Product details
Overview
TLE2022QDRQ1 from Texas Instruments is a dual-channel, automotive-grade precision operational amplifier designed for low-level signal conditioning in single- or split-supply configurations. It delivers 2.8 MHz unity-gain bandwidth, 0.65 V/µs slew rate (±15V), 100 µV max input offset voltage, and operates across –40°C to +125°C - enabling use in battery management systems and motor control feedback loops.
For engineers reviewing the TLE2022QDRQ1 datasheet, TLE2022QDRQ1 pinout, TLE2022QDRQ1 application, or TLE2022QDRQ1 equivalent, key selection criteria include its AEC-Q100 qualification, rail-to-rail input capability (to negative rail), phase-reversal protection, and stable 300 µA supply current over temperature.
Technical Context
The TLE2022QDRQ1 uses a proprietary Texas Instruments bipolar process optimized for precision and stability, integrating bias circuitry that minimizes drift of offset voltage (±2 µV/°C) and supply current over time and temperature. Its architecture supports both single-supply (5V) and dual-supply (±15V) operation without performance degradation.
It features phase-reversal protection to prevent output inversion when inputs fall below the negative supply rail, and offers common-mode input range extending to the negative rail - critical for accurate sensing in grounded-referenced automotive sensor interfaces and current-shunt amplifiers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Dual - enables compact two-stage filtering or differential pair amplification in space-constrained ECUs. |
| Supply Voltage | ±2V to ±20V dual or 4V to 40V single - supports direct integration with 5V microcontrollers and 12V/24V vehicle power domains. |
| Unity-Gain Bandwidth | 2.8 MHz (±15V) - sufficient for closed-loop control in DC/DC converters and motor phase current monitoring up to ~200 kHz. |
| Slew Rate | 0.65 V/µs (±15V), 0.5 V/µs (5V) - ensures faithful reproduction of fast transients in battery cell voltage sampling. |
| Input Offset Voltage | ±150 µV (max, 25°C), ±700 µV (max, –40°C to +125°C) - enables sub-mV accuracy in shunt-based current measurement. |
| Supply Current | 550–700 µA total (dual channel, ±15V), 450–600 µA (5V) - suitable for always-on modules with strict quiescent power budgets. |
| CMRR | 95–106 dB (±15V), 85–100 dB (5V) - rejects noise from shared ground paths in high-noise powertrain environments. |
Pinout & Package

| 3 | +IN A | Noninverting input channel A - accepts low-side current-sense voltage or thermistor divider output. |
| 4 | V– | Negative supply - tied to system ground in single-supply mode; enables true rail-to-rail input operation. |
| 5 | +IN B | Noninverting input channel B - used for second independent signal path (e.g., temperature compensation reference). |
| 6 | –IN B | Inverting input channel B - supports differential configuration with channel A or independent sensor interface. |

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 supply current (560 µA), but higher offset (±1.6 mV max) and no phase-reversal protection. | Better for high-speed control loops; unsuitable where input faults below V– may occur. | Choose TLV9062-Q1 only if speed outweighs fault tolerance and DC accuracy requirements. |
| OPA2333-Q1 | Zero-drift architecture, lower offset (±2 µV), but lower bandwidth (350 kHz) and higher supply current (85 µA per channel). | Ideal for ultra-precision DC sensing; inadequate for >100 kHz feedback or motor control. | Select OPA2333-Q1 when long-term offset drift is critical and bandwidth demand is <50 kHz. |
Compared with TLV9062-Q1 and OPA2333-Q1, the TLE2022QDRQ1 uniquely balances AEC-Q100-compliant precision, phase-reversal immunity, and 2.8 MHz bandwidth - making it optimal for safety-critical, mixed-signal automotive subsystems requiring both accuracy and robustness.

FAQ
What is the maximum operating temperature range for the TLE2022QDRQ1?
The TLE2022QDRQ1 is qualified per AEC-Q100 Grade 1 and operates across –40°C to +125°C ambient temperature. This rating is validated for continuous operation in under-hood and battery-pack environments, with electrical characteristics fully specified across this full range in the datasheet's Recommended Operating Conditions table.
Does the TLE2022QDRQ1 support single-supply operation?
Yes, the TLE2022QDRQ1 supports single-supply operation from 4V to 40V. At 5V supply, it maintains rail-to-rail input capability down to the negative rail (0 V), delivers 4.3 V output swing, and draws 450–600 µA total supply current - making it suitable for direct interface with 5V microcontrollers and sensors.
What is the purpose of phase-reversal protection in the TLE2022QDRQ1?
Phase-reversal protection in the TLE2022QDRQ1 prevents unintended output polarity inversion when either input falls below the negative supply rail (e.g., due to ESD or wiring fault). This feature avoids erroneous control signals in safety-critical applications like BMS and EPS, eliminating the need for external clamping diodes.
How does the TLE2022QDRQ1 compare to the TLE2022A-Q1 variant?
The TLE2022QDRQ1 is the standard-grade version with ±150 µV max input offset voltage (25°C); the TLE2022A-Q1 offers improved dc specs - ±120 µV max offset and tighter drift (±2 µV/°C). Both share identical pinout, package, bandwidth, and AEC-Q100 qualification - select TLE2022A-Q1 only when sub-100 µV offset is mandatory.
Is the TLE2022QDRQ1 pin-compatible with legacy TLE2022 devices?
Yes, the TLE2022QDRQ1 uses the same SOIC-8 (D) package and identical pinout as non-automotive TLE2022 variants. However, it is not a drop-in replacement for non-Q1 parts in automotive designs due to differences in qualification testing, lot traceability, and failure-in-time (FIT) reporting - only TLE2022QDRQ1 meets AEC-Q100 requirements.
