Product details
Overview
TLV9004QDRQ1 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 signal conditioning in low-side current sensing, ADAS sensor interfaces, and infotainment power monitoring.
For engineers reviewing the TLV9004QDRQ1 datasheet, TLV9004QDRQ1 pinout, TLV9004QDRQ1 application, or TLV9004QDRQ1 equivalent, this page delivers verified electrical specs, SOIC-14 package details, automotive-grade thermal performance (RθJA = 115.1°C/W), functional safety capability, and real-world design context for precision analog front-ends in harsh environments.
Technical Context
The TLV9004QDRQ1 uses a complementary input stage (N- and P-channel pairs) enabling true rail-to-rail input operation down to –0.1V below V– and up to +0.1V above V+, with a defined transition region where PSRR and CMRR degrade. Its class-AB output stage achieves 20mV rail-to-rail swing into 10kΩ at 5.5V.
It features resistive open-loop output impedance (1200Ω at 1MHz), enabling stable operation with ≥500pF capacitive loads without external compensation-critical for driving ADC inputs or long PCB traces in automotive body control modules.

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV324QDRQ1 | Lower bandwidth (1MHz same), higher IQ (130µA/ch), no integrated RFI filter, wider offset (±3mV) | Less suitable for low-noise, EMI-heavy ADAS or current-sense apps requiring <1mV offset | Choose for cost-sensitive, non-safety-critical body electronics where EMI immunity is secondary |
| TSV914IQDT | Higher bandwidth (8MHz), higher IQ (88µA/ch), rail-to-rail I/O, but not AEC-Q100 qualified | Not approved for automotive production; limited to prototyping or non-safety systems | Use only in pre-production evaluation or industrial applications lacking automotive qualification requirements |
Compared with LMV324QDRQ1 and TSV914IQDT, TLV9004QDRQ1 uniquely combines AEC-Q100 Grade 1 qualification, 60µA ultra-low IQ, integrated RFI filtering, and ±0.4mV precision in a quad SOIC package-making it the only option qualified for production ADAS and power-train current sensing where functional safety and EMI robustness are mandatory.

The TLV900x-Q1 product line was designed specifically for AEC-Q100-compliant, low-voltage (1.8V–5.5V), rail-to-rail input/output operational amplifier applications in space-constrained automotive subsystems requiring low power, high capacitive-load drive, and EMI resilience.
FAQ
What is the maximum capacitive load the TLV9004QDRQ1 can drive while remaining stable?
The TLV9004QDRQ1 is characterized for stable operation with up to 500pF capacitive load without external compensation, thanks to its resistive open-loop output impedance. This is confirmed in the datasheet's Figure 6-24 and 6-25, which show overshoot remains below 5% at 500pF for both G=1 and G=–1 configurations. For loads exceeding 500pF, a small series resistor (e.g., 10Ω–50Ω) at the output is recommended to maintain phase margin above 45°.
Does TLV9004QDRQ1 support single-supply operation?
Yes, TLV9004QDRQ1 fully supports single-supply operation from 1.8V to 5.5V. Its rail-to-rail input extends 0.1V beyond both supply rails (V– – 0.1V to V+ + 0.1V), and rail-to-rail output swings to within 20mV of either rail into 10kΩ. This enables direct interfacing with 3.3V or 5V microcontrollers and ADCs without level-shifting circuitry.
What is the overload recovery time of TLV9004QDRQ1, and why does it matter in automotive applications?
The TLV9004QDRQ1 has an overload recovery time of 850ns (0.85µs), specified in Section 6.7. This fast recovery prevents signal distortion during transient overvoltage events-such as load dump or inductive kickback in motor control circuits-and ensures timely resumption of linear operation in safety-critical ADAS sensor conditioning paths.
Is TLV9004QDRQ1 pin-compatible with other quad op-amps in SOIC-14 packages?
No, TLV9004QDRQ1 is not pin-compatible with generic SOIC-14 quad op-amps like LM324 or TL074. Its pinout (e.g., V+ on pin 4, V– on pin 11, NC on pin 11) is unique to the TLV900x-Q1 family. Substitution requires PCB layout revision. Always verify pin functions using Table 5-3 in the SBOS980G datasheet before replacement.
How does the integrated RFI filter in TLV9004QDRQ1 improve system-level EMI performance?
The integrated RFI filter in TLV9004QDRQ1 provides >120dB electromagnetic interference rejection ratio (EMIRR+) at 1GHz, as shown in Figure 6-35. This suppresses conducted and radiated RF noise from cellular, Bluetooth, and keyless entry systems-preventing corruption of low-level sensor signals in infotainment and ADAS ECUs without requiring external ferrite beads or RC filters.
