Product details
Overview
TLV9002QDRQ1 from Texas Instruments is a dual-channel, AEC-Q100 Grade 1 automotive operational amplifier with rail-to-rail input/output, 1MHz unity-gain bandwidth, ±0.4mV max input offset voltage, 60µA per channel quiescent current, and operation from 1.8V to 5.5V supply. It serves as a precision signal-conditioning front-end in low-side current sensing and sensor interface circuits within infotainment, ADAS, and body electronics systems.
For engineers reviewing the TLV9002QDRQ1 datasheet, TLV9002QDRQ1 pinout, TLV9002QDRQ1 application, or TLV9002QDRQ1 equivalent, this page delivers verified electrical specs, SOIC-8 package layout, automotive-grade reliability data, functional safety capability documentation, and real-world implementation context for design-in decisions.
Technical Context
The TLV9002QDRQ1 uses a complementary CMOS input stage enabling true rail-to-rail input (extending 100mV beyond rails) and a class-AB output stage delivering rail-to-rail swing within 20mV of supplies into 10kΩ loads. Its resistive open-loop output impedance (1.2kΩ at 1MHz) simplifies stability with capacitive loads up to 500pF.
It features integrated RFI/EMI filtering, no phase reversal under overdrive, unity-gain stability, and functional safety capability support-enabling use in ASIL-B–relevant subsystems without external fault monitoring circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8V to 5.5V - supports direct connection to 3.3V or 5V automotive domains and enables single-supply operation in battery-powered modules |
| Unity-Gain Bandwidth | 1MHz - sufficient for DC–100kHz sensor signal conditioning and current-sense amplification with stable closed-loop response |
| Input Offset Voltage | ±0.4mV (max at 25°C) - enables accurate sub-100mV shunt voltage measurement in low-side current sensing |
| Quiescent Current | 60µA per channel - allows dual-amplifier operation in always-on vehicle networks with <120µA total IQ |
| Input Bias Current | ±5pA - minimizes error in high-impedance sensor interfaces (e.g., thermistors, bridge sensors) |
| Output Swing | Within 20mV of rails (RL = 10kΩ) - maximizes dynamic range when driving SAR ADCs with 0–VCC input ranges |
| EMI Rejection | Integrated RFI/EMI filter - suppresses GSM, LTE, and switching regulator noise without external ferrite beads |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel automotive op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV932QDRQ1 | Higher 170µA/ch quiescent current; 1.5MHz GBW; no integrated EMI filter | Less suitable for ultra-low-power always-on nodes; requires external RFI suppression in noisy EV powertrain zones | Select when higher bandwidth is required and EMI immunity can be added externally |

FAQ
What is the maximum capacitive load TLV9002QDRQ1 can drive while maintaining stability?
The TLV9002QDRQ1 is characterized for stable operation with up to 500pF capacitive load in unity-gain configuration. Its resistive open-loop output impedance (1.2kΩ at 1MHz) significantly improves phase margin versus conventional op-amps, allowing reliable use with long PCB traces or sensor cables without external isolation resistors. This capability is validated across –40°C to +125°C and 1.8V–5.5V supply range per TI SBOS980G datasheet Figure 6-24–6-26.
Does TLV9002QDRQ1 support true rail-to-rail output swing under all load conditions?
Yes-TLV9002QDRQ1 achieves rail-to-rail output swing within 20mV of both supply rails when driving 10kΩ loads, and within 55mV with 2kΩ loads, across its full 1.8V–5.5V supply range. This performance is enabled by its class-AB output stage with common-source transistors, as confirmed in Electrical Characteristics Table 6.7 (VO parameter) and Figure 6-12 of the official datasheet.
Is TLV9002QDRQ1 qualified for ASIL-B functional safety applications?
TLV9002QDRQ1 is Functional Safety-Capable and provides documented FIT rate, failure mode analysis, and diagnostic coverage guidance aligned with ISO 26262. While not pre-certified as an ASIL-B component, it meets the foundational hardware requirements for integration into ASIL-B systems-such as motor control feedback loops or battery monitoring-when combined with appropriate system-level diagnostics per TI's functional safety documentation (SBOS980G Section 1).
Can TLV9002QDRQ1 operate from a single 1.8V supply?
Yes-TLV9002QDRQ1 is fully specified for operation from 1.8V to 5.5V single-supply configurations. Its rail-to-rail input extends 100mV beyond both rails, and its output swings to within 35mV of each rail into 2kΩ loads at 1.8V, enabling direct interfacing with low-voltage MCUs and ADCs without level-shifting circuitry.
What is the overload recovery time of TLV9002QDRQ1, and why does it matter in automotive designs?
The overload recovery time of TLV9002QDRQ1 is 0.85µs (850ns), measured from saturated output to linear operation. This fast recovery prevents signal distortion during transient events-such as load dump or ESD-induced saturation-in critical automotive sensor interfaces and current-sense amplifiers, ensuring accurate post-event measurements without extended blanking periods.
