Product details
Overview
TLV9004QPWRQ1 from Texas Instruments is a quad-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, ADAS sensor interfaces, and infotainment system analog stages.
For engineers reviewing the TLV9004QPWRQ1 datasheet, TLV9004QPWRQ1 pinout, TLV9004QPWRQ1 application, or TLV9004QPWRQ1 equivalent, this page delivers verified electrical specs, automotive-grade thermal and ESD ratings, quad-channel pin mapping for TSSOP-14, functional safety capability documentation, and validated alternatives for space-constrained automotive PCBs.
Technical Context
The TLV9004QPWRQ1 uses a complementary CMOS input stage enabling true rail-to-rail input (extending 100mV beyond rails) and a class-AB output stage delivering 20mV rail-to-rail swing into 10kΩ. Its resistive open-loop output impedance (1.2kΩ at 1MHz) simplifies stability with capacitive loads up to 500pF.
It integrates RFI/EMI filtering, supports single-supply operation down to 1.8V, and features no phase reversal during overdrive-critical for automotive sensor signal integrity. Functional safety capability is documented per ISO 26262 requirements for ASIL-B systems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad-channel automotive op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV334QDRQ1 | Higher 160µA/ch quiescent current; 1.2MHz GBW; no integrated EMI filter | Less suitable for always-on, low-power modules; requires external RFI suppression | Choose when higher bandwidth is needed and board space permits external filtering |
| TSV914IQDT | Lower 50µA/ch IQ; 8MHz GBW; non-AEC-Q100; 125°C max operating temp not guaranteed | Not qualified for automotive safety-critical use; limited thermal validation | Acceptable only for non-safety infotainment peripherals with relaxed qualification requirements |
Compared with LMV334QDRQ1 and TSV914IQDT, TLV9004QPWRQ1 uniquely balances ultra-low IQ (60µA), AEC-Q100 Grade 1 assurance, integrated EMI rejection, and rail-to-rail performance - making it optimal for thermally constrained, safety-compliant automotive signal chains where power and noise immunity are co-critical.

FAQ
What is the maximum capacitive load the TLV9004QPWRQ1 can drive stably?
The TLV9004QPWRQ1 is characterized to drive up to 500pF capacitive load stably in unity-gain configuration. Its resistive open-loop output impedance (1.2kΩ at 1MHz) enables predictable phase margin behavior beyond this value-verified by Figure 6-26 showing ≥70° phase margin at 1nF load. For designs exceeding 500pF, TI recommends verifying stability with actual layout parasitics using the device's SPICE model. TLV9004QPWRQ1 maintains unity-gain stability without external compensation across its full operating range.
Does TLV9004QPWRQ1 support dual-supply operation?
Yes, TLV9004QPWRQ1 supports dual-supply operation from ±0.9V to ±2.75V (total supply 1.8V–5.5V). Pin 11 (V−) serves as the negative rail reference, and pin 4 (V+) as the positive rail. The rail-to-rail input extends 100mV beyond both rails, enabling full common-mode range utilization-for example, ±2.5V supplies allow input signals from –2.6V to +2.6V. All specifications in the datasheet-including offset voltage and noise-are validated across this dual-supply range. TLV9004QPWRQ1 performs identically in single- and dual-supply modes.
How does the TLV9004QPWRQ1 handle input overvoltage conditions?
TLV9004QPWRQ1 features diode-clamped inputs rated for continuous common-mode voltage from (V−) − 0.5V to (V+) + 0.5V and differential voltage up to (V+) − (V−) + 0.2V. Input current must be limited to ≤10mA if signals exceed these ranges. Critically, the device exhibits no phase reversal when overdriven-a key differentiator confirmed in Figure 6-27. This prevents catastrophic control loop errors in sensor interfaces where transient overvoltage is common. TLV9004QPWRQ1 maintains functional integrity under such stress, unlike many general-purpose op amps.
Is TLV9004QPWRQ1 pin-compatible with other quad op amps in TSSOP-14?
No, TLV9004QPWRQ1 has a unique pinout optimized for automotive layout: V+ is on pin 4, V− on pin 11, and outputs occupy pins 1, 7, 8, and 14-differing from industry-standard arrangements like LM324 or MCP6004. Substituting without PCB revision risks misconnection and damage. Always verify pin mapping against Table 5-3 in the SBOS980G datasheet. TLV9004QPWRQ1's pin assignment prioritizes supply decoupling proximity and channel separation, not legacy compatibility.
What functional safety documentation is available for TLV9004QPWRQ1?
Texas Instruments provides a dedicated Functional Safety Manual (SPRM613) for TLV9004QPWRQ1, including FIT rate (116.5 failures per billion hours), failure mode distribution, safety mechanisms (e.g., ESD structure robustness, no-phase-reversal design), and diagnostic coverage analysis for ASIL-B systems. The manual supports ISO 26262 hardware development workflows and is accessible via TI's product folder. TLV9004QPWRQ1 itself contains no configurable safety features-it relies on intrinsic robustness, which is fully documented. No additional safety firmware or external monitors are required for basic ASIL-B compliance.
