Product details
Overview
TLV9061QDCKRQ1 from Texas Instruments is an AEC-Q100 Grade 1 qualified single-channel rail-to-rail input/output CMOS operational amplifier optimized for automotive systems. 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 - enabling precision signal conditioning in infotainment, ADAS current sensing, and body electronics.
For engineers reviewing the TLV9061QDCKRQ1 datasheet, TLV9061QDCKRQ1 pinout, TLV9061QDCKRQ1 application, or TLV9061QDCKRQ1 equivalent, key selection considerations include its resistive open-loop output impedance (100 Ω at 10 MHz), functional safety documentation support, AEC-Q100 HBM Class 3A/CDM Class C6 ESD rating, and stable operation with ≥100 pF capacitive loads without external compensation.
Technical Context
The TLV9061QDCKRQ1 employs a CMOS input stage with ultra-low input bias current (0.5 pA) and integrates internal RFI/EMI filtering to suppress high-frequency interference in noisy automotive environments. Its unity-gain stable architecture and no-phase-reversal behavior under overdrive ensure robust performance in feedback-critical applications like current-sense amplification and sensor front-ends.
Designed specifically for low-voltage automotive operation, it maintains rail-to-rail input common-mode range (V– – 0.1 V to V+ + 0.1 V) and output swing (within 20 mV of rails at 5.5 V with 10 kΩ load), while delivering consistent 103 dB CMRR and 80 dB PSRR across –40°C to +125°C ambient temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Unity-gain bandwidth | 10 MHz - supports fast closed-loop response in active filters and ADC drivers up to ~1 MSPS sampling rate. |
| Input offset voltage | ±0.3 mV (typ) - enables accurate unidirectional current sensing down to ~10 mV sense voltage with <0.5% error. |
| Quiescent current | 538 µA - allows battery-sensitive modules (e.g., always-on ADAS sensors) to operate >10 years on coin-cell backup. |
| Supply voltage range | 1.8 V to 5.5 V - compatible with 3.3 V microcontrollers and 5 V legacy automotive domains without level-shifting. |
| Input voltage noise density | 10 nV/√Hz at 10 kHz - preserves SNR in wideband sensor interfaces (e.g., piezoelectric knock sensors). |
| Open-loop output impedance | 100 Ω (at 10 MHz) - simplifies stability with high-capacitance loads (e.g., long PCB traces to ADC inputs) without series resistor compensation. |
| CMRR | 103 dB (typ, 5.5 V, DC) - rejects common-mode transients in shunt-based current monitoring across battery voltage swings. |
Pinout & Package
TLV9061QDCKRQ1 is packaged in a 5-pin SC70 (DCK) package measuring 2.00 mm × 2.2 mm, suitable for space-constrained automotive modules requiring high thermal efficiency and reflow compatibility.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| +IN (Pin 1) | Noninverting input | Accepts analog signals up to V– – 0.1 V and V+ + 0.1 V; high-impedance node (0.5 pA bias) minimizes loading on resistive sensor bridges. |
| V– (Pin 2) | Negative supply | Reference for single-supply operation (e.g., ground in 3.3 V systems); supports true rail-to-rail input when tied to system GND. |
| –IN (Pin 3) | Inverting input | Configures standard op-amp topologies (inverting amp, transimpedance); matched to +IN for low offset drift. |
| OUT (Pin 4) | Amplifier output | Drives capacitive loads up to 100 pF directly; rail-to-rail swing (20 mV from rails) ensures full dynamic range into SAR ADC reference buffers. |
| V+ (Pin 5) | Positive supply | Accepts 1.8–5.5 V; internal ESD protection clamps to rails; decoupling capacitor required within 2 mm for EMI immunity. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Enables full-scale signal acquisition from 0 V to V+ in single-supply configurations - critical for low-voltage battery monitoring and LIN bus interface circuits. |
| Resistive open-loop output impedance | 100 Ω at 10 MHz eliminates need for external isolation resistors when driving long traces or ADC input capacitance (>100 pF), reducing BOM count and layout complexity. |
