Product details
Overview
TLV9351QDBVRQ1 from Texas Instruments is a single-channel, AEC-Q100 Grade 1 qualified automotive operational amplifier with rail-to-rail output, 3.5MHz gain-bandwidth, ±60mA output drive, and MUX-friendly inputs enabling differential input voltage up to the full 40V supply rail. It delivers ±350µV offset, ±1.5µV/°C drift, 15nV/√Hz noise at 1kHz, and 20V/µs slew rate for precision current sensing and sensor signal conditioning in HEV/EV powertrain and ADAS subsystems.
For engineers reviewing the TLV9351QDBVRQ1 datasheet, TLV9351QDBVRQ1 pinout, TLV9351QDBVRQ1 application, or TLV9351QDBVRQ1 equivalent, key selection criteria include its 40V wide supply range (±2.25V to ±20V), robust EMI rejection (94dB at 5GHz), rail-to-rail output swing within 10mV of rails, low 600µA quiescent current, and operation across –40°C to 125°C ambient.
Technical Context
The TLV9351QDBVRQ1 employs a patented input architecture eliminating conventional back-to-back diode clamps, enabling true 40V differential input capability without signal distortion or settling delay-critical for multiplexed sensor front-ends. Its Class AB output stage supports ±60mA sourcing/sinking while maintaining rail-to-rail output swing under load.
This device integrates on-die EMI filtering optimized for automotive environments, delivering ≥71dB EMIRR from 400MHz to 5GHz, and features high open-loop gain (130dB typ), 110dB CMRR, and 20V/µs slew rate to preserve fidelity in fast transient detection circuits like motor phase current monitoring.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 3.5MHz - enables stable unity-gain operation up to 3.5MHz or closed-loop gain of 10 at 350kHz for sensor amplification. |
| Slew rate | 20V/µs - supports accurate reproduction of fast transients in motor control feedback loops and overcurrent detection. |
| Input offset voltage | ±350µV (typ) - ensures ≤0.35mV error in 100mV full-scale current-sense applications without trimming. |
| Supply voltage range | 4.5V to 40V (or ±2.25V to ±20V) - compatible with 12V/24V/42V automotive battery systems and isolated HV domains. |
| Output drive current | ±60mA - directly drives 67Ω loads (e.g., 50Ω + 17Ω trace) or multiple downstream comparators without buffering. |
| EMI rejection ratio | 94dB at 5GHz - suppresses interference from 5G/Wi-Fi 5/6 co-location in infotainment and ADAS ECUs. |

Pinout & Package
TLV9351QDBVRQ1 is packaged in a 5-pin SOT-23 (DBV) package measuring 2.9mm × 2.8mm, optimized for space-constrained automotive modules and thermally efficient PCB layout with exposed pad option (not applicable to DBV).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: OUT | Amplifier output | Delivers rail-to-rail voltage swing; capable of ±60mA continuous sourcing/sinking into resistive or capacitive loads. |
| 2: V– | Negative supply | Connects to lowest system potential (e.g., GND or negative rail); supports dual-supply (±2.25V) or single-supply (4.5V+) operation. |
| 3: IN+ | Noninverting input | High-impedance node (6TΩ || 1pF) accepting common-mode voltages from (V–) – 0.2V to (V+) – 2V. |
| 4: IN– | Inverting input | Same high-impedance specification as IN+; differential input range extends to full 40V, enabling comparator use. |
| 5: V+ | Positive supply | Accepts highest system potential (up to 40V); internal regulation ensures stable biasing across full supply range. |
Key Features
| Feature | Design Value |
|---|---|
| MUX-friendly inputs | Differential input voltage tolerance up to full 40V supply allows direct connection after analog multiplexers without external clamping or level-shifting. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM7332QMA/NOPB | Higher 24MHz GBW but higher 2.1mA IQ; no integrated EMI filtering; ±30V max supply. | Better for wideband active filters; less suitable for EMI-heavy infotainment zones or 42V HEV systems. | Choose LM7332QMA/NOPB when bandwidth >10MHz is required and EMI immunity is secondary. |
| TSV911QDBVRQ1 | Lower 8MHz GBW, 500µA IQ, but only 24V max supply; no MUX-friendly input architecture. | Cost-optimized for lower-voltage body electronics; lacks 40V differential input tolerance for multiplexed HV sensors. | Choose TSV911QDBVRQ1 for 12V-only applications where 3.5MHz bandwidth is excessive and cost is primary. |
Compared with LM7332QMA/NOPB and TSV911QDBVRQ1, TLV9351QDBVRQ1 uniquely balances 40V operation, MUX compatibility, and automotive-grade EMI immunity-making it optimal for next-generation HEV/EV powertrain and ADAS signal chains where supply voltage headroom and noise resilience are non-negotiable.

FAQ
What is the maximum differential input voltage supported by TLV9351QDBVRQ1?
TLV9351QDBVRQ1 supports a maximum differential input voltage of 40V-equal to its full supply voltage range. This enables direct use after analog multiplexers or as a comparator without external clamping diodes, unlike conventional op amps limited to ~0.7V differential input due to internal ESD diodes.
Does TLV9351QDBVRQ1 require external EMI filtering in automotive designs?
No-TLV9351QDBVRQ1 integrates on-die EMI filtering on both IN+ and IN– pins, achieving ≥90dB EMIRR at 2.4GHz and 94dB at 5GHz. This eliminates the need for external RC filters or ferrite beads in most automotive PCB layouts, reducing BOM count and board area in infotainment and ADAS modules.
Can TLV9351QDBVRQ1 operate from a single 5V supply?
Yes-TLV9351QDBVRQ1 operates from 4.5V to 40V single supply (or ±2.25V to ±20V dual supply). At 5V, it delivers rail-to-rail output swing down to 1mV from rails (no load) and maintains 3.5MHz GBW, making it suitable for low-voltage sensor interfaces in automotive body controllers.
What is the thermal resistance of TLV9351QDBVRQ1 in the DBV package?
In the 5-pin SOT-23 (DBV) package, TLV9351QDBVRQ1 has a junction-to-ambient thermal resistance (RθJA) of 187.4°C/W and junction-to-board resistance (RθJB) of 54.6°C/W. These values assume standard JEDEC 2-layer board conditions and confirm suitability for surface-mount placement in thermally constrained automotive modules.
Is TLV9351QDBVRQ1 qualified for AEC-Q100 Grade 0 applications?
No-TLV9351QDBVRQ1 is qualified to AEC-Q100 Grade 1 (–40°C to +125°C ambient), not Grade 0 (–40°C to +150°C). It meets all stress tests and reliability requirements for under-hood and powertrain applications within its specified temperature range, but is not rated for extreme high-temperature engine bay locations requiring Grade 0.
