Product details
Overview
TSV911AQDCKRQ1 from Texas Instruments is a single-channel automotive-grade rail-to-rail input/output operational amplifier optimized for AEC-Q100 Grade 1 (–40°C to +125°C), featuring 8 MHz gain bandwidth, 18 nV/√Hz input voltage noise at 1 kHz, 550 µA quiescent current, and ±1.85 mV maximum input offset voltage. It serves precision signal conditioning in low-side current sensing, ADAS sensor interfaces, and infotainment power supply monitoring.
For engineers reviewing the TSV911AQDCKRQ1 datasheet, TSV911AQDCKRQ1 pinout, TSV911AQDCKRQ1 application, or TSV911AQDCKRQ1 equivalent, key selection criteria include its SC70-5 package footprint, unity-gain stability, RFI-EMI rejection filter, no phase reversal under overdrive, and guaranteed performance across automotive temperature and supply ranges (2.5 V to 5.5 V).
Technical Context
The TSV911AQDCKRQ1 employs a complementary differential input stage-N-channel and P-channel pairs-to achieve rail-to-rail input operation extending 100 mV beyond both supply rails across 2.5 V–5.5 V supplies. Its class AB output stage delivers rail-to-rail swing within 20 mV of rails into 10 kΩ loads.
It integrates an RFI-EMI rejection filter, exhibits no phase reversal during overdrive, and recovers from saturation in 200 ns. The device is unity-gain stable and supports high-source-impedance sensor interfaces due to ultra-low 1 pA typical input bias current and low 0.5 µV/°C offset drift.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 8 MHz - enables stable closed-loop operation up to 100 kHz with G = 80, suitable for ADC driver and active filter stages. |
| Input Offset Voltage (max) | ±1.85 mV at TA = 25°C - ensures ≤1.85 mV error in precision DC-coupled amplification (e.g., shunt-based current sensing). |
| Quiescent Current | 550 µA per channel - allows battery-sensitive automotive modules (e.g., body control units) to maintain performance without excessive power draw. |
| Input Voltage Noise | 18 nV/√Hz at 1 kHz - supports low-noise amplification of microvolt-level sensor signals (e.g., thermopile, Hall-effect outputs). |
| Supply Voltage Range | 2.5 V to 5.5 V - compatible with 3.3 V and 5 V automotive domains, including post-regulated ECUs and infotainment SoC power rails. |
| Operating Temperature | –40°C to +125°C - qualified per AEC-Q100 Grade 1 for under-hood and cabin applications without derating. |
| ESD Rating (HBM) | ±4 kV - provides robustness against handling and system-level ESD events in vehicle assembly and service environments. |
Pinout & Package
TSV911AQDCKRQ1 is packaged in a 5-pin SC70 (DCK) package measuring 2.0 mm × 2.20 mm, optimized for space-constrained automotive PCBs and compatible with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: IN+ | Noninverting input | Accepts reference or sensor signal; rail-to-rail common-mode range (V– – 0.1 V to V+ + 0.1 V) enables direct connection to grounded sensors. |
| 2: V– | Negative supply / ground | Serves as return path for single-supply operation; must be connected to system ground or negative rail; not internally tied to substrate. |
| 3: IN– | Inverting input | Used for feedback network attachment; high impedance (1 pA bias) minimizes loading on high-Z sources like capacitive humidity sensors. |
| 4: OUT | Amplifier output | Delivers rail-to-rail swing (within 20 mV of rails into 10 kΩ); drives ADC inputs, comparator thresholds, or low-power analog switches directly. |
| 5: V+ | Positive supply | Accepts 2.5 V–5.5 V; internal regulation ensures stable biasing across supply transients common in automotive 12 V systems. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full dynamic range utilization in 3.3 V systems (e.g., OBC auxiliary supplies), eliminating level-shifting components in single-supply designs. |
| Integrated RFI-EMI rejection filter | Rejects >60 dB of 900 MHz–2.4 GHz interference (e.g., cellular, Bluetooth), critical for reliable operation near infotainment antennas or motor inverters. |
| No phase reversal under overdrive | Prevents latch-up or erroneous control signals when input exceeds common-mode range-essential for fault-tolerant ADAS sensor front-ends. |
| Low input bias current (1 pA typ) | Permits use with high-impedance pH electrodes, piezoresistive pressure sensors, and MEMS microphones without signal degradation. |
| Unity-gain stable | Eliminates need for external compensation; simplifies layout and reduces BOM count in gain-of-1 buffer and active filter configurations. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV931QDBVRQ1 | Lower GBP (1.5 MHz), higher IQ (120 µA), same SC70-5 package and AEC-Q100 Grade 1 rating. | Better suited for ultra-low-power wake-up circuits where bandwidth <2 MHz suffices. | Select when power budget is tighter than speed requirement; avoid for ADC drivers requiring >5 MHz fidelity. |
| TSZ121ILT | Higher precision (±150 µV max VOS), lower noise (12 nV/√Hz), but only industrial temp range (–40°C to +105°C), non-automotive qualified. | Applicable in non-safety-critical cabin modules where extended temperature is not mandated. | Choose only for cost-sensitive non-AEC-Q100 designs; not acceptable for powertrain or ADAS functions. |

FAQ
What is the maximum input offset voltage specification for TSV911AQDCKRQ1?
The maximum input offset voltage for TSV911AQDCKRQ1 is ±1.85 mV at TA = 25°C and VS = 5 V, as specified in the Electrical Characteristics table of the official datasheet (SBOSA18C, Rev C). This value increases to ±3 mV over the full operating temperature range (–40°C to +125°C), ensuring predictable DC error in automotive sensor interfaces.
Does TSV911AQDCKRQ1 support single-supply operation?
Yes, TSV911AQDCKRQ1 fully supports single-supply operation from 2.5 V to 5.5 V. Its rail-to-rail input extends 100 mV beyond both supply rails (V– – 0.1 V to V+ + 0.1 V), and its rail-to-rail output swings within 20 mV of either rail into 10 kΩ loads-enabling direct interfacing with 3.3 V microcontrollers and ADCs without level-shifting circuitry.
What package type is used for TSV911AQDCKRQ1?
TSV911AQDCKRQ1 uses the SC70-5 (DCK) package: a 5-pin surface-mount package measuring 2.0 mm × 2.20 mm. This compact footprint is explicitly listed in the Device Information table and Pin Configuration section of the datasheet, and is distinct from the SOT-23 (DBV) variant of the same family.
Is TSV911AQDCKRQ1 qualified for automotive applications?
Yes, TSV911AQDCKRQ1 is AEC-Q100 Grade 1 qualified (–40°C to +125°C ambient), with built-in ±4-kV HBM ESD protection and integrated RFI-EMI rejection filtering. Its design targets infotainment, ADAS, body electronics, and HEV/EV power systems-meeting stringent automotive reliability, thermal, and electromagnetic compatibility requirements.
What is the overload recovery time of TSV911AQDCKRQ1?
The overload recovery time of TSV911AQDCKRQ1 is 200 ns, as documented in Section 8.3.3 of the datasheet. This fast recovery enables reliable operation in transient-heavy environments such as motor control feedback loops and switching power supply monitoring, where rapid return from saturation is essential to prevent control instability.
