Product details
Overview
TLV9361QDBVRQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive-qualified single-channel rail-to-rail output operational amplifier, delivering ±400 µV offset voltage, 10.6 MHz gain-bandwidth product, 25 V/µs slew rate, and operation across ±2.25 V to ±20 V (or 4.5 V to 40 V) supplies. It serves as a precision signal-conditioning amplifier in high-voltage analog front-ends for digital cockpit processing units.
For engineers reviewing the TLV9361QDBVRQ1 datasheet, TLV9361QDBVRQ1 pinout, TLV9361QDBVRQ1 application, or TLV9361QDBVRQ1 equivalent, key selection criteria include its 125°C operating temperature range, low 6 nV/√Hz broadband noise, robust EMIRR performance up to 91 dB at 5 GHz, and validated suitability for eCall and active noise cancellation circuits.
Technical Context
The TLV9361QDBVRQ1 employs a P-channel input stage with slew boost architecture to achieve high-speed, low-noise performance while maintaining rail-to-rail output swing and strong DC accuracy. Its internal thermal protection activates above 170°C junction temperature, preventing permanent damage during sustained overload conditions.
It features integrated EMI filtering on both inputs, enabling stable operation in electrically noisy automotive environments-particularly critical for applications near 2.4 GHz (Bluetooth/Wi-Fi) and 5 GHz (802.11a/n) bands where measured EMIRR exceeds 70 dB and 91 dB respectively.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 4.5 V to 40 V (±2.25 V to ±20 V): supports direct connection to 12 V/24 V automotive battery rails without external regulation |
| Gain-Bandwidth Product | 10.6 MHz: enables stable closed-loop operation up to ~1 MHz with G = +10, suitable for sensor signal amplification and filter stages |
| Slew Rate | 25 V/µs: ensures faithful reproduction of fast transients in audio and control loop signals without distortion |
| Input Offset Voltage | ±0.4 mV (max), ±400 µV (typ): reduces DC error in precision current sensing and bridge amplifier configurations |
| Input Voltage Noise | 6 nV/√Hz (broadband): minimizes contribution to system noise floor in low-level sensor interfaces |
| Common-Mode Rejection | 110 dB: maintains accuracy in presence of large common-mode disturbances such as ignition noise or load dump spikes |
| Output Drive Current | ±60 mA: drives low-impedance loads including 2 kΩ DAC buffers or active filter feedback networks |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA192QDGKRQ1 | Higher precision (±25 µV offset), lower noise (5.5 nV/√Hz), but higher IQ (1 mA vs 2.6 mA) and narrower supply (4.5 V–36 V) | Better suited for ultra-low-error current sensing; less optimal for cost-sensitive, high-output-drive needs | Select when offset drift (<±0.2 µV/°C) and long-term stability outweigh drive strength and price sensitivity |
| LM7332QMA/NOPB | Wider supply (±16 V), higher output current (±100 mA), but no AEC-Q100 qualification and higher noise (14 nV/√Hz) | Acceptable for industrial-grade infotainment prototypes; not certified for production automotive deployment | Select only for non-safety-critical development or legacy platform reuse where AEC-Q100 is not mandated |
Compared with OPA192QDGKRQ1 and LM7332QMA/NOPB, TLV9361QDBVRQ1 delivers the best balance of automotive qualification, 40 V operation, ±60 mA drive, and cost efficiency-making it the preferred choice for volume production in digital cockpit and telematics ECUs where robustness and BOM cost are jointly prioritized.

FAQ
What is the maximum supply voltage rating for TLV9361QDBVRQ1?
The TLV9361QDBVRQ1 has an absolute maximum supply voltage of 42 V (V+ to V−), with recommended operation from 4.5 V to 40 V. This allows direct use with 12 V and 24 V automotive battery systems, including transient conditions up to 40 V, without external regulation. Operation beyond 40 V risks exceeding safe operating area limits and triggering thermal shutdown.
Does TLV9361QDBVRQ1 support single-supply operation?
Yes, TLV9361QDBVRQ1 fully supports single-supply operation from 4.5 V to 40 V. Its rail-to-rail output stage delivers output swing within 100 mV of both rails under load, and its input common-mode range extends to within 2 V of V+, enabling direct interfacing with microcontroller ADC references or unipolar sensor outputs without level-shifting circuitry.
What is the guaranteed offset voltage drift specification for TLV9361QDBVRQ1 over temperature?
The TLV9361QDBVRQ1 guarantees ±1.25 µV/°C maximum input offset voltage drift across the full AEC-Q100 Grade 1 temperature range of –40°C to +125°C. This value is specified in the Electrical Characteristics table (Section 5.7) and verified across production lots, ensuring predictable DC error accumulation in precision amplification stages over vehicle lifetime.
Is TLV9361QDBVRQ1 pin-compatible with other members of the TLV936x-Q1 family?
No, TLV9361QDBVRQ1 is not pin-compatible with TLV9362-Q1 or TLV9364-Q1 due to differing channel counts and package footprints. The TLV9361QDBVRQ1 uses a 5-pin SOT-23 (DBV) package, whereas dual-channel and quad-channel variants require 8-pin SOIC/VSSOP/TSSOP and 14-pin SOIC/TSSOP packages respectively-requiring PCB layout changes for substitution.
How does the EMIRR performance of TLV9361QDBVRQ1 benefit automotive designs?
The TLV9361QDBVRQ1 achieves ≥70 dB EMIRR at 2.4 GHz and ≥91 dB at 5 GHz, directly mitigating interference from Bluetooth, Wi-Fi, and LTE radios co-located on modern automotive PCBs. This eliminates need for external ferrite beads or shielding in many signal-chain positions, simplifying layout and improving long-term reliability in electrically dense cockpit modules.
