Product details
Overview
TLV9061SQDBVRQ1 from Texas Instruments is an AEC-Q100 Grade 1 qualified, single-channel, rail-to-rail input/output CMOS operational amplifier optimized for automotive applications. It delivers 10 MHz unity-gain bandwidth, ±0.3 mV input offset voltage, 10 nV/√Hz input voltage noise, 538 µA quiescent current, and operates from 1.8 V to 5.5 V supply. It is used in HEV/EV motor control current sensing and ADAS sensor signal conditioning.
For engineers reviewing the TLV9061SQDBVRQ1 datasheet, TLV9061SQDBVRQ1 pinout, TLV9061SQDBVRQ1 application, or TLV9061SQDBVRQ1 equivalent, this page provides verified technical context, pin-level design meaning, automotive-grade reliability data, and validated alternative options for low-voltage, high-precision signal amplification in safety-critical systems.
Technical Context
The TLV9061SQDBVRQ1 employs a CMOS input stage with 0.5 pA input bias current and resistive open-loop output impedance (100 Ω at 10 MHz), enabling stable operation into >100 pF capacitive loads without external compensation. Its unity-gain stability, internal RFI/EMI filtering, and no-phase-reversal behavior under overdrive support robust front-end amplification in noisy automotive environments.
Designed specifically for AEC-Q100 Grade 1 (–40°C to +125°C), it features HBM ESD rating of ±4000 V and CDM rating of ±1500 V. Functional safety documentation is available to support ISO 26262 ASIL-B system-level development, and its rail-to-rail I/O supports single-supply configurations down to 1.8 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Unity-gain bandwidth | 10 MHz - enables accurate amplification of signals up to ~1 MHz in closed-loop G = +1 configuration with adequate phase margin. |
| Input offset voltage | ±0.3 mV (typ) - ensures ≤0.6 mV total error in precision current-sensing circuits at room temperature. |
| Input voltage noise density | 10 nV/√Hz at 10 kHz - supports low-noise amplification of microvolt-level sensor outputs without significant SNR degradation. |
| Quiescent current | 538 µA per amplifier - allows battery-sensitive automotive modules (e.g., always-on ADAS sensors) to maintain performance with minimal power penalty. |
| Supply voltage range | 1.8 V to 5.5 V - compatible with modern automotive 3.3 V and 5 V domains, including post-regulated MCU subsystems. |
| CMRR | 80–103 dB (TA = –40°C to +125°C) - rejects common-mode interference from motor switching or power rail transients in body electronics. |
| Open-loop output impedance | 100 Ω (at 10 MHz) - simplifies stability with high-capacitance loads (e.g., long PCB traces or ADC input filters) without added series resistance. |
Pinout & Package
TLV9061SQDBVRQ1 is packaged in a 5-pin SOT-23 (DBV) footprint measuring 2.90 mm × 2.80 mm, suitable for space-constrained automotive PCB layouts and reflow-compatible assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT | Output | Amplified signal source; rail-to-rail swing supports full dynamic range utilization into 10 kΩ loads or higher. |
| 2 - V− | Negative supply / ground reference | Lowest potential node; accepts single-supply grounding or dual-rail negative rail; must be low-impedance for PSRR integrity. |
| 3 - IN+ | Noninverting input | High-impedance (CMOS) node; 0.5 pA bias current minimizes voltage drop across high-value sensor resistors. |
| 4 - IN− | Inverting input | High-impedance node; matched to IN+ for optimal common-mode rejection; sensitive to layout-induced parasitic coupling. |
| 5 - V+ | Positive supply | Highest potential node; supplies internal biasing; decoupling capacitor (0.1 µF ceramic) required within 2 mm for EMI immunity. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full-scale signal capture and drive in 1.8 V–5.5 V single-supply systems, eliminating level-shifting circuitry in low-voltage ADAS modules. |
