Product details
Overview
TLV9361QDCKRQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive-qualified, single-channel rail-to-rail output operational amplifier with 10.6 MHz gain-bandwidth, 25 V/µs slew rate, ±400 µV max input offset voltage, and operation from 4.5 V to 40 V supply. It delivers ±60 mA output current and supports digital cockpit processing, telematics control units, and eCall systems.
For engineers reviewing the TLV9361QDCKRQ1 datasheet, TLV9361QDCKRQ1 pinout, TLV9361QDCKRQ1 application, or TLV9361QDCKRQ1 equivalent, key selection criteria include its 125°C operating temperature range, SC70-5 package footprint, low 2.6 mA quiescent current per amplifier, and robust EMIRR performance up to 91 dB at 5 GHz - critical for high-noise automotive signal conditioning.
Technical Context
The TLV9361QDCKRQ1 implements a P-channel input stage with slew boost architecture to achieve 25 V/µs slew rate while maintaining unity-gain stability and 10.6 MHz bandwidth. Its input stage supports rail-to-rail common-mode range (V– to V+ – 2 V) and exhibits ±10 pA bias current with 6 nV/√Hz broadband input voltage noise density.
EMI rejection is integrated via on-die filtering, delivering ≥50 dB EMIRR from 400 MHz to 6 GHz - validated per TI's standardized test methodology - and thermal protection activates above 170°C junction temperature to prevent permanent damage during sustained overload conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 10.6 MHz - enables stable closed-loop operation up to 100 kHz with G = 100, suitable for active filter and sensor signal amplification in automotive ECUs. |
| Slew rate | 25 V/µs - supports fast transient response in motor control feedback loops and audio driver stages without distortion. |
| Input offset voltage | ±400 µV (max) - ensures ≤0.4 mV error in 10 V full-scale measurement paths, critical for precision battery monitoring and current sensing. |
| Supply voltage range | 4.5 V to 40 V - accommodates 12 V and 24 V automotive battery rails including cold-crank (4.5 V) and load-dump (40 V) transients. |
| Operating temperature | –40°C to +125°C - meets AEC-Q100 Grade 1 requirements for under-hood and infotainment module deployment. |
| Output current | ±60 mA - drives 2 kΩ loads to rail with <400 mV headroom at 40 V supply, enabling direct interface with ADC drivers and analog multiplexers. |
| EMIRR @ 5 GHz | 91 dB - suppresses interference from 5 GHz Wi-Fi/802.11a bands in connected vehicle modules without external shielding. |
Pinout & Package
TLV9361QDCKRQ1 uses the SC70-5 (DCK) package: 2.0 mm × 2.1 mm, 0.65 mm pitch, 5-pin surface-mount outline with exposed pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN+) | Non-inverting input | Accepts signals from V– to (V+) – 2 V; supports rail-to-rail input common-mode range for single-supply sensor interfaces. |
| 2 (V–) | Negative power supply | Reference node for dual-supply operation or ground in single-supply configurations; must be decoupled locally. |
| 3 (IN–) | Inverting input | High-impedance node (6 TΩ || 1 pF) for feedback networks; matched to IN+ for minimal input offset drift. |
| 4 (OUT) | Amplifier output | Rail-to-rail capable with ±60 mA drive; requires 20 pF capacitive load stability per datasheet Figure 5-28. |
| 5 (V+) | Positive power supply | Supports up to 40 V; internal ESD protection clamps to rails; requires 100 nF ceramic decoupling adjacent to pin. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use across –40°C to +125°C ambient, including HBM ±2 kV and CDM ±1.5 kV ESD robustness. |
| Rail-to-rail output swing | Delivers <100 mV headroom to rails at 40 V supply and 10 kΩ load - enables full dynamic range utilization in 12-bit+ SAR ADC front-ends. |
