
| High open-loop gain (6.5 V/µV) | Ensures <0.001% gain error in unity-gain buffer or high-precision instrumentation amplifier configurations, even with 10 kΩ load. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV9062-Q1 | Faster 10 MHz GBW, lower 0.3 pA bias current, but higher 560 µA supply current and only 105 dB CMRR. | Better for high-speed active filters; less suitable for ultra-low-power always-on BMS monitoring due to higher quiescent draw. | Select TLE2022AQDRQ1 when dc precision, low noise, and sub-300 µA supply current outweigh raw speed needs. |
| OPA2333-Q1 | Zero-drift architecture, 0.02 µV/°C drift, but limited 350 kHz GBW and no phase-reversal protection. | Ideal for microvolt-level sensor offsets; unsuitable for motor control transients or inputs that may go below V–. | Choose TLE2022AQDRQ1 where phase-reversal immunity and 2.8 MHz bandwidth are required alongside good dc accuracy. |
Compared with TLV9062-Q1 and OPA2333-Q1, the TLE2022AQDRQ1 uniquely balances automotive-grade temperature stability, phase-reversal protection, low-noise precision, and ultra-low quiescent current - making it optimal for dual-path signal conditioning in safety-aware, power-constrained automotive subsystems.

FAQ
What is the maximum operating temperature range for the TLE2022AQDRQ1?
The TLE2022AQDRQ1 is qualified per AEC-Q100 Grade 1 and operates continuously from –40°C to +125°C ambient temperature. This rating is validated across all electrical parameters in the datasheet, including input offset voltage, CMRR, and supply current, making it suitable for under-hood and powertrain-adjacent applications where thermal stress is extreme.
Does the TLE2022AQDRQ1 support single-supply operation at 5V?
Yes, the TLE2022AQDRQ1 is fully specified for 5V single-supply operation. At VCC+ = 5V and VCC– = 0V, it maintains 3.2 V common-mode input range to the positive rail, 0 V to the negative rail, 0.5 V/µs slew rate, and 1.7 MHz gain bandwidth - enabling reliable use in 5V automotive infotainment and body control modules.
How does phase-reversal protection work in the TLE2022AQDRQ1?
The TLE2022AQDRQ1 incorporates internal circuitry that prevents output polarity inversion when either input is driven below the negative supply rail (V–). Unlike standard op-amps that may latch or reverse output during such overdrive, the TLE2022AQDRQ1 maintains predictable behavior - eliminating risk of erroneous actuation in safety-critical feedback paths like motor current limiting or brake light control.
What is the typical input voltage noise density of the TLE2022AQDRQ1 at 1 kHz?
The TLE2022AQDRQ1 exhibits a typical input voltage noise density of 15 nV/√Hz at 1 kHz under ±15V supply conditions. This value is measured directly from the device's spectral noise profile and remains stable across temperature, supporting low-noise amplification in precision sensor interfaces such as thermocouple or RTD signal chains in automotive climate control systems.
Is the TLE2022AQDRQ1 pin-compatible with non-Q1 versions like TLE2022IDR?
No, the TLE2022AQDRQ1 is not pin-compatible with commercial-grade TLE2022IDR. While both use the SOIC-8 (D) package and share identical pin numbering and functions, the TLE2022AQDRQ1 undergoes additional automotive qualification testing (including AEC-Q100 stress screening, enhanced ESD robustness, and extended temperature characterization), and its datasheet specifies tighter parametric limits - particularly for offset voltage drift and CMRR over temperature.
