Product details
Overview
TLE2022AQDRG4Q1 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 gain bandwidth, 0.65 V/µs slew rate, ±15V or 5V single-supply operation, 100 µV max input offset voltage, and operates across –40°C to +125°C for body electronics and battery management signal conditioning.
For engineers reviewing the TLE2022AQDRG4Q1 datasheet, TLE2022AQDRG4Q1 pinout, TLE2022AQDRG4Q1 application, or TLE2022AQDRG4Q1 equivalent, key selection criteria include rail-to-rail input capability (to negative rail), phase-reversal protection, low 700 µA max supply current over temperature, and A-suffix enhanced DC accuracy for sensor front-ends in safety-critical automotive systems.
Technical Context
The TLE2022AQDRG4Q1 uses a proprietary Texas Instruments bipolar process with integrated bias circuitry to stabilize parameters across time and temperature. Its architecture supports both single-supply (5V) and split-supply (±15V) configurations while maintaining precision performance - including common-mode input range extending to the negative rail and phase-reversal protection that prevents output inversion when inputs go below VCC–.
It features dual independent amplifiers sharing one die, each with matched AC/DC characteristics: typical open-loop gain of 4 V/µV (132 dB), CMRR ≥97 dB, PSRR ≥103 dB, and input noise density of 19 nV/√Hz at 10 Hz under ±15V operation - enabling high-fidelity amplification of low-level analog signals in noisy automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Dual independent op-amps on one die - enables compact dual-signal conditioning without inter-channel crosstalk penalties. |
| Supply Voltage | Specified for ±15V or 5V single-supply operation - supports legacy industrial rails and modern low-voltage automotive domains. |
| Input Offset Voltage | ≤120 µV (max at 25°C), ≤450 µV (max over –40°C to +125°C) - ensures minimal DC error in precision sensor interfaces like current shunt amplifiers. |
| Gain Bandwidth | 2.8 MHz (typical, ±15V) - supports stable closed-loop gain up to ~28 at unity-gain stability margin for anti-aliasing or active filtering. |
| Slew Rate | 0.65 V/µs (min, ±15V) - enables faithful reproduction of signals up to ~100 kHz full-power sine wave without distortion. |
| Common-Mode Range | Extends to negative rail (VCC–) - allows direct interfacing with ground-referenced sensors in single-supply systems without level-shifting. |
| Phase-Reversal Protection | Integrated circuitry prevents output polarity flip when input falls below VCC– - eliminates risk of uncontrolled actuator behavior in fault conditions. |
Pinout & Package
Package: D (SOIC-8), 8-pin small-outline integrated circuit with standard JEDEC MO-153 footprint and 1.27 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives external load or next stage; capable of ±30 mA output current. |
| 2 | –IN A | Inverting input for channel A - forms feedback node in inverting configurations; accepts signals down to VCC–. |
| 3 | +IN A | Noninverting input for channel A - used in noninverting buffers or difference amplifiers; includes phase-reversal protection. |
| 4 | VCC– | Negative power supply terminal - reference for all internal biasing; must be connected even in single-supply use (e.g., tied to GND). |
| 5 | +IN B | Noninverting input for channel B - electrically isolated from channel A; supports independent dual-signal paths. |
| 6 | –IN B | Inverting input for channel B - matches channel A specs; enables matched dual instrumentation amplifier topologies. |
| 7 | OUT B | Amplifier B output - fully independent output stage; shares thermal and supply coupling but no signal path with OUT A. |
| 8 | VCC+ | Positive power supply terminal - supplies both amplifiers; supports up to 20 V absolute max rating. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for –40°C to +125°C ambient operation - meets automotive reliability and lifetime requirements without derating. |
| Phase-reversal protection | Prevents output inversion during input faults below VCC– - critical for fail-safe behavior in motor control or BMS monitoring circuits. |
| Low input bias current (≤70 nA) | Minimizes voltage error across high-impedance sources like thermistors or piezoelectric sensors. |
| Stable supply current over temperature | ICC remains ≤700 µA across full operating range - simplifies thermal design and power budgeting in sealed ECUs. |
| Offset voltage drift ≤±2 µV/°C | Ensures long-term calibration stability in battery voltage monitors or cabin temperature sensing over vehicle lifetime. |

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 | Rail-to-rail I/O, lower 500 µA supply current, but only 1.5 MHz GBW and 100 µV offset (typical, not max); CMOS process. | Better for ultra-low-power always-on nodes; less suitable for high-speed current sensing or wide-bandwidth filtering. | Select TLV9062-Q1 when power budget is tighter than speed or DC accuracy requirements. |
| OPA2333-Q1 | Zero-drift architecture, 2 µV max offset, but 350 kHz GBW and higher 17 µV/√Hz noise; chopper-stabilized design. | Ideal for microvolt-level DC measurements (e.g., strain gauges), but insufficient slew rate for dynamic BMS events. | Choose OPA2333-Q1 only for static or near-DC sensor signals where offset drift dominates noise concerns. |
Compared with TLV9062-Q1 and OPA2333-Q1, the TLE2022AQDRG4Q1 uniquely balances 2.8 MHz bandwidth, sub-500 µV over-temperature offset, and phase-reversal protection - making it optimal for automotive analog signal chains requiring simultaneous speed, precision, and fault resilience.

FAQ
What is the maximum operating temperature range for the TLE2022AQDRG4Q1?
The TLE2022AQDRG4Q1 is AEC-Q100 Grade 1 qualified and specified to operate continuously from –40°C to +125°C ambient temperature. This rating applies to the full device - including input offset voltage, supply current, and gain bandwidth - and is validated per automotive reliability standards for engine bay and under-hood applications.
Does the TLE2022AQDRG4Q1 support single-supply operation?
Yes, the TLE2022AQDRG4Q1 supports true single-supply operation at 5V (VCC+ = 5V, VCC– = 0V). Its common-mode input range extends to the negative rail (0V), and output swings to within 0.7V of either rail under 10kΩ load - enabling direct interfacing with microcontrollers and ADCs in 5V automotive domains without level-shifting circuitry.
What does "phase-reversal protection" mean for the TLE2022AQDRG4Q1?
Phase-reversal protection in the TLE2022AQDRG4Q1 prevents the output from inverting polarity when either input is driven below the negative supply rail (VCC–). This eliminates erroneous actuation in safety-critical circuits - such as motor drivers or solenoid controllers - during ground-bounce transients or sensor disconnect faults, ensuring predictable failure modes.
How does the TLE2022AQDRG4Q1 differ from the non-A-suffix TLE2022-Q1?
The TLE2022AQDRG4Q1 is the A-suffix variant, featuring improved DC specifications versus the base TLE2022-Q1: maximum input offset voltage is reduced from ±500 µV to ±300 µV (25°C) and ±450 µV (–40°C to +125°C), and input offset drift is tightened to ±2 µV/°C - making it preferred for high-accuracy automotive sensor signal chains where long-term calibration stability is required.
Is the TLE2022AQDRG4Q1 pin-compatible with other devices in the TLE202x-Q1 family?
Yes, the TLE2022AQDRG4Q1 shares the same D (SOIC-8) package and pinout as the TLE2022-Q1, TLE2021-Q1, and TLE2021A-Q1 - enabling drop-in replacement within dual-channel layouts. However, it is not pin-compatible with the quad-channel TLE2024-Q1 (DW-16 package), nor with single-channel variants when board space or channel count differs.