| Low input voltage noise density | 6 nV/√Hz broadband (10 kHz) - minimizes contribution to total system noise in high-gain sensor amplifiers (e.g., thermocouple, strain gauge). |
| High common-mode rejection | 110 dB (typ) at DC - rejects battery rail fluctuations and ground bounce in differential measurement circuits. |
| Integrated EMI filtering | EMIRR ≥70 dB at 2.4 GHz and ≥91 dB at 5 GHz - eliminates need for external RF chokes or ferrite beads in compact infotainment PCB layouts. |
| Thermal shutdown protection | Activates at >170°C junction temperature and forces output into high-Z state - prevents latch-up or parametric shift during sustained overloads. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA192QDGKRQ1 | Lower offset (±5 µV), higher cost, 10 MHz GBW, same SC70-5 package | Better suited for precision current sensing where offset error dominates; less optimized for cost-sensitive audio buffering | Select TLV9361QDCKRQ1 when BOM cost targets require sub-$0.50 op amps without sacrificing 125°C operation or EMI immunity. |
| LM7321QMF/NOPB | Higher quiescent current (1.25 mA vs 2.6 mA), 20 MHz GBW, SOIC-8 only - no SC70 option | Requires PCB redesign for package change; lacks integrated EMI filtering and AEC-Q100 Grade 1 validation at 125°C | Choose TLV9361QDCKRQ1 for new designs needing SC70-5 footprint, guaranteed 125°C operation, and certified EMI resilience in compact modules. |
Compared with OPA192QDGKRQ1 and LM7321QMF/NOPB, TLV9361QDCKRQ1 uniquely balances AEC-Q100 Grade 1 compliance, SC70-5 size, 91 dB 5 GHz EMIRR, and sub-$0.40 pricing - making it optimal for space-constrained, noise-prone automotive signal chains where cost and robustness are co-prioritized.

FAQ
What is the maximum supply voltage rating for TLV9361QDCKRQ1?
The TLV9361QDCKRQ1 has an absolute maximum supply voltage of 42 V, with recommended operation from 4.5 V to 40 V. This allows reliable use across 12 V and 24 V automotive battery systems, including transient conditions like cold-crank (4.5 V) and load-dump (40 V). Exceeding 42 V risks permanent damage per Section 5.1 of the datasheet.
Does TLV9361QDCKRQ1 support rail-to-rail input operation?
No, TLV9361QDCKRQ1 supports rail-to-rail *output* but has a limited input common-mode range of V– to (V+) – 2 V. This means the input cannot swing within 2 V of the positive rail. For true rail-to-rail input capability, consider alternatives like the OPA991QDBVRQ1 - but TLV9361QDCKRQ1's input range is sufficient for most single-supply sensor interfaces where VCM stays ≥2 V below V+.
What is the thermal shutdown threshold for TLV9361QDCKRQ1?
The TLV9361QDCKRQ1 activates thermal protection when junction temperature exceeds 170°C, forcing the output into high-impedance state to prevent damage. Recovery occurs once TJ falls below the hysteresis threshold. This behavior is documented in Section 6.3.2 and validated across SC70-5 thermal metrics (RθJA = 202.4°C/W).
Is TLV9361QDCKRQ1 pin-compatible with other TLV936x-Q1 variants?
No - TLV9361QDCKRQ1 (SC70-5) is not pin-compatible with TLV9362-Q1 (8-pin SOIC/VSSOP/TSSOP) or TLV9364-Q1 (14-pin SOIC/TSSOP). Each variant has distinct pin counts and functions. The SC70-5 layout is unique to the single-channel TLV9361-Q1 family members, including TLV9361QDCKRQ1 and TLV9361QDBVRQ1.
What does the 'Q1' suffix signify in TLV9361QDCKRQ1?
The 'Q1' suffix indicates AEC-Q100 qualification for automotive applications. TLV9361QDCKRQ1 is certified to Grade 1 (–40°C to +125°C ambient), with HBM ±2 kV and CDM ±1.5 kV ESD ratings, and full PPAP documentation support - distinguishing it from commercial-grade TLV9361 variants that lack automotive qualification testing and traceability.