| AEC-Q100 Grade 1 qualification | Validated operation from –40°C to +125°C ambient, meeting thermal requirements for engine bay, infotainment, and powertrain ECUs. |
| Internal RFI and EMI filter | Reduces susceptibility to GSM, LTE, and CAN bus noise-critical for reliable operation near wireless chargers or OBC inverters. |
| No phase reversal under overdrive | Prevents latch-up or erroneous control signals during transient overload (e.g., load dump or sensor short), improving functional safety compliance. |
| Resistive open-loop output impedance | Eliminates need for isolation resistors when driving ADC input capacitors or long traces, reducing BOM count and layout complexity. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA316QDBVRQ1 | Same AEC-Q100 Grade 1 rating, but lower 10 MHz GBW (same), higher 1.2 mV max offset, and 1.2 mA IQ vs 538 µA. | Better DC precision at cost of 2.2× higher quiescent current; less suitable for always-on battery-powered modules. | Select when ultra-low offset drift (<0.15 µV/°C) is prioritized over power; verify thermal derating at 125°C ambient. |
| TLV9001QDBVRQ1 | Lower 1 MHz GBW, 1.6 mV max offset, 60 µA IQ, and no internal EMI filter or no-phase-reversal guarantee. | Targeted at cost-sensitive, non-safety-critical body electronics; lacks functional safety documentation and EMI hardening. | Choose only for non-ASIL applications where bandwidth and noise are secondary; not recommended for ADAS or powertrain use. |
Compared with OPA316QDBVRQ1 and TLV9001QDBVRQ1, TLV9061SQDBVRQ1 uniquely balances 10 MHz bandwidth, sub-millivolt offset, automotive-grade ESD/EMI robustness, and <540 µA quiescent current-making it the optimal choice for ASIL-B-compliant, low-power, high-fidelity signal chains in modern vehicles.

FAQ
What is the maximum capacitive load the TLV9061SQDBVRQ1 can drive while maintaining stability?
The TLV9061SQDBVRQ1 is characterized for stable operation with ≥100 pF capacitive loads due to its resistive open-loop output impedance (~100 Ω). Unlike conventional op amps requiring external series resistance, TLV9061SQDBVRQ1 maintains ≥55° phase margin up to 300 pF in G = +1 configuration, enabling direct connection to ADC input capacitors or long PCB traces without compensation networks.
Does TLV9061SQDBVRQ1 support single-supply operation at 1.8 V?
Yes, TLV9061SQDBVRQ1 is fully specified for 1.8 V to 5.5 V supply operation. At 1.8 V, it retains rail-to-rail input/output swing, 10 MHz gain bandwidth, and 538 µA quiescent current. Input common-mode range extends from (V−) − 0.1 V to (V+) + 0.1 V, allowing direct interfacing with 1.8 V logic and sensors without level shifters.
Is TLV9061SQDBVRQ1 pin-compatible with any other Texas Instruments op amps?
No, TLV9061SQDBVRQ1 uses a standard 5-pin SOT-23 (DBV) pinout (OUT, V−, IN+, IN−, V+), but it is not pin-compatible with OPA316QDBVRQ1 (same package but different pin mapping) or TLV9001QDBVRQ1 (identical pinout but distinct AC/DC specs). Board redesign is required for substitution; verify pin functions using Table 7-1 in SBOS966H.
What functional safety documentation is available for TLV9061SQDBVRQ1?
Texas Instruments provides a Functional Safety FIT rate report, failure mode effects analysis (FMEA), and safety manual for TLV9061SQDBVRQ1-supporting ISO 26262 ASIL-B system-level development. These documents detail diagnostic coverage, safe failure fraction, and recommended diagnostic methods for use in automotive safety-critical applications.
How does the internal EMI filter in TLV9061SQDBVRQ1 improve system-level immunity?
The integrated RFI/EMI filter in TLV9061SQDBVRQ1 attenuates high-frequency interference (e.g., 800 MHz–2.5 GHz cellular, Bluetooth, or inverter switching noise) at the input stage, achieving >60 dB EMIRR+ rejection. This eliminates need for external RC filters in ADAS or infotainment designs, preserving signal integrity while reducing component count and board space.
