Product details
Overview
OPA2192QDGKRQ1 from Texas Instruments is a dual-channel, 36-V, rail-to-rail input/output precision operational amplifier with e-trim™ technology, ±5 µV typical offset voltage, ±0.2 µV/°C drift, 10 MHz bandwidth, and 20 V/µs slew rate-designed for high-accuracy current sensing in automotive traction inverters.
For engineers reviewing the OPA2192QDGKRQ1 datasheet, OPA2192QDGKRQ1 pinout, OPA2192QDGKRQ1 application, or OPA2192QDGKRQ1 equivalent, key selection criteria include ultra-low offset stability over temperature (–40°C to +125°C), EMI-filtered inputs for noisy powertrain environments, and robust capacitive-load drive capability up to 1 nF without external compensation.
Technical Context
The OPA2192QDGKRQ1 implements e-trim™ package-level trimming after plastic molding to minimize input transistor mismatch and package-induced offset errors-enabling stable dc precision across automotive temperature extremes. Its dual-channel architecture supports independent signal conditioning paths with 150 dB dc crosstalk rejection.
It features differential input voltage range extended to the supply rails, high output current (±65 mA), and thermal protection at 140°C-making it suitable for high-voltage industrial and automotive subsystems where reliability under transient overload and wide supply variation (±2.25 V to ±18 V) is critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Offset Voltage | ±5 µV typical - enables sub-0.01% error in 100-mV shunt-based current sensing at room temperature |
| Offset Drift | ±0.2 µV/°C typical - ensures <±1 µV total drift over –40°C to +125°C operating range |
| Bandwidth | 10 MHz - supports fast closed-loop response in motor phase current feedback loops |
| Slew Rate | 20 V/µs - maintains fidelity of high-slew transients in inverter gate driver monitoring |
| Supply Range | ±2.25 V to ±18 V (4.5 V to 36 V) - compatible with 12-V and 24-V automotive battery systems |
| Input Bias Current | ±5 pA typical - minimizes voltage error in high-impedance sensor interfaces (e.g., RTD, thermocouple) |
| Capacitive Load Drive | 1 nF - allows direct connection to long PCB traces or EMI filter networks without instability |
Pinout & Package
OPA2192QDGKRQ1 is housed in an 8-pin VSSOP package (3.00 mm × 3.00 mm body size) with exposed pad for thermal performance in automotive modules.
| Pin/Terminal | Circuit Role | Design Meaning |

| –IN A (Pin 2) | Inverting input, channel A | Feedback node for closed-loop gain configuration; accepts rail-to-rail common-mode input |
| OUT A (Pin 1) | Output, channel A | Capable of ±65 mA sink/source; drives 10-kΩ load within 15 mV of rails |
| +IN B (Pin 5) | Noninverting input, channel B | Independent second channel for dual-axis sensing or redundancy |
| –IN B (Pin 6) | Inverting input, channel B | Separate feedback path; no crosstalk coupling above 130 dB at 100 kHz |
| OUT B (Pin 7) | Output, channel B | Matched dynamic performance to OUT A; supports parallel output configurations |
| V+ (Pin 8) | Positive supply | Highest potential rail; must be decoupled locally with ≥100 nF ceramic capacitor |
| V– (Pin 4) | Negative supply | Lowest potential rail; referenced to system ground or negative battery terminal |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2189QDGKRQ1 | Lower offset drift (±0.005 µV/°C), higher cost, same VSSOP-8 package | Better suited for ultra-stable reference buffers in ADAS domain controllers | Select when drift-critical calibration intervals exceed 10 years or ambient range extends beyond +125°C junction |
| LT6018IMS8#PBF | Wider supply (4.5 V to 50 V), higher quiescent current (1.9 mA), MSOP-8 package | Preferred for industrial 48-V systems requiring extended overvoltage tolerance | Choose when operating above 36-V rail or needing enhanced latch-up immunity in harsh ESD environments |
Compared with OPA2192QDGKRQ1, the OPA2189QDGKRQ1 offers superior long-term drift stability at higher cost, while the LT6018IMS8#PBF trades lower power for wider supply range and higher ruggedness-neither is pin-compatible, but both support similar high-precision automotive signal chains.

FAQ
What is the maximum operating temperature for OPA2192QDGKRQ1?
The OPA2192QDGKRQ1 is qualified for continuous operation from –40°C to +125°C ambient temperature (AEC-Q100 Grade 1). Its internal thermal protection activates at 140°C junction temperature, providing safeguard against sustained overload conditions. This makes OPA2192QDGKRQ1 suitable for under-hood automotive applications where ambient temperatures exceed 105°C.
Does OPA2192QDGKRQ1 support single-supply operation?
Yes, OPA2192QDGKRQ1 supports true single-supply operation from 4.5 V to 36 V. Its rail-to-rail input and output stages allow common-mode voltage range from (V–) – 0.1 V to (V+) + 0.1 V and output swing within 15 mV of either rail under light load-enabling direct interfacing with ADCs and microcontrollers in 3.3-V or 5-V logic domains powered from the same supply.
What is the input offset voltage specification for OPA2192QDGKRQ1 over temperature?
Per the SBOS850 datasheet, OPA2192QDGKRQ1 has a maximum input offset voltage of ±75 µV over the full –40°C to +125°C operating range. At 25°C, typical VOS is ±5 µV, with ±10 µV maximum. This tight distribution is achieved via e-trim™ technology and is validated across production lots-critical for minimizing calibration overhead in production test.
Can OPA2192QDGKRQ1 drive heavy capacitive loads without oscillation?
Yes, OPA2192QDGKRQ1 is characterized to drive up to 1 nF capacitive loads stably, as confirmed in Figure 30 and Figure 31 of the SBOS850 datasheet. Its robust phase margin under capacitive loading eliminates need for external isolation resistors in many EMI filter designs-reducing component count and board space in automotive power modules where layout constraints are stringent.
Is OPA2192QDGKRQ1 pin-compatible with other dual op amps in VSSOP-8?
No, OPA2192QDGKRQ1 uses a proprietary pinout optimized for dual-channel independence and thermal symmetry-not pin-compatible with generic dual op amps like LM358 or TLV2372. Pin 1 is OUT A (not NC), Pin 5 is +IN B (not NC), and Pins 1/5/7 are active-requiring dedicated PCB layout. Migration requires schematic and layout revision.