| Integrated RFI/EMI filter | Rejects GSM/Bluetooth band interference (800 MHz–2.4 GHz) without external RC networks - validated by EMIRR+ >100 dB at 900 MHz per Figure 8-31. |
| AEC-Q100 Grade 1 qualification | Guarantees operation from –40°C to +125°C ambient with HBM ±4000 V / CDM ±1500 V ESD robustness - meets automotive module-level reliability requirements. |
| No phase reversal under overdrive | Prevents latch-up or erroneous control signals during transient overvoltage events (e.g., load dump, ESD pulse), ensuring fail-safe behavior in safety-critical feedback loops. |

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, but lower 10 MHz GBW (same), higher 1.2 mV max offset, 1.3 mA IQ (2.4× higher). | Less suitable for ultra-low-power always-on modules; better for higher-drive applications needing 50 mA short-circuit current. | Select OPA316QDBVRQ1 only if higher output current or proven legacy qualification is required; TLV9061QDCKRQ1 preferred for power-constrained designs. |
| TSV911QDBVRQ1 | Lower 8 MHz GBW, 1.5 mV max offset, 155 µA IQ (lower), but no integrated RFI filter or functional safety documentation. | Not recommended for EMI-heavy ADAS or infotainment RF zones; lacks automotive functional safety design support. | Choose TSV911QDBVRQ1 only for cost-sensitive, non-safety-critical body electronics where EMI immunity is secondary. |
Compared with OPA316QDBVRQ1 and TSV911QDBVRQ1, TLV9061QDCKRQ1 uniquely balances ultra-low power (538 µA), precision (±0.3 mV offset), EMI resilience (integrated RFI filter), and functional safety readiness - making it optimal for next-generation automotive signal chains demanding both efficiency and robustness.

FAQ
What is the maximum capacitive load TLV9061QDCKRQ1 can drive without external compensation?
The TLV9061QDCKRQ1 can drive up to 100 pF capacitive load stably in unity-gain configuration due to its resistive open-loop output impedance (100 Ω). This eliminates the need for series isolation resistors typically required with conventional op-amps, simplifying layout in ADC driver and filter applications. Performance remains stable per Figure 8-23 and Figure 8-33 in the datasheet.
Does TLV9061QDCKRQ1 support single-supply operation at 3.3 V?
Yes, TLV9061QDCKRQ1 fully supports single-supply operation from 1.8 V to 5.5 V. At 3.3 V, it maintains rail-to-rail input (–0.1 V to 3.4 V) and output (within 20 mV of rails), enabling direct interfacing with 3.3 V microcontrollers and ADCs without level-shifting. Its 538 µA quiescent current also ensures minimal impact on system power budget.
Is TLV9061QDCKRQ1 pin-compatible with other members of the TLV906x-Q1 family?
No, TLV9061QDCKRQ1 is not pin-compatible with dual or quad variants (e.g., TLV9062-Q1 or TLV9064-Q1), which use SOIC, TSSOP, or VSSOP packages with different pin counts and assignments. However, the TLV9061QDCKRQ1 shares identical electrical specifications and functional behavior with TLV9061-Q1 in SOT-23 (DBV) packaging - only the physical footprint differs.
What functional safety documentation is available for TLV9061QDCKRQ1?
Texas Instruments provides functional safety documentation for TLV9061QDCKRQ1 including Failure Modes Effects and Diagnostic Analysis (FMEDA) reports, Safety Manual, and ISO 26262 ASIL-ready evidence - all accessible via TI's functional safety portal. These materials support system-level FMEDA and safety case development for ASIL-B and ASIL-C automotive applications.
How does the internal RFI/EMI filter in TLV9061QDCKRQ1 improve system-level EMC performance?
The integrated RFI/EMI filter in TLV9061QDCKRQ1 provides >100 dB rejection at 900 MHz (per Figure 8-31), suppressing cellular, Bluetooth, and keyless entry interference before it reaches the amplifier core. This reduces or eliminates the need for external ferrite beads or RC filters, lowering bill-of-materials cost and PCB area while improving consistency across production units in high-noise automotive environments.
